What is Precipitated Calcium Carbonate? Precipitated Calcium Carbonate (PCC) is a synthetic, high-purity form of calcium carbonate produced by reacting quicklime with carbon dioxide. Unlike ground calcium carbonate, PCC enables precise control of crystal size and morphology, making it ideal for applications where surface area, brightness, and particle-size uniformity are critical. PCC is widely used as a filler or additive in specialty plastics, high-gloss paper coatings, paints, sealants, adhesives, and advanced engineered materials. In many of these markets, powders must meet strict micron size requirements to maintain performance, flowability, and dispersion in formulations.
