Calcium Carbonate is a white powder, odourless, practically insoluble in water with chemical formula CaCO3.
Solvay produces Precipitated Calcium Carbonate (PCC) which is often confused with the ground calcium carbonate (GCC) and misunderstood as a commodity product and bundled in the same category of the GCC. However, every material has distinctly roles and different characteristics.
PCC is part of the FUNCTIONAL category of fillers, used to influence specific performances in specific applications whereas ground calcium carbonate (non-functional filler) is used primarily to reduce cost in many applications.
