Basic introduction of ground calcium carbonate

Heavy calcium carbonate, referred to as heavy calcium, is ground from natural carbonate minerals such as calcite, marble, and limestone. It is a commonly used powdery inorganic filler, with high chemical purity, high inertness, not easy to chemical reaction, good thermal stability, no decomposition under 400 ℃, high whiteness, low oil absorption, low refractive index, soft, dry, It has the advantages of no crystal water, low hardness, low abrasion value, non-toxic, tasteless, odorless, and good dispersibility.
