roduct description, Product introduction:

Calcite(calcium carbonate) is white powder, the main components is Cac03, mohs hardness is 3,the  density is from 2.6 g/cm3 to 2.8 g/cm3. The calcium content ofCalcite(calcium carbonate) is 54%. Calcite(calcium carbonate) is used as filler in friction material in order to improve the wear resistance of the friction material and reduce the cost. Calcite(calcium carbonate) is suitable for the disc brake pads,drum brake pads and clutch.According to the performance, the reference usage of Calcite(calcium carbonate) is generally from 2% to 8%.

The character of Calcite(calcium carbonate):

According to the performance, the reference usage of Calcite(calcium carbonate) is generally from 2% to 8%.

Calcite(calcium carbonate) is rich in the east, south, middle stratum of our city.The ore body is associated with marble and its fracture zone and it belongs to the low temperature hydrothermal type ore body. The calcite in the place YanZu is of three mineralization belt, the belt is 3000 meters long, 10m to 30m width. Calcite is colorless, milky white, some even have high transparency. Since many years, the Daye government organize to develop the calcite mining and the mining scale is very large. Now there are 40-50 calcite factories, some can manufacture modified ultrafine powder. The calcite can be divided into level 1, level 2 and level 3 according to the impurities content. Some calcite can be as ornamental stones, some with the excellent transparency and unique crystal can be optical materials for sale.
