Refractory Silica Bricks
Silica brick is a kind of acid refractory mainly made from tridymite, cristobalite and a small amount of residual quartz as well as glass phase. The raw refractory material is natural silica sand whose SiO2Â content should be more than 96%. The higher SiO2Â content in silica sand, the higher temperature silica bricks resist, its refractoriness under load is as high as 1640 ~ 1670. Glass kiln silica brick has high temperature and volume stability, no pollution to glass liquid, chemical corrosion resistance, small bulk density, and can reduce the weight of furnace body. It also has the ability of resistance to acidic and alkalic steam attack with high performance of flushing resistance. It is mainly used to build the doghouse crown, suspended wall of channel, top crown and inlet sealing, and also to be used to build the checker chamber, chute, combustion chamber, coking chamber and furnace arch in glass melting furnaces. Silica brick has good corrosion resistance to glass liquid. It is the preferred refractory for crown construction of glass melting furnaces, in terms of cost, strength and of defect potential.
