Calcium carbonate
White or grayish white powder, odorless and odorless, easy to absorb odor, stable in the air, almost insoluble in water and ethanol, slightly hygroscopic, soluble in enoic acid (acetic acid, dilute hydrochloric acid, dilute nitric acid) and producing CO2. It is insoluble in dilute sulfuric acid and can be divided into three types according to powder size: heavy calcium carbonate (30-50 µ m), light calcium carbonate (5 µ m), and colloidal calcium carbonate (0.03-0.05 µ m).

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
