Refractory materials are a specialized type of material used in petrochemical processes and other industrial applications, where they are exposed to extreme temperatures and corrosive conditions. They are able to withstand temperatures up to 2,400 °C and are composed of non-metallic elements such as alumina, magnesia, zirconia, and silica. Refractory bricks are a type of refractory material that is formed into a brick shape for use in high-temperature applications.
