High Compressive Strength Fused Silica Refractory Bricks For Cement Kiln And Glass Oven Coke Oven
High Compressive Strength Fused Silica Refractory Bricks For Cement Kiln And Glass Oven Coke Oven
Silica Brick Description
High quality silica brick is made of silicon raw material, the content of SiO2 is above 95%. And the content of Al2O3 is below 1.0%.
Silica Brick Advantage:
1) Silicon oxide is above 95%.
2) Good acid erosion resistance.
3) High softening point with temperature.
4) No shrink in burn repeatedly.
5) Temperature of refractoriness under load is above 1650º C .Stable Capability, High Quality.
Application of silica brick:
They are widely used for hot blast furnace, coke oven, and glass furnace. The products can be made according to customers' requirement.
