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 a water-soluble yellow uranium salt with the formula UO 2 (NO 3) 2 · n H 2 O.The hexa-, tri-, and dihydrates are known. [3] The compound is mainly of interest because it is an intermediate in the preparation of nuclear fuels.
Yellowcake. Yellowcake (also called urania) is a type of powdered uranium concentrate obtained from leach solutions, in an intermediate step in the processing of uranium ores.
The colour of uranyl compounds is due to ligand-to-metal charge transfer transitions at ca. 420 nm, on the blue edge of the visible spectrum. [4] [5] The exact location of the absorption band and NEXAFS bands depends on the nature of the equatorial ligands. [6]
Magnesium diuranate (MgU 2 O 7) is a compound of uranium. [1] It is known in the uranium refining industry as "MDU" and forms the major part of some yellowcake mixtures. . Yellowcakes are an intermediate product in the uranium refinin
