Product name: Industrial uses heavy calcium carbonate market price
Heavy calcium carbonate, it is made from natural carbonate minerals such as calcite, marble and limestone. It is a common powder inorganic filler with high chemical purity, inertia, difficult chemical reaction, good thermal stability, no decomposition below 400 C, high whiteness, low oil absorption rate, low refractive index, soft, dry, no crystalline water, low hardness and low wear value, non-toxic, odorless, odorless, good dispersion and other advantages.
Main content,% ( CaCO3)
Oil absorption valueml/100g
Main application: Industrial field, like plastic
White powder. Tasteless, odorless. The specific gravity is about 2.71. Decompose at 825 to 896.6 degrees. The melting point is 1339 degrees. There are two forms of amorphous and crystalline. The crystalline form can be divided into orthorhombic and hexagonal crystals, which are columnar or rhombic. It is hard to dissolve in water and alcohol. Soluble in acid, emitting carbon dioxide at the same time, exothermic reaction. It is also soluble in ammonium chloride solution. It is stable in air and has a slight moisture absorption capacity.
