Calcium Carbonate

Calcium carbonate (CaCO3) is a carbonate salt that makes up about 4% of the Earth's crust, found in nature as calcite, aragonite, and vaterite minerals.

For industrial use, it is either obtained by direct grinding from mines (GCC - Ground Calcium Carbonate) or chemically precipitated for higher purity (PCC).

It is insoluble in water but dissolves in acidic environments (like carbonated water) to form calcium bicarbonate.

•Increases opacity in plastics and paints, and incredibly reduces costs by decreasing the amount of resin required (acting as a filler).

•Provides an increase in optical properties in the paper industry due to its high whiteness (brightness).

✓The main inorganic additive used to increase durability in PVC pipes, cable sheathing, and plastic profiles.

✓The most important mineral filler supporting or replacing TiO2 (Titanium Dioxide) in water-based interior/exterior paints.

✓The fundamental inorganic source for cement making (as limestone) in the construction industry.
