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.
