The "Jun" brand fused mullite main raw materials are industrial alumina and high-quality quartz sand, which is smelted by large high-temperature electric arc furnaces. Fused mullite is the only stable binary compound in alumina-silica dual system. lt is a high-quality refractory material. The colors are gray -white, needle shaped, cylindrical crystals, and high bending strength. lt has the
characteristics of uniform expansion, good thermal shock stability， highly refractoriness under load, small high temperature creep value , high hardness,good anti -chemical corrosion etc. With its excellent heat shock resistance and abrasion resistance, it is widely used in glass kiln body furnace lining bricks,alkaline -free glass sedimentation tank mullite bricks, large smelting blast furnace hot air furnace bricks, blast-furnace low creep sillimanite brick, ceramic kiln furniture, saggar, petrochemical and other industries are raw materials for high -end refractory materials.
