Fused silica bricks for hot repairs in glass furnaces/coke ovens

Fused silica bricks are designed for hot repairs of coke oven and glass furnace melter crowns. it has excellent thermal stability, and very very little expansion during heating-up till working temperature. fused silica bricks could replace damaged regular silica bricks without preheating and they are not prone to cracking,spalling afterwards, which makes them ideal option for hot repair purposes.
