Corundum-mullite brick is a type of refractory brick made from a mixture of corundum and mullite materials. Mullite is a mineral compound made from alumina and silica that has excellent thermal shock resistance and high-temperature strength. Corundum-mullite brick is known for its exceptional high-temperature resistance and thermal shock 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-mullite brick is also used in high-temperature electrical insulation and as a lining for molten metal handling equipment.
