Silica Bricks
Silica Bricks
Silica Brick is the main refractory bricks used in glass melting furnaces; 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:
High refractoriness under load
High heat conductivity
Good thermal shock resistance
Solidity stable of capacity at high temperature
