Precipitated Calcium Carbonate(PCC)
Light calcium carbonate
Product Description
Micro-scale precipitated calcium carbonate, also known as precipitated calcium carbonate, is a micron grade precipitated calcium carbonate, is the natural limestone calcined to produce lime (the main component is calcium oxide), adding water to digest the lime to produce lime milk (the main component is calcium hydroxide), in the carbon dioxide carbonated lime milk to produce calcium carbonate precipitation, by dehydration, drying and crushing. Micro-scale precipitated calcium carbonate relative density 2.7~2.9, for white, non-toxic, odorless, non-irritating white powder.
