Calcium silicate is a white, crystalline compound with the chemical formula Ca2SiO4. It is primarily known for its role as a high-temperature insulating material with exceptional thermal stability. Calcium silicate insulation is widely used in industrial applications, such as in the construction of furnaces, kilns, and pipelines, where it can withstand extreme temperatures and provide effective thermal insulation. This material is also non-combustible and moisture-resistant, making it suitable for fireproofing and corrosion prevention. Calcium silicate's versatility, durability, and ability to handle intense heat have made it a vital component in a range of industries requiring reliable insulation and thermal protection.
