Detailed Description

Silica Brick Silica Refractory Brick is a kind of quality refractory materials products with over 93% SiO2 content.fire brick and refractory brick. Silica Fire Brick has excellent features of good resistance to acid corrosion, great heat conductivity, high refractoriness under load at over 1620℃. Silica Brick is fired in high temperature with quartzite as its raw material and adding a little mineralizer. Silica Bricks’ mineral composition includes tridymite, ashlar and vitric formed in high temperature. There are 50~80% quartzose content, 10~30% cristobalite and 5~15% quartz and glass phase content in the better sintering silica brick. Fire brick and refractory brick Application of Silica Brick Silica Brick is mainly used to lay coking chamber of coke oven and partition wall of combustor, kiln crown and wall of glass furnace and calcining kiln of silicate product. Use high dense silica fire brick to lay Large-scale coke oven, which can thin the wall of coking chamber and combustor to improve the production capacity.
