Calcium carbonate is a common inorganic compound with the formula CaCO3, which is found in many natural substances such as limestone, marble, aragonite, chalk, and limestone. It is also an important building material and industrial raw material, which is widely used in many fields such as papermaking, metallurgy , glass making , alkali making , rubber , medicine , pigment and organic chemical industry .
The molecular weight of calcium carbonate is 100.09, the melting point is 1339 ° C, and the density is about 2.7 to 2.9 g/cm ³. It is a white solid, insoluble in water, but reacts with acids to form carbon dioxide. Calcium carbonate is also a weak electrolyte with good covering power and refractive index.
In addition, calcium carbonate is also the main component of many calcium supplements, and its calcium content is as high as 40%, with less side effects, relatively cheap price and high absorption rate. Calcium carbonate is better when taken after meals, because it can stimulate the secretion of stomach acid and help the dissociation and absorption of calcium ions.

Calcium carbonate Application:
1)Rubber:
it can reduce the amount of expensive natural rubber,increase its volume ,reduce costs, After adding calcium carbonate then can be obtain higher strength tensile ,tear strength and abrasion resistance than the pure Rubber vulcanizate
2)Chemical manufacturing materials
it is heat-proof, chemical corrosion-proof,cold-proof, anti-noise, shockproof and easy to process. Therefore it can be used to make doors, dry motar ,ceilings, wallboard,waterpipe,handrail of stairs,floor board and electric wire,etc.
3)Painting& coating:
it is as the filling and as the framework, Latex paint more than 30% amount are used in thick paint ,26%-60% amount are used in water-based pain
4)Plastic:
it can increase the volume of plastics, reduce the costs, improve the size, stability, hardness and tenacity of plastic products.
5)Paperpulp material:
it can fully make use of its high whiteness, affinity to water and shock intensity, low cost widely using .
6) Coal-fired power and planted sulfurization
7)Feed,pharmaceutical industry
making calcium additives, replace the original shell powder to reduce costs.
