Chamotte, also known as calcined clay or flint clay, is a refractory material derived from natural clay minerals calcined at 1300°C to 1600°C. This process transforms the structure, removing organic matter and water, resulting in a stable, inert ceramic with excellent refractoriness, mechanical strength, and thermal shock resistance. It is widely used in producing refractory bricks, castables, and ceramic products for kiln linings, furnaces, and reactors in steel, cement, and glass industries. Chamotte’s low thermal conductivity and high abrasion resistance also makes it suitable for insulation and erosion resistance applications.
