Mullite insulation brick refers to a kind of high alumina refractory material with mullite as the main crystalline phase. Mullite brick has a high refractoriness and can reach more than 1790. It is mainly used to manufacture thermal insulation layer of high temperature stove, heater and industrial kiln. It has excellent high temperature resistance, high temperature stability and thermal conductivity at high temperatures, so it is often used in the core of high temperature furnaces, such as furnaces, nozzles, high temperature air and fuel ducts.

In practical applications, mullite insulation bricks are widely used in various high-temperature furnaces, glass manufacturing, iron and steel smelting, chemical industry and other fields. It can not only ensure the efficiency and stability of the production process, but also improve the quality and output of the product. In addition, mullite insulation bricks are also widely used in aerospace, automotive manufacturing and other fields to provide efficient insulation measures for high-temperature components.
