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. It usually forms in the +4 and +6 oxidation states , although it can also form in other oxidation states.
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. In the nuclear industry, it is commonly referred to as yellow salt.

Compounds containing the uranyl ion are usually yellow, though some compounds are red, orange or green. [citation needed] Uranyl compounds also exhibit luminescence. The first study of the green luminescence of uranium glass, by Brewster [7] in 1849, began extensive studies of the spectroscopy of the uranyl ion.
Uranyl sulfate describes a family of inorganic compounds with the formula UO 2 SO 4 (H 2 O) n. These salts consist of sulfate, the uranyl ion, and water. They are lemon-yellow solids. Uranyl sulfates are intermediates in some extraction methods used for uranium ores. [1] These compounds can also take the form of an anhydrous salt.
Uranyl carbonate refers to the inorganic compound with the formula UO 2 CO 3. Also known by its mineral name rutherfordine , this material consists of uranyl (UO 2 2+ ) and carbonate (CO 3 2- ). Like most uranyl salts, the compound is a polymeric, each uranium(VI) center being bonded to eight O atoms. [ 1 ]
This hexavalent form of uranium species is known to be the most thermodynamically stable species and it is soluble in water. Even though the uranium chemistry is well explored pentavalent uranyl chemistry is under developed due to the low stability of these compounds. There are two naturally occurring pentavalent uranium-containing minerals ...
Uranium(IV) sulfate (U(SO 4) 2) is a water-soluble salt of uranium.It is a very toxic compound.Uranium sulfate minerals commonly are widespread around uranium bearing mine sites, where they usually form during the evaporation of acid sulfate-rich mine tailings which have been leached by oxygen-bearing waters.
