Feature of silica brick :
Glass furnace refractory brick 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.
