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 .

unreferenced date February 2011 Sodium diuranate , Na sub 2 sub U sub 2 sub O sub 7 sub 6H sub 2 sub O, is a uranium salt also known as the yellow oxide of uranium. 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.

Zippeite is a hydrous potassium uranium sulfate mineral with formula potassium K sub 4 sub uranium U oxygen O sub 2 sub sub 6 sub sulfur S O sub 4 sub sub 3 sub O hydrogen H sub 10 sub 4 water H sub 2 sub O . It forms yellow to reddish brown monoclinic prismatic crystals with perfect cleavage. The typical form is as encrustations and pulverulent earthy masses. It forms as efflorescent encrustations in underground uranium mines. It has a Mohs hardness of 2 and a specific gravity of 3.66. It is strongly fluorescent yellow in UV radiation and is a radioactive mineral. Historical usage A mineral which caught the attention of a Bohemian metallurgist, Adolf Patera in the 1850s by its striking colour. This was during the period when the fame of the Jachymov silver mines was dying out. On top of the large, forgotten pit heaps, powdery minerals began to appear, vividly coloured, originating from the decomposition of the pitchblende. These colourful layers, in which zippeite was in the majority, gave Patera the idea of utilizing the uranium minerals in the manufacture of paints. Mining began in 1859 not only for the products which resulted from uraninite s decomposition, but for uraninite itself. A variety of yellow paints were manufactured because among all the secondary minerals on the pit heap there was a prevalence of the yellow powdery coatings. Zippeite is one of the so called uranium ochres . It occurs in association with uranopilite, a monoclinic, complex water soluble alkaline with other secondary uranium minerals in the weathered veins of uranium. It was named after the Prague minerologist, F. X. M. Zippe 1791 1863 . Apart from Jachymov in Bohemia it occurs mainly near Wolsendorf in Bavaria Germany and also in Utah United States U.S. . Zippeite is no longer used for the manufacture of paints. It is used as a uranium ore, as is pitchblende. References Palache, C., H. Berman, and C.

Chemically, it is a copper uranyl phosphate and usually occurs in the form of green platy deposits. 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. As with torbernite, it is named after the Sweden Swedish chemist Tornbern Bergmann .
