A uranate is a ternary oxide involving the element uranium in one of the oxidation states 4, 5 or 6. A typical chemical formula is M x U y O z , where M represents a cation. The uranium atom in uranates(VI) has two short collinear U–O bonds and either four or six more next nearest oxygen atoms. [ 1 ]
Sodium uranate may be obtained in the amorphous form by heating together urano-uranic oxide and sodium chlorate; or by heating sodium uranyl acetate or carbonate. The crystalline form is produced by adding the green oxide in small quantities to fused sodium chloride, or by dissolving the amorphous form in fused sodium chloride, and allowing ...

Uranium compounds are compounds formed by the element uranium (U). Although uranium is a radioactive actinide, its compounds are well studied due to its long half-life and its applications.
Uranyl nitrate is important for nuclear reprocessing.It is the compound of uranium that results from dissolving the decladded spent nuclear fuel rods or yellowcake in nitric acid, for further separation and preparation of uranium hexafluoride for isotope separation for preparing of enriched uranium.
Radioactive uranium compounds such as uranium oxide and sodium uranate are used to impart the colors orange-red, green, yellow and black to ceramic glaze.. Although the uranium in the glaze emits gamma rays, alpha particles, and beta particles, the gamma and alpha emissions are usually too weak to be of concern. [2]
Clarkeite is a uranium oxide mineral with the chemical formula (Na,Ca,Pb) 2 (UO 2) 2 (O,OH) 3 or (Na,Ca,Pb)(UO 2)O(OH)·0-1H 2 O.. Its color varies from dark brown to reddish orange. Clarkeite forms by oxidation and replacement of uraninite late during pegmatite crystallizat
Like all hexavalent uranium compounds, UO 3 is hazardous by inhalation, ingestion, and through skin contact. It is a poisonous, slightly radioactive substance, which may cause shortness of breath, coughing, acute arterial lesions, and changes in the chromosomes of white blood cells and gonads leading to congenital malformations if inhaled.
