Detailed Product Description

Fireproof Refractory Insulating Fire Brick , Fused Silica Bricks High Compressive Strength

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.
