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 atoms of calcium, carbon and oxygen can organize themselves in three different ways, to form three different minerals of calcium carbonate

Buying Guide for calcium carbonate

  Buying Guide for calcium carbonate Calcium carbonate is a mineral with the formula CaCO3, which is one of the substances most used by humans. It can be produced artificially, but it is also found in eggshells and animal membranes such as snails and crabs. The pearl is also made of calcium carbonate.

Calcium carbonates, including CCP, are considered to be non-toxic. In the United States, the Food and Drug Administration has claimed that calcium carbonate is GRAS (generally recognized as safe). As long as the PCC meets certain purity requirements, it can be used as a direct food additive, a pharmaceutical product, or an indirect additive in paper products that come into contact with food. Similar acceptances and approvals exist worldwide where PCCs are widely used in these applications.

precipitated calcium carbonate manufacturers The most common arrangement for precipitated and ground calcium carbonates is the hexagonal shape known as calcite. A number of different crystal forms are possible: scalenohedral, rhombohedral and prismatic. Aragonite, which has an orthorhombic crystal structure with a discrete or grouped needle, is less common. The mineral calcium carbonate vaterite is rare and generally unstable.

PCCs have been commercially produced for a long time – since 1841. The first producer was the English company John E. Sturge Ltd., which treated the residual calcium chloride from their manufacture of potassium chlorate with soda and carbon dioxide to form what they called precipitous chalk. In 1898 a new factory was built in Birmingham using the milk of lime process, which is described in more detail below. This PCC operation is now part of the Performance Minerals group of SMI.

PCC production in the United States dates back to 1938, when the C.K. Williams Company in Adams, Massachusetts, began manufacturing PCC using limestone from their adjacent mine. This plant was acquired by Pfizer in 1962 and was part of the Performance Minerals group of SMI when our parent company, Minerals Technologies Inc., was formed in 1992.
