Fused mullite

Fused mullite is made of high-purity quartz sand and industrial alumina, melted in super large electric arc furnace, and can be processed into particles, fine powders and micro powders with different sizes. It has white color, low carbon residue and well-developed acicular crystals. With the characteristics of low porosity, low impurity content, and good thermal shock resistance and wear resistance. It is widely used in glass kiln lining brick, alkali free glass sedimentation tank, hot blast stove brick of large smelting blast furnace, low creep sillimanite brick of blast furnace, ceramic kiln furniture, box antimony, shed plate, petrochemical industry and other industries.
