Refractory is a material that can resist heat, pressure, or chemical corrosion and decomposition, and maintain its strength and shape at high temperatures. The main raw materials used to produce refractories are usually oxides of silicon, aluminum, magnesium, calcium, and zirconium. There are some nonoxide refractory materials, such as carbides, nitrides, borides, silicates, and graphite.
