Uranium - Wikipedia
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table.A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons.Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years.
18/08/ · The Uranium Block is an unsplicable solid foreground block. Placing a Water Bucket on a Uranium Block and using a Nuclear Detonator on it can let players fish exclusive radioactive items from it. The game does not count the Uranium Block as an actual radioactive item, and thus, it won't remove.
A uranium atom has 92 protons and 92 electrons , of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between , years and 4.
Uranium has the highest atomic weight of the primordially occurring elements. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium The half-life of uranium is about 4. Many contemporary uses of uranium exploit its unique nuclear properties. Uranium is the only naturally occurring fissile isotope , which makes it widely used in nuclear power plants and nuclear weapons.
However, because of the tiny amounts found in nature, uranium needs to undergo enrichment so that enough uranium is present. Uranium is fissionable by fast neutrons, and is fertile , meaning it can be transmuted to fissile plutonium in a nuclear reactor.
Another fissile isotope, uranium , can be produced from natural thorium and is studied for future industrial use in nuclear technology. Uranium has a small probability for spontaneous fission or even induced fission with fast neutrons; uranium and to a lesser degree uranium have a much higher fission cross-section for slow neutrons. In sufficient concentration, these isotopes maintain a sustained nuclear chain reaction.
This generates the heat in nuclear power reactors, and produces the fissile material for nuclear weapons. Depleted uranium U is used in kinetic energy penetrators and armor plating.
Uranium glass fluoresces green in ultraviolet light. It was also used for tinting and shading in early photography. The discovery of uranium in the mineral pitchblende is credited to Martin Heinrich Klaproth , who named the new element after the recently discovered planet Uranus.
Robert Oppenheimer starting in led to its use as a fuel in the nuclear power industry and in Little Boy , the first nuclear weapon used in war. An ensuing arms race during the Cold War between the United States and the Soviet Union produced tens of thousands of nuclear weapons that used uranium metal and uranium-derived plutonium The security of those weapons is closely monitored.
Since around , plutonium obtained by dismantling cold war era bombs is used as fuel for nuclear reactors. The development and deployment of these nuclear reactors continue on a global base. There is increasing interest in these power plants as they are powerful sources of CO 2 -free energy. When refined , uranium is a silvery white, weakly radioactive metal. It has a Mohs hardness of 6, sufficient to scratch glass and approximately equal to that of titanium , rhodium , manganese and niobium.
It is malleable , ductile , slightly paramagnetic , strongly electropositive and a poor electrical conductor. Uranium was the first isotope that was found to be fissile.
Other naturally occurring isotopes are fissionable, but not fissile. In a nuclear reactor, such a chain reaction is slowed and controlled by a neutron poison , absorbing some of the free neutrons. Such neutron absorbent materials are often part of reactor control rods see nuclear reactor physics for a description of this process of reactor control.
As little as 15 lb 7 kg of uranium can be used to make an atomic bomb. However, the first nuclear bomb the Gadget used at Trinity and the bomb that was detonated over Nagasaki Fat Man were both plutonium bombs. Uranium metal has three allotropic forms: . The major application of uranium in the military sector is in high-density penetrators. Tank armor and other removable vehicle armor can also be hardened with depleted uranium plates.
The use of depleted uranium became politically and environmentally contentious after the use of such munitions by the US, UK and other countries during wars in the Persian Gulf and the Balkans raised questions concerning uranium compounds left in the soil see Gulf War syndrome.
Depleted uranium is also used as a shielding material in some containers used to store and transport radioactive materials. The main use of uranium in the civilian sector is to fuel nuclear power plants. Fuel used for United States Navy reactors is typically highly enriched in uranium the exact values are classified.
In a breeder reactor , uranium can also be converted into plutonium through the following reaction: . Before and, occasionally, after the discovery of radioactivity, uranium was primarily used in small amounts for yellow glass and pottery glazes, such as uranium glass and in Fiestaware. The discovery and isolation of radium in uranium ore pitchblende by Marie Curie sparked the development of uranium mining to extract the radium, which was used to make glow-in-the-dark paints for clock and aircraft dials.
This waste product was diverted to the glazing industry, making uranium glazes very inexpensive and abundant. Besides the pottery glazes, uranium tile glazes accounted for the bulk of the use, including common bathroom and kitchen tiles which can be produced in green, yellow, mauve , black, blue, red and other colors.
Uranium salts are mordants of silk or wool. Uranyl acetate and uranyl formate are used as electron-dense "stains" in transmission electron microscopy , to increase the contrast of biological specimens in ultrathin sections and in negative staining of viruses , isolated cell organelles and macromolecules.
The discovery of the radioactivity of uranium ushered in additional scientific and practical uses of the element. The long half-life of the isotope uranium 4. Uranium metal is used for X-ray targets in the making of high-energy X-rays. The use of uranium in its natural oxide form dates back to at least the year 79 CE , when it was used in the Roman Empire to add a yellow color to ceramic glazes. Gunther of the University of Oxford in The discovery of the element is credited to the German chemist Martin Heinrich Klaproth.
While he was working in his experimental laboratory in Berlin in , Klaproth was able to precipitate a yellow compound likely sodium diuranate by dissolving pitchblende in nitric acid and neutralizing the solution with sodium hydroxide. Henri Becquerel discovered radioactivity by using uranium in A team led by Enrico Fermi in observed that bombarding uranium with neutrons produces the emission of beta rays electrons or positrons from the elements produced; see beta particle. Lise Meitner and her nephew, the physicist Otto Robert Frisch , published the physical explanation in February and named the process " nuclear fission ".
Confirmation of this hypothesis came in , and later work found that on average about 2. Nier to separate uranium isotopes for determination of the fissile component, and on 29 February , Nier used an instrument he built at the University of Minnesota to separate the world's first uranium sample in the Tate Laboratory.
After mailed to Columbia University 's cyclotron , John Dunning confirmed the sample to be the isolated fissile material on 1 March. These discoveries led numerous countries to begin working on the development of nuclear weapons and nuclear power. On 2 December , as part of the Manhattan Project , another team led by Enrico Fermi was able to initiate the first artificial self-sustained nuclear chain reaction , Chicago Pile An initial plan using enriched uranium was abandoned as it was as yet unavailable in sufficient quantities.
Two major types of atomic bombs were developed by the United States during World War II : a uranium-based device codenamed " Little Boy " whose fissile material was highly enriched uranium , and a plutonium-based device see Trinity test and " Fat Man " whose plutonium was derived from uranium The uranium-based Little Boy device became the first nuclear weapon used in war when it was detonated over the Japanese city of Hiroshima on 6 August Exploding with a yield equivalent to 12, tonnes of TNT , the blast and thermal wave of the bomb destroyed nearly 50, buildings and killed approximately 75, people see Atomic bombings of Hiroshima and Nagasaki.
The X Graphite Reactor at Oak Ridge National Laboratory ORNL in Oak Ridge, Tennessee, formerly known as the Clinton Pile and X Pile, was the world's second artificial nuclear reactor after Enrico Fermi's Chicago Pile and was the first reactor designed and built for continuous operation.
Argonne National Laboratory 's Experimental Breeder Reactor I , located at the Atomic Energy Commission's National Reactor Testing Station near Arco, Idaho , became the first nuclear reactor to create electricity on 20 December Other early nuclear power plants were Calder Hall in England , which began generation on 17 October ,  and the Shippingport Atomic Power Station in Pennsylvania , which began on 26 May Nuclear power was used for the first time for propulsion by a submarine , the USS Nautilus , in In , the French physicist Francis Perrin discovered fifteen ancient and no longer active natural nuclear fission reactors in three separate ore deposits at the Oklo mine in Gabon , West Africa , collectively known as the Oklo Fossil Reactors.
The ore deposit is 1. The capacity of the surrounding sediment to contain the nuclear waste products has been cited by the U. Above-ground nuclear tests by the Soviet Union and the United States in the s and early s and by France into the s and s  spread a significant amount of fallout from uranium daughter isotopes around the world.
Uranium miners have a higher incidence of cancer. An excess risk of lung cancer among Navajo uranium miners, for example, has been documented and linked to their occupation. During the Cold War between the Soviet Union and the United States, huge stockpiles of uranium were amassed and tens of thousands of nuclear weapons were created using enriched uranium and plutonium made from uranium.
Since the break-up of the Soviet Union in , an estimated short tons metric tons of highly enriched weapons grade uranium enough to make 40, nuclear warheads have been stored in often inadequately guarded facilities in the Russian Federation and several other former Soviet states.
Scientific American reported in February that in some of the facilities security consisted of chain link fences which were in severe states of disrepair. According to an interview from the article, one facility had been storing samples of enriched weapons grade uranium in a broom closet before the improvement project; another had been keeping track of its stock of nuclear warheads using index cards kept in a shoe box.
Along with all elements having atomic weights higher than that of iron , uranium is only naturally formed by the r-process rapid neutron capture in supernovae and neutron star mergers. Uranium is a naturally occurring element that can be found in low levels within all rock, soil, and water. Uranium is the 51st element in order of abundance in the Earth's crust. Uranium's average concentration in the Earth's crust is depending on the reference 2 to 4 parts per million,   or about 40 times as abundant as silver.
Some bacteria, such as Shewanella putrefaciens , Geobacter metallireducens and some strains of Burkholderia fungorum , use uranium for their growth and convert U VI to U IV. Other organisms, such as the lichen Trapelia involuta or microorganisms such as the bacterium Citrobacter , can absorb concentrations of uranium that are up to times the level of their environment.
After one day, one gram of bacteria can encrust themselves with nine grams of uranyl phosphate crystals; this creates the possibility that these organisms could be used in bioremediation to decontaminate uranium-polluted water.
In nature, uranium VI forms highly soluble carbonate complexes at alkaline pH. This leads to an increase in mobility and availability of uranium to groundwater and soil from nuclear wastes which leads to health hazards.
However, it is difficult to precipitate uranium as phosphate in the presence of excess carbonate at alkaline pH. A Sphingomonas sp.
The precipitation ability was enhanced by overexpressing PhoK protein in E. Plants absorb some uranium from soil. Dry weight concentrations of uranium in plants range from 5 to 60 parts per billion, and ash from burnt wood can have concentrations up to 4 parts per million. Other important uranium mining countries are Canada 9, t , Australia 6, t , Niger 4, t , Namibia 4, t and Russia 3, t.
Uranium ore is mined in several ways: by open pit , underground , in-situ leaching , and borehole mining see uranium mining. Extensive measures must be employed to extract the metal from its ore.
The leachate is subjected to one of several sequences of precipitation, solvent extraction, and ion exchange. Yellowcake is then calcined to remove impurities from the milling process before refining and conversion. Commercial-grade uranium can be produced through the reduction of uranium halides with alkali or alkaline earth metals. World uranium production mines and demand . Yellowcake is a concentrated mixture of uranium oxides that is further refined to extract pure uranium. It is estimated that 5.
The OECD Nuclear Energy Agency said exploration figures for would likely match those for Some nuclear fuel comes from nuclear weapons being dismantled,  such as from the Megatons to Megawatts Program. An additional 4. In , seventeen countries produced concentrated uranium oxides: Canada In the late s, UN geologists also discovered major uranium deposits and other rare mineral reserves in Somalia.
The ultimate available supply is believed to be sufficient for at least the next 85 years,  although some studies indicate underinvestment in the late twentieth century may produce supply problems in the 21st century. There is a fold increase in the amount of uranium recoverable for each tenfold decrease in ore grade. Particles with short residence times in a calciner will generally be less oxidized than those with long retention times or particles recovered in the stack scrubber.
Uranium content is usually referenced to U 3 O 8 , which dates to the days of the Manhattan Project when U 3 O 8 was used as an analytical chemistry reporting standard. Phase relationships in the uranium-oxygen system are complex.
Because of their stability, uranium oxides are generally considered the preferred chemical form for storage or disposal. Salts of many oxidation states of uranium are water- soluble and may be studied in aqueous solutions.
Unlike the uranyl salts of uranium and polyatomic ion uranium-oxide cationic forms, the uranates , salts containing a polyatomic uranium-oxide anion, are generally not water-soluble. The interactions of carbonate anions with uranium VI cause the Pourbaix diagram to change greatly when the medium is changed from water to a carbonate containing solution.
While the vast majority of carbonates are insoluble in water students are often taught that all carbonates other than those of alkali metals are insoluble in water , uranium carbonates are often soluble in water. The uranium fraction diagrams in the presence of carbonate illustrate this further: when the pH of a uranium VI solution increases, the uranium is converted to a hydrated uranium oxide hydroxide and at high pHs it becomes an anionic hydroxide complex.
When carbonate is added, uranium is converted to a series of carbonate complexes if the pH is increased. One effect of these reactions is increased solubility of uranium in the pH range 6 to 8, a fact that has a direct bearing on the long term stability of spent uranium dioxide nuclear fuels. Even higher temperatures will reversibly remove the hydrogen. This property makes uranium hydrides convenient starting materials to create reactive uranium powder along with various uranium carbide , nitride , and halide compounds.
Uranium carbides and uranium nitrides are both relatively inert semimetallic compounds that are minimally soluble in acids , react with water, and can ignite in air to form U 3 O 8. Both UC and UC 2 are formed by adding carbon to molten uranium or by exposing the metal to carbon monoxide at high temperatures. All uranium fluorides are created using uranium tetrafluoride UF 4 ; UF 4 itself is prepared by hydrofluorination of uranium dioxide.
Under the right conditions of temperature and pressure, the reaction of solid UF 4 with gaseous uranium hexafluoride UF 6 can form the intermediate fluorides of U 2 F 9 , U 4 F 17 , and UF 5.
At room temperatures, UF 6 has a high vapor pressure , making it useful in the gaseous diffusion process to separate the rare uranium from the common uranium isotope.
This compound can be prepared from uranium dioxide and uranium hydride by the following process: . One method of preparing uranium tetrachloride UCl 4 is to directly combine chlorine with either uranium metal or uranium hydride. The reduction of UCl 4 by hydrogen produces uranium trichloride UCl 3 while the higher chlorides of uranium are prepared by reaction with additional chlorine.
Bromides and iodides of uranium are formed by direct reaction of, respectively, bromine and iodine with uranium or by adding UH 3 to those element's acids. UI 5 has never been prepared. Uranium oxyhalides are water-soluble and include UO 2 F 2 , UOCl 2 , UO 2 Cl 2 , and UO 2 Br 2. Stability of the oxyhalides decrease as the atomic weight of the component halide increases.
Natural uranium consists of three major isotopes : uranium All three are radioactive , emitting alpha particles , with the exception that all three of these isotopes have small probabilities of undergoing spontaneous fission.
