Density 2.9g/mLat25°C(lit.)
Melting point1540°C[CRC10]
Water solubilityinsolubleH2O[HAW93]
SolubilityAlmost insoluble in water; forms gels with inorganic acids. It can absorb up to 2.5 times its weight in liquid and remain a free-flowing powder.
PH value 9.5-11.5 (5%inH2O) Properties:
1.Physical Properties:Calcium silicate is a white crystalline solid, odourless and tasteless.
2.Chemical Properties:Calcium silicate can be decomposed into oxygen and silicon dioxide at high temperature, and can also react with acid to produce the corresponding calcium salt.
Uses:
1. Mostly used in building materials: calcium silicate is commonly used in cement and concrete.
2. As a filler: it can be used as a filler in the manufacture of plastics, rubber and paper and other products.
3. In metallurgical industry: calcium silicate can be used to prepare protective slag for steel and ferroalloys.
