Calcium silicate, also called Ca-Si or CaSi, is the chemical compound Ca₂SiO₄, also known as calcium orthosilicate and sometimes written as 2CaO·SiO₂. It belongs to a group of compounds obtained by reacting calcium oxide with silica in various ratios, such as 3CaO·SiO₂ (Ca₃SiO₅), 2CaO·SiO₂ (Ca₂SiO₄), 3CaO·2SiO₂ (Ca₃Si₂O₇), and CaO·SiO₂ (CaSiO₃).
Calcium silicate is a white, free-flowing powder derived from limestone and diatomaceous earth. It has low bulk density and high water absorption capacity. It is commonly used in roads, insulation, bricks, roof tiles, and table salt, and also occurs in cements, where it is known as belite (C₂S in cement chemist notation). In food preparation, calcium silicate is used as an anti-caking agent and as an antacid. It is approved by the United Nations' FAO and WHO bodies as a safe food additive in a large variety of products.
Calcium silicate insulation materials include boards, pipe sections, special shapes, and high-strength parts, which are widely used in various industrial furnaces.
