Silica brick
    Silicon brick for glass melting furnace

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.
