Description:

Calcium Carbonate is white, odorless powder or colorless crystals. Practically insoluble in water.
Fine calcium carbonate is a white, odorless powder or colorless crystals. Practically insoluble in water. Occurs extensive in rocks world-wide. It is a common substance found in rocks as the minerals Limestone (CAS No.1317-65-3), such as Calcite (CAS No.13397-26-7); Marble (CAS No.1317-65-3); Aragonite (CAS No.14791-73-2).etc. And it is the main component of pearls and the shells of marine organisms, snails, and eggs.etc.

Ground calcium carbonate (GCC) (CAS: 471-34-1) results directly from the mining of limestone. It is made of natural carbonate minerals such as calcite, marble, limestone and so on after mechanical grinding mill. The extraction process keeps the carbonate very close to its original state of purity and delivers a finely ground product either in dry or slurry form.

Ground calcium carbonate (GCC)

Ground calcium carbonate (GCC) is a common inorganic filler powder, has high chemical purity, the inertia big, not easy to chemical reaction, good thermal stability, does not decompose under 400 ℃, high whiteness, low oil absorption rate, low refractive index, soft, dry and without water of crystallization, low hardness abrasion value of small, non-toxic, tasteless, odourless, good dispersion, etc.

According to the need for different particle size requirements of :
Ground Calcium Carbonate (GCC) , also named as Heavy Calcium Carbonate, (China Standard: HG/T 3249-2001, Heavy Calcium Carbonate and Actived Heavy Calcium Carbonate for industrial use.)
(China Standard: HG/T 3249-2013 Heavy Calcium Carbonate for industrial use. )
