Mullite is a mineral formed by aluminosilicates at high temperatures and is formed when artificially heated. Natural mullite crystals are elongated needle-like and radiate in clusters. Mullite ore is used to produce high temperature refractories with a melting point of 1870 ° C. Mullite is a kind of high-quality refractory material, it has uniform expansion, excellent thermal shock stability, high load softening point, high temperature creep value is small, high hardness, good chemical corrosion resistance, etc. At present, there are mainly high purity electric melt mullite, ordinary electric melt mullite, all natural bauxite concentrate sintered mullite and light burnt mullite. Our company produces mullite products including RM47, RM60, RM70 three kinds of products.
