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.

Ammonium diuranate or (ADU) ((NH 4) 2 U 2 O 7), is one of the intermediate chemical forms of uranium produced during yellowcake production. The name "yellowcake" originally given to this bright yellow salt, now applies to mixtures of uranium oxides which are actually hardly ever yellow.
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.
The compound can be prepared by treating uranium trioxide]] with acetic acid: . UO 3 + 2 CH 3 COOH + H 2 O → UO 2 (CH 3 COO) 2 ·2H 2 O. The acetate ligands of uranyl acetate can be replaced to give a variety of uranyl complexes. [6]
