Mullite insulating brick is a top thermal insulating refractory brick mainly containing mullite made of high alumina but low iron raw material with unique production technology. It was the advantages of high compression strength, good performance in high temperature, high thermal shock resistance, low thermal conductivity, powerful anti-infiltrtion, excellent wear-resistance. The brick can be used widely in metallurgy, petroleum chemistry industry, machinery, electric power ceramic etc
