High-temperature sintered mullite produced by our company is formed by sintering high-quality raw materials in a tunnel kiln at the high temperature of more than 1,720℃ by an advanced production control process and a strict testing procedure, and has the advantages of high density and uniform expansion and outstanding features of very strong thermal shock resistance, low high-temperature creep value, high hardness (6-7), strong chemical corrosion resistance, rapid cooling and heating resistance and so on.

The high-temperature sintered mullite is one of raw materials preferred by factories for producing various amorphous refractory materials. The high-temperature sintered mullite which has peculiar high-temperature resistance, uniform expansion and low thermal conductivity and very strong thermal stability, can reach 1,500℃ after being used for a long time, has the refractoriness of 1,800℃, can directly contact flame, is firm and reliable, and avoids the slag falling phenomenon, is a preferred material in metallurgy industry, kiln industry and casting industry. With peculiar high porosity, light weight and strong permeability, it has high use value particularly in chemical industry and environmental protection industry, and has a wide market prospect.
