Calcium Carbonate Filler

Precipitated calcium carbonate (PCC) can be produced by "calcining" limestone at very high temperature to drive off CO2, "slaking" the resulting lime by addition of water, and then treating the resulting "milk of lime" suspension with CO2 gas under highly controlled conditions of temperature, pH, and ionic composition. The process results in ...
