Corundum brick is a type of refractory brick made from high-purity corundum or alumina materials. Corundum is a crystalline form of aluminum oxide that is highly resistant to high temperatures, erosion, and corrosion. Corundum brick is known for its exceptional strength and wear resistance, making it ideal for use in harsh industrial environments such as furnaces, kilns, and reactors. It is commonly used in the steel, petrochemical, and cement industries, where it can withstand extreme temperatures and chemical exposure. Corundum brick is also used in high-temperature electrical insulation and as a lining for molten metal handling equipment.
