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 diuranate is commonly referred to by the initials SDU. [1] Along with ammonium diuranate it was a component in early yellowcakes . [ 2 ] The ratio of the two compounds is determined by process conditions; however, yellowcake is now largely a mix of uranium oxides .

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.
[1] Phase relationships in the uranium-oxygen system are complex. The most important oxidation states of uranium are uranium(IV) and uranium(VI), and their two corresponding oxides are, respectively, uranium dioxide (UO 2) and uranium trioxide (UO 3). [2] Other uranium oxides such as uranium monoxide (UO), diuranium pentoxide (U 2 O 5), and ...
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.
What Does 'Fortnight' Mean? Fortnight is a word that comes from the Old English term "fēowertīene niht." Its definition actually has to do with a set amount of time.
Clarkeite is the only known naturally occurring high-temperature uranate. The general formula for ideal clarkeite is Na[(UO 2)O(OH)](H 2 O) 0–1. It was named for Frank Wigglesworth Clarke (1847–1931), American mineral chemist, and former chief chemist of the United States Geological Survey.
