Mullite is a raw material with high heat resistance. It is made of high quality pure natural mullite ore, melted in the advanced industrial furnace with high temperature. It is featured by uniform expansion, excellent thermal shock resistance, high softening point with load, low elevated temperature creep value, high hardness, good resistance to chemical corrosion etc. Mullite is the ideal material used in the industry such as metallurgy, ceramics, construction materials, chemicals, electricity and foundry.
