Calcium silicate (CaSiO3) is an inorganic ceramic compound commonly found in natural mineral forms and produced synthetically for industrial applications. It serves as a key constituent in refractory materials, cement chemistry, and specialty ceramics where thermal stability and chemical inertness are required. Engineers select calcium silicate for applications demanding high-temperature performance, low thermal conductivity, and resistance to chemical attack, particularly in furnace linings, insulation systems, and Portland cement formulations.
