Anwendungen & Verwendung
Beschreibung
The anhydrous Co3(PO4)2 is obtained when cobalt(II) salts are heated with phosphoric acid. The octahydrate Co3(PO4)2.8H2O is precipitated when aqueous solutions of cobalt(II) chloride and potassium hydrogen phosphate are mixed. As it is a brilliant lavender colour it is used in artists' paints and as a pigment in ceramics. The pyrophosphate Co2P2O7.8H2O is similarly precipitated using sodium pyrophosphate and a cobalt(II) solution.
