Calcined Bauxite, derived from high-quality ore calcined at over 1600°C, transforms into a dense, durable aggregate with high aluminum oxide content. This process removes impurities and enhances properties like refractoriness, thermal stability, and mechanical strength. It is primarily used in producing refractory bricks, castables, and shapes for linings, kilns and furnaces across steel, cement, and glass industries. Its resistance to abrasion, corrosion, and thermal shock makes it essential in high-temperature and harsh conditions, establishing it as a fundamental material in the refractory sector.
