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.

Calcium carbonate occurs naturally as calcite, marble, chalk and decomposes if heated above 800°C and gives carbon dioxide with acids (unless the calcium salt is insoluble in water). It is an approved food additive, E170. Blackboard chalk may be calcium carbonate but is more likely to be calcium sulfate. Magnesium carbonate also occurs naturally. It decomposes more easily than calcium ...
