Bauxite fused mullite is a kind of crystalline composite refractory material formed by mixing and melting bauxite additives with appropriate proportion and crystallization through rapid cooling. The product has low porosity, low impurity content, high bending strength, high softening temperature under load, and small creep at high temperatures. It is widely used in glass kiln lining brick, mullite brick, large smelting blast furnace hot blast furnace brick, blast furnace low creep sillimanite brick, ceramic kiln tools, saggar, shed board, petrochemical industry, etc.
