Calcium Carbonate is a chemical compound with formula CaCO3. It is a common substance found in rocks as the mineral calcite. For manufacturers and traders of calcium carbonate, color is commonly used as a parameter of quality. Their clients rely on color for acceptability. Calcium Carbonate manufacturers needs to consistently ensure they are regularly producing from grinding process a high white grade color for their calcium carbonate powder as a finish product which is used by various industries like manufacturing, agriculture and medicine. Calcium Carbonate has the following applications:
CaCO3 has the following applications:
industries- an ingredient utilized as filler in paper, paint, sealants and
- Agriculture and the
food industry- animal feed and agricultural lime for soil. Many foods and

ingredient in toothpaste and soap.
- Medicine- supplement to treat calcium deficiencies and an antacid for heartburn and indigestion.
To ensure a consistent color for these calcium carbonate powders, manufacturers and traders uses a colorimeter to get the lightness value of the CaCO3 grinds. Typically, the higher the lightness (L*) value, the better.
