Silica Brick is the main refractory bricks used in glass melting furnace;its main crystal phase is Tridymite.Silica Brick for glass melting furnace is used in building checker chamber, chute, combustion chamber,coking chamber,and furnace arch etc.
Silica brick for glass furnace have following characters:
（1）High refractoriness under load.
（2）High heat conductivity.
（3）Good thermal shock resistance.
（4）Solidity stable of capacity in high temperature.
