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 .

Precipitated Calcium Carbonate. PCC stands for Precipitated Calcium Carbonate—also known as purified, refined or synthetic calcium carbonate. It has the same chemical formula as other types of calcium carbonate, such as limestone, marble and chalk: CaCO3. The calcium, carbon and oxygen atoms can arrange themselves in three different ways, to form three different calcium carbonate .

The research showed that the crystal shape of precipitated calcium carbonate was lamellar when the reaction temperature, the rate of carbon dioxide, and the concentration of calcium hydroxide were 20 °C, L/min, 20%, respectively, which was conducive to .
PRECIPITATED CALCIUM CARBONATE
The calcium, carbon and oxygen atoms can arrange themselves in three different ways, to form three different calcium carbonate minerals. Precipitated calcium carbonate (PCC), a manufactured form of calcium carbonate, is made by first hydrating highcalcium quicklime, and then reacting the resulting slurry or milk oflime with carbon dioxide.
