Unreferenced date December 2009 Orphan date December 2009 Uranous is the chemical term for the Redox reduced tetrapositive cation of uranium that exhibits the valence U sup 4 sup . It is one of the two common ionic states of uranium found in nature, the other being the Redox oxidised hexapositive ion called uranyl . Uranous compounds are usually unstable they revert to the oxidised form on exposure to air. Examples of these compounds include uranium tetrachloride UCl sub 4 sub and uranium tetrafluoride UF sub 4 sub , which are important in molten salt reactor applications, and uranium dioxide UO sub 2 sub , a common form of nuclear fuel . The solvated U sup 4 sup ion is normally not present in water. Most of the compounds like UCl sub 4 sub are better described with the covalent bond than an ionic bond . Minerals containing the uranous ion are more subdued in colour, typically brown or black, and occur in reducing environments. Common uranous minerals include uraninite pitchblende a crystalline variant of uraninite and coffinite Smith,Hutchinson and Blackwell, 1984 Category Cations Category Uranium Category Uranium compounds ... more details

Clarkeite is a uranium oxide mineral of composition Na,Ca,Pb sub 2 sub UO sub 2 sub sub 2 sub O,OH sub 3 sub or Na,Ca,Pb UO sub 2 sub O OH 0 1H sub 2 sub O. The color of samples varies from dark brown to reddish orange. Clarkeite forms by oxidation and replacement of uraninite late during pegmatite crystallization. Although uraninite bearing granite pegmatites are common, clarkeite is rare and occurs intimately intergrown with other uranium minerals. It is known from only two localities the Spruce Pine, North Carolina Spruce Pine pegmatite district in western North Carolina , USA , and Rajputana , in the Ajmer district, India . Clarkeite is the only known naturally occurring high temperature uranate. The general formula for ideal clarkeite is Na UO sub 2 sub O OH H sub 2 sub O sub 0 1 sub . It was named for Frank Wigglesworth Clarke 1847 1931 , American mineral chemist, and former chief chemist of the United States Geological Survey .

Along with ammonium diuranate it was a component in early yellowcake s, the ratio of the two species determined by process conditions yellowcake is now largely a mix of uranium oxide s. It is commonly referred to by the initials SDU. In the classical procedure for extracting uranium, pitchblende is broken up and mixed with sulfuric acid sulfuric and nitric acid s. The uranium dissolves to form uranyl sulfate , and sodium hydroxide is added to make the uranium precipitate as sodium diuranate. This older method of extracting uranium from its uraninite uraninite ores has been replaced in current practice by such procedures as solvent extraction , ion exchange , and Volatility chemistry volatility methods. In the past it was widely used to produce vaseline glass , the sodium salt dissolving easily into the silica matrix during the firing of the initial melt.

Thus, although uranium is not dangerously radioactive when pure, some pieces of naturally occurring Uraninite pitchblende are quite dangerous owing to their radium content. Similarly, thorium gas mantle s are very slightly radioactive when new, but become far more radioactive after only a few months of storage.

After the death of Pierre Curie in 1906, Debierne helped Marie Curie carry on and worked with her in teaching and research. In 1910, he and Marie Curie prepared radium in metallic form in visible amounts. They did not keep it metallic, however.

It can form by direct deposition from a supersaturation supersaturated solution, which produces true crystalline metatorbernite, with a dark green colour, translucent diaphaneity , and vitreous lustre. However, more commonly, it is formed by the dehydration of torbernite, which causes internal stress and breakage within the crystal structure crystal lattice , resulting in crystals composed of microscopic powder held together using Electrostatics electrostatic force, and having a lighter green colour, opaque diaphaneity, and a relatively dull lustre.
