Sintered corundum brick means that the content of Al2O3 is more than 90%, and the main crystalline phase is α- Al2O3 refractory brick. Sintered corundum brick has high temperature resistance, high hardness, oxidation resistance, corrosion resistance and good air tightness. Therefore, it has a wide range of applications.
In the production of sintered corundum brick, mullite clinker should be added in order to improve its thermal shock stability and slag resistance
In order to reduce the firing temperature, 1-2% TiO2 promoter is often added. The product can be fired at 1550-1600 ℃. MgO can inhibit the grain growth and obtain the microcrystalline structure, which is beneficial to improve the mechanical strength of the product
