What is enriched uranium?? Uranium is something refined

It's very precious to make nuclear ** things.

Uranium is refined from uranium minerals. Uranium is a very heavy metal, it has an enriched energy and is abundant in nature. Uranium is found in large quantities of rocks with a state content of two to four parts per million.

It is as common as tin, tungsten and molybdenum in the craze. Uranium is also found in seawater and can be extracted and reduced from the ocean.

Uses of uranium1. Application of energy and power: Uranium has important uses in atomic power generation and ship and aircraft power, and is an efficient and clean available energy.

2. Medical applications: the rays generated by uranium decay can be used for sterilization and disinfection, clinical diagnosis and so on in medicine, 3. Military applications: uranium is used to make atomic bombs.

Missiles, aerial bombs, submarines, torpedoes, aircraft carriers and other power sources.

Uranium is refined from uranium minerals.

Uranium is an element with atomic number 92 and its element symbol U, which is the heaviest element that can be found in nature. There are three isotopes in nature, all of which are radioactive and have a very long half-life.

Hundreds of thousands of years, 4.5 billion years).

Uranium is widely found in the earth's crust and seawater. The concentration of uranium in seawater is 3 10-7%, the abundance of the earth's crust is, but it is dispersed in the earth's crust.

Uranium minerals can be divided into two categories: primary uranium ore and secondary uranium ore according to their genesis. Except for bituminous uranium ore, primary uranium ore exists in pegmatites, and primary minerals are easily transformed into various secondary minerals through weathering and hydrothermal action. The genesis, occurrence, uranium content, associated minerals and surrounding rocks of uranium ore will affect the processing technology of uranium ore.

More than 500 species of uranium and uranium-bearing minerals have been discovered. Among them, there are only twenty or thirty common ones that have industrial practical value. The important uranium minerals listed in the table below are listed.

Uranium (yóu) is named after Uranus.

The name "Uranus". In 1789, Martin Heinrich Klaproth first discovered "uranium" from bituminous uranium, and named it Uranium after a newly discovered planet in 1781, Uranus, with the element symbol U.

However, in 1841 Eugene-Melchior Peligot proved that the substance was uranium dioxide, and subsequently uranium metal was prepared by reducing UCL4 with potassium. 1896 Becquerel.

Antoine Henri Becquerel) discovered the radioactivity of uranium. At that time, the study of uranium was purely theoretical, and uranium compounds were only used for the coloring of glass and ceramics.

Uranium can form intermetallic compounds with a variety of metals. Uranium has chemical properties.

Lively, anisotropic.

Defects such as poor structural and mechanical properties. Some properties of uranium alloys are superior to metallic uranium, which is quite important in the manufacture of nuclear fuel elements. Adding the right amount of other metals such as niobium, chromium, molybdenum or zirconium can improve the thermal conductivity of uranium.

Crystal structure and metallographic structure, heat treatment characteristics, irradiation stability and corrosion resistance, etc.

Uranium is refined from uranium ore. In addition to in-situ leaching and uranium extraction from other uranium-containing materials, uranium extraction metallurgy starts from uranium ore (raw ore or concentrate), which usually includes the main steps of uranium extraction, uranium tetrafluoride production, uranium metal production, uranium hexafluoride production, uranium isotope separation, uranium metal production containing enriched U and uranium fuel element processing.

Physical. Uranium is a radioactive metal element that can be used as a fuel for nuclear reactions. Uranium is a silvery-white metal, almost as hard as steel, with a high density (relative density approx., melting point 1135, boiling point 4134). Before the development of nuclear energy, it was used to make yellow glass.

Uranium is the element with the highest atomic number found in nature. 1841 ePerley (1811-1890) isolated metallic uranium, although it had been known in bituminous uranium mines before that.

It is also found in mica uranium, vanadium-potassium uranium, and monazite; It is mainly distributed in Canada, Australia, and South Africa. The isotope uranium can be separated from the volatile gas uranium hexafluoride (UF6) by gas diffusion technology.

Uranium is refined from uranium ore. Uranium is an atomic number.

The element of 92, whose element symbol is u, is the heaviest element that can be found in nature. Uranium in 1789 by Martin Heinrich.

Claprot discovered. Uranium compounds were used in the coloring of porcelain in the early days and as nuclear fuel after the discovery of nuclear fission.

The natural isotopic composition of uranium is:

238u: natural abundance, atomic weight.

Half-life. 235u: natural abundance, atomic weight, half-life.

234u: natural abundance, atomic weight, half-life.

Among them, 235U is the only natural fissionable nuclide, which absorbs one neutron when bombarded by thermal neutrons, and then fissions, releasing a total energy of 195MeV, and releasing 2 3 neutrons at the same time, triggering chain nuclear fission; 238U is the raw material for the production of plutonium for nuclear fuel.
