Calcium carbonate is a kind of avirulent, insipidity, without excitant white powder, is one of the most widely use inorganic fillers. Calcium carbonate is neutral, basically does not dissolve in water, soluble in acid. According to the different method of calcium carbonate production, the calcium carbonate can be divided into heavy calcium carbonate, light calcium carbonate, colloid calcium carbonate and calcium carbonate crystals.

Calcium carbonate is a common substances on earth, exists in aragonite and calcite, chalk, limestone, marble, travertine, etc within the rock, is also the main components of the bone or shell to the animals. Calcium carbonate is an important building material, industrial USES a wide range.

1 application in car paint

Ultrafine calcium carbonate particle size less than 80 nm, due to the good thixotropy used for automobile chassis and stone paint, and paint, the market capacity of 7 ~ 8 000 000 t/a, in the international market price for up to 1 100 ~ 1 200 $/ t.

2 application in ink

Super fine calcium carbonate used in printing ink, presents excellent dispersibility, transparency, good gloss and hiding power, as well as excellent adsorption and dry ink, it must go through activation treatment, crystal shape is spherical or cube.
