Mullite ceramics, being changed tradition ceramics' production formula, uses the natural rich aluminum nature raw material and the superfine high-activity raw material, reduces the mullite formation reaction potential barrier and the synthesis temperature, causes it to fire in the process to have massive acicular and the columnar mullite crystalling phase, improved the traditional ceramics' microscopic structure, thus achieved strengthened, the plasticizing goal to the ceramics. The product’s heat shock stability is extremely good, the thermal stability is fine, the high temperature slow change value is small, the inflation is even, degree of hardness is big, the anti-acid and alkali corrodes, the anti-chemistry corrosiveness is good. Mainly used in profession remote infrared ray cookwares, the air drying, the contacting combustion, the petrochemical fining, the sewage treatment and so on,for metallurgy, coal, chemical industry and so on.
