BeschreibungCobalt(II) carbonate, CoCO3, is a reddish paramagnetic solid and an intermediate in the hydrometallurgical purification of cobalt from its ores. It is an inorganic pigment, and a precursor to catalysts. Cobalt(II) carbonate also occurs as the rare red/pink mineral spherocobaltite. It is prepared by combining cobaltous sulfate and sodium bicarbonate solutions.
VerwendenCobalt(II) carbonate is precursor to cobalt carbonyl, cobalt salts and blue pottery glazes such as delftware. It is used as an essential element in dietary supplements and also used in the manufacture of paints and pigments.
synthetischeCobalt(II) carbonate is prepared by heating cobaltous sulfate, cobaltous chloride or any Co2+ salt with sodium bicarbonate in solution: CoSO4 + NaHCO3 → CoCO3 + NaHSO4
