Strontium oxalate can exist either in a hydrated form (SrC 2 O 4 ·nH 2 O) or as the acidic salt of strontium oxalate (SrC 2 O 4 ·mH 2 C 2 O 4 ·nH 2 O). [2] Strontium oxalate is soluble in 20 000 parts of water; in 1 900 parts of 3.5% acetic acid, in 115 parts of the 23% acid, but less soluble in the 35% acid; readily soluble in diluted HCl ...
Ammonium fluorosilicate has three major polymorphs: α-(NH 4) 2 [SiF 6] form is cubic (space group Fm3m, No. 225) and corresponds to the mineral cryptohalite. The β form is trigonal (scalenohedral) and occurs in nature as mineral bararite. [7] A third (γ) form was discovered in 2001 and identified with the hexagonal 6mm symmetry.

Caesium peroxide or cesium peroxide is an inorganic compound of caesium and oxygen with the chemical formula Cs 2 O 2. It can be formed from caesium metal by adding a stoichiometric amount in ammonia solution, or oxidizing the solid metal directly. [1] 2 Cs + O 2 → Cs 2 O 2. It can also be formed by the thermal decomposition of caesium ...
