Silicon brick for glass melting furnace Manufacturer & silicon brick Supplier from China

1. Silicon brick is the main refractory bricks used in glass melting furnace ; its main crystal phase is Tridymite .
2. Main characters:
（1）High refractoriness under load.
（2）High heat conductivity.
（3）Good thermal shock resistance.
（4）Solidity stable of capacity in high temperature.
3. Applications: Due to the low creep features, the silicon bricks for glass melting furnace are mainly used to build the main arch of the glass melting furnace.
