1.High refractoriness under load.
2.High heat conductivity.
3.Good thermal shock resistance.
4.Solidity stable of capacity
1.Silica brick is the main refractory bricks used in glass melting
furnace;It has high refractoriness
2.Silica brick for glass melting furnace is used in building
checker chamber, chute, combustion chamber,coking 3.chamber,and
furnace arch etc.
4.Silica bricks and fireclay bricks are all acid-resistant
bricks.They can be used for glass furnace and other acid
