28/1/2019· Uranium is a chemical element with syol U and atomic nuer 92.It is a silvery-white 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 its isotopes are unstable (with half-lives of the 6 naturally known isotopes, uranium-233 to uranium-238, varying between 69 years …

Metallothermic Reduction - an overview | ScienceDirect …

Smelting to give the metals involves metallothermic reduction of fluorides or oxides, or electrochemical methods. Metal oxides are converted to fluorides by HF/Ar and purified by melting in an HF/Ar atmosphere. The fluorides are then reduced by the more electropositive calcium metal.

Uranium - wikidoc

When refined, uranium is a silvery white, weakly radioactive metal, which is slightly softer than steel, strongly electropositive and a poor electrical conductor. It is malleable, ductile, and slightly paramagnetic. Uranium metal has very high density, being approximately 70% more dense than lead, but slightly less dense than gold.

Current Issues: New Uranium Conversion/Enrichment and …

Like uranium, metallic plutonium is usually obtained by high-temperature reduction of a halide salt (plutonium tetrafluoride or plutonium trifluoride) with calcium metal. Much use is also made of the so-called direct oxidation-reduction process, whereby PuO 2 is reduced with calcium metal to plutonium metal and a calcium oxide slag:

Uranium

Uranium can be prepared by reducing uranium halides with alkali or alkaline earth metals or by reducing uranium oxides by calcium, aluminum, or carbon at high temperatures. The metal can also be produced by electrolysis of KUF 5 or UF 4 , dissolved in a molten mixture of CaCl 2 and NaCl.
