Common fused mullite is a kind of crystal phase composite refractories,which is made of bauxite as the main raw material,quartz sand and other additives melted in the electric arc furnace and crystallized rapidly.The product has low carbon residue,low porosity,low impurity content,high bending strength,high refractoriness under load,high hardnessm,low high-temperature creep and good crystal development.With its excellent thermal shock resistance and wear resistance.
