Introduction of refractory silica brick: 
1.This series of products have natural surface, low water absorption, high bending strength, anti-freeze-thaw, durability etc. 
2. Cultural Imitate Clay Split Brick have wonderful tone, natural transition of the changeable colors and special appearance texture makes it natural beautiful, return to the ancient, rustic, steady, what's more, you could feel the modern and cultural environment. 
3. Environment protects this series of products through very high firing makes the products no impurities, non-radioactive, it's green protect product. 
4. Beautiful and economical Imitate clay split brick has original clay split brick's effect and feature, the products through high temperature firing, so the products not fade, non-anti alkali, low water absorption, what's more, with the time development, you will feel the products beautiful view to match the whole building.

Feature of silica brick : 
1.Strong acid slag resistance, 
2.High refractoriness under load, 
3.Volume shrinkage not change when reheated. 
4.Used for glass furnace.

Physical properties and chemical composition
 

Advantage of silica brick : 

1.Good acid and erosion resistance, powerful anti high-temperature strength.

2.Soften melting temperature is 1680 °C.

3.Low thermal shock resistance.

4.Natural silica as raw material, plus regular mineralizer.

5.Ensure good bonding and structural strength of furnace.

6.Good heat resistance and long service life.

Application of silica brick :

1. Silica brick is the main refractory bricks used in glass melting furnace;its main crystal phase is Tridymite.

2. Silica brick for glass melting furnace is used in building checker chamber, chute, combustion chamber,coking chamber,and furnace arch etc.

Silica Refractory Brick

 Refractory Silica brick:Wooden pallet and then polyethylene film is placed over it, finally the package is tied up with strips
