US20030051841A1 - Method and apparatus for production of

A method and apparatus for the production of calcium carbonate and calcium silicate in common superatmospheric reactors. Multiple reactors can be provided for switching production between reactors, and advantageously utilizing process waste heat. On site production of both PCC and Calcium Silicate Hydrates is thus achieved in a paper mill.

Calcium Carbonate (CaCO3) - Uses, Preparation, Properties

At 1200K, calcium carbonate decomposes to give carbon dioxide and calcium oxide. CaCO 3 → CaO + CO 2; On reacting with dilute acids, calcium carbonate gives carbon dioxide. CaCO 3 + 2HC l → CaCl 2 + H 2 O +CO 2; Application of Calcium Carbonate. Calcium carbonate is largely employed in the pulp and paper industry.

Precipitated Calcium Carbonate (PCC) | Minerals

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 minerals.
