Mullite thermal insulation brick is a new type of refractory material, which has many excellent properties, such as high temperature resistance, high strength, low thermal conductivity and significant energy saving effect. This material can directly contact the flame, and is widely used in the lining of various industrial furnaces, such as cracking furnaces, hot blast furnaces, ceramic roller kilns, electric porcelain drawer kilns, glass crucibles and various electric furnaces.

The main components of mullite thermal insulation bricks are mullite and alumina, and their alumina content is generally between 65% and 75%. The crystal structure of this material is mainly mullite, which has good chemical stability and high temperature resistance. At high temperatures, mullite insulation bricks can maintain high room temperature compressive strength and thermal shock resistance, so they can withstand the temperature changes of rapid cooling and rapid heating.

In addition, the thermal conductivity of the mullite thermal insulation brick is small, which can effectively reduce the energy consumption of the furnace. At the same time, this material also has the characteristics of light weight and high strength, which can reduce the weight and volume of the furnace and facilitate transportation and installation.

In general, mullite thermal insulation brick is an excellent refractory material with wide application prospect and market potential. In the future, with the continuous promotion of energy conservation and environmental protection policies and the continuous innovation of industrial furnace technology, the market demand for mullite thermal insulation bricks will further increase.
