1. Natural Sintered Mullite Introduction
1. Mullite is also called Aluminum silicate, Sillimanite,Disthene,Cyanite,Kyanite, Safe-n-driandSilicic acid aluminum salt.
2. Mullite is a kind of premium refractory material.
3. It has the advantages of uniform expansion, extremely good thermal shock stability, high refractoriness under load , low high temperature creep, high hardness and high corrosion resistance etc.
4. It’s classified into high purity fused mullite, ordinary fused alumina, natural bauxite sintered mullite and light sintered mullite.
