Properties of Light Calcium Carbonate PCC Industrial Grade:
White powder or colorless crystals. Odorless. Tasteless. There are two crystals, one is the orthorhombic crystals of aragonite, another is the hexagonal rhombohedral crystal calcite. At approximately 825 ° C is decomposed into calcium oxide and carbon dioxide. Soluble in dilute acid, almost insoluble in water. The aragonite: relative density is 2.83, melting point 825 ° C (decomp.). Calcite: Relative density (d25.2) 2.711, melting point 1339 ° C (10.39MPa). Irritant, can be devided into synthetic and natural calcium carbonate.
Appliation of Light Calcium Carbonate PCC Industrial Grade:
