Cobalt (II) carbonate is an inorganic compound that is also known as cobaltous carbonate. It is a reddish paramagnetic solid whose chemical or molecular formula is CoCO3. Its molecular weight is 118.941 g/mol and it has a density of 4.13 g/cm3. It is an intermediate in obtaining cobalt from their ores by hydrometallurgical purification. Spherocobaltite or sphaerocobaltite is a cobalt carbonate mineral that exists in a rose-red colour in its rare pure form, while its impure specimens exist in shades of pink to pale brown. Cobalt (II) carbonate hexahydrate on heating becomes anhydrous by 140 °C while the anhydrous cobalt (II) carbonate decomposes at 427 °C before melting into cobalt (II) oxide. It is soluble in acids and liquid ammonia, almost insoluble in alcohol, methyl acetate, water, and decomposes in hot water, and is insoluble in ethanol. It is used in the preparation of cobalt compounds, ceramics, pigments, fertilizers, and catalysts.
