Alumina Silica Fire Brick is a kind of alumina silica refractory materials, which is with features of high refractoriness, good erosion resistant and high strength. Alumina Silica Refractory Brick includes many types of firebricks such as Silica Bricks, Fireclay Brick, High Alumina Brick and Corundum Brick. Alumina Silica Fire Brick can be widely applied for various parts of industrial furnaces such as coke ovens, hot blast stoves, glass kiln and steelmaking electric furnaces.

Alumina silica fire brick is based on AL2O3—SiO2 basic theory, including several below:
Silica brick, means refractory brick with over 93% SiO2 content, is a kind of acid refractory brick, mainly used for coke oven, glass kiln, ceramic kiln, carbon calcinations furnace, but not suitable for heating equipment with temperature fluctuation under 600 ℃. Bata Tanah Liat Api is mainly made of mullite, glass phase, cristobalite and quartz. Fireclay brick is always used in Blast Furnace, hot blast heater, heating furnace, power boiler, lime kiln, rotary kiln, ceramic kiln and calcining kiln. High alumina brick is made of corundum, mullite and glass phase, which is subjected by AL2O3/ SiO2 proportions. High alumina brick is mainly used in steel manufacture, non-ferrous metals industry and other industries. Corundum brick has over 90% AL2O3 content and with corundum as the main phase. Corundum brick can be classified into sintered corundum brick and fused cast corundum brick.
