Calcium silicate

Calcium silicate is a chemical compound, composed of calcium, silicon, and oxygen. It is known for its wide range of uses in various industries, including construction, food, and pharmaceuticals.

Chemical Composition

Calcium silicate is a compound made up of two elements: calcium (Ca) and silicon (Si). The chemical formula for calcium silicate is Ca2SiO4. It is a white or off-white solid that is insoluble in water.

Production

Calcium silicate is produced industrially by heating a mixture of lime (calcium oxide) and silica (silicon dioxide) or sand in a furnace. This process is known as calcination. The resulting product is a white, crystalline powder.

Uses

Construction

In the construction industry, calcium silicate is used as a component in cement, concrete, and insulation materials. It is valued for its ability to resist high temperatures and for its excellent thermal insulation properties.

Food Industry

In the food industry, calcium silicate is used as an anti-caking agent and a food additive. It is generally recognized as safe by the Food and Drug Administration (FDA).

Pharmaceuticals

In the pharmaceutical industry, calcium silicate is used as an excipient, a substance added to drugs to improve their properties.

Health Effects

Calcium silicate is generally considered safe for human consumption. However, excessive intake can lead to gastrointestinal issues.
