Precipitated Calcium Carbonate

Precipitated calcium carbonate are also known as light calcium carbonate. They are different from CaCO3 that are ground from limestone. Those would be known as heavy calcium carbonate.

Precipitated calcium carbonate uses are varied and in various industries. Calcium carbonate manufacturer made each grade of CaCO3 for different industrial uses.

Calcium carbonates are used in various rubber products including tires

Light CaCO3 or precipitated calcium carbonate uses include the following industries:

  • Rubber and Plastic
  • Paint and Ink
  • Paper
  • Sealant

Light precipitated calcium carbonate types. i.e. the mined limestone will go through a chemical production process called carbonation. The end result is a precipitated calcium carbonate which has a fine particle size.

Precipiated calcium carbonate CaCO3 for paper application has a particle size averaging below 2µ, for rubber, plastic, paint and ink, the recommended particles size averages below 0.5µ. In comparison with ground CaCO3, which on the average particles size is about 2-30µ.
