Corundum brick is a highly refractory material made from a matrix of alumina and corundum, electrolytically formed from pure anode aluminum. Corundum bricks have high hardness, wear resistance, fire resistance and metal corrosion resistance, and can withstand high temperatures up to 1900°C.
Corundum brick is a high-grade refractory material with excellent performance. Due to its high temperature stability and excellent corrosion resistance, it is widely used in various equipment and facilities in high temperature fields. Corundum bricks have corrosion resistance at high temperatures and high hardness under high pressure, and are used in buildings and industrial equipment. It can also be used to manufacture high-temperature melting furnaces, refractory kilns and other equipment, with excellent wear resistance and long service life.
In addition, corundum bricks are also widely used in chemical industry, electric power, metallurgy, aviation and other industries. In nuclear power plants, aviation industry and petrochemical fields, corundum bricks are very important high refractory materials. Corundum bricks can also be used as medium for industrial furnace chambers and ultraviolet rays. In short, corundum bricks have a very wide range of applications and play an important role in harsh environments such as high temperature, high pressure, and high corrosion.
