Calcite powder is heavy calcium, which is "heavy calcium carbonate ”The main component is heavy calcium carbonate, also referred to as "heavy calcium carbonate", which is commonly used as filler , widely used in artificial floor tiles, rubber, plastics, paper making coating 、 paint , ink Cable , building supplies, food, medicine, textile, feed, toothpaste and other daily chemical industries, as fillers, can increase the volume of products and reduce production costs.
chemical property
Calcite powder is mainly composed of CaCO3, and its theoretical chemical composition is: CaO: 56.03%, CO2: 43.97%, often replaced by MgO, FeO, MnO and other similar substances. Calcite powder is generally white, milky white or colorless, with density of 2.6-2.94, hardness of 3, glass luster, decomposition temperature of 898.6 ℃, dense structure, insoluble in water, soluble in acid, less impurities, uniform particle size, good processing performance, low DOP oil absorption value, etc. At the same time, calcite powder can also be used as raw material for silicate industry.
