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, being the liner of
furnace and thermal insulating layer. It is a economical and long
life ideal products.
