The mullite produced by our company uses high-quality natural bauxite as raw material. It is processed through a selection process to remove impurities and undergo multi-stage homogenization treatment to ensure the uniformity of the raw material composition. The treated raw materials are then sintered at a high temperature above 1750℃. During the sintering process, the heating rate, holding time and cooling process are accurately controlled through an advanced kiln control system to allow the mullite crystals to fully grow and develop, forming a sintered mullite product with high content, high volume density, good thermal shock stability, low high-temperature creep value and good chemical corrosion resistance. This product has stable quality and is an ideal raw material for the production of various shaped and unshaped refractory materials, advanced sanitary ware blanks, precision castings and other products.
