Factors Affecting Precipitation of Calcium Carbonate

precipitation increases with increasing alkalinity at a given SI and decreases with increasing pH. The change in precipitation with alkalinity and pH is due to a change in buffer intensity which varies directly with alkalinity and inversely with pH, in agreement with calcium carbonate precipitation potential (CCPP) theory (Wojtowicz 1996).

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.
