Product Description

Mullite is a raw material with high heat resistance. At present, there are mainly high purity fused mullite, ordinary fused mullite, finely sintered mullite with all natural bauxite and caustic-burned mullite.

Mullite of Ruishi Brand is made of high quality pure natural mullite ore, melted from 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 with Ruishi brand is the ideal material used in the industry such as metallurgy, ceramics, construction materials, chemicals, electricity and foundry. In the current, Ruishi Company can provide mullite with different grades and sizes according to the needs of the customers.
