OmyaWeb Precipitated Calcium Carbonate

Precipitated calcium carbonate (PCC) is produced by precipitating a calcium salt out of a solution under defined conditions. Normally, a filtered solution of calcium hydroxide Ca(OH)2 (from burnt lime) is used as the calcium source. This must not contain any colored impurities. Calcium carbonate is precipitated by the admixture of gaseous carbon dioxide or sodium carbonate Na2CO3.

Deep in the ocean, the temperature drops and pressure increases. Calcium carbonate is unusual in that its solubility increases with decreasing temperature.

precipitation. The molar concentration of magnesium in seawater is about five times that of calcium. In marine sediments magnesium carbonate is a constituent which varies in proportion according to the organic remains producing them (Olarke and Wheeler, 1922). It is a frequent constituent of shells, but much less abundant than calcium.
