Product Description

Product Description

Silica refractory bricks are high-silica content refractory materials specially designed for high-temperature industrial furnaces. With SiO2 content typically above 93%, these bricks provide excellent refractoriness under load, strong structural stability at high temperatures, and superior resistance to thermal creep.

Features

1. High Refractoriness Under Load
Silica bricks maintain structural integrity even under sustained high temperatures and mechanical load, making them suitable for crown and superstructure areas.

2. Excellent Thermal Stability at High Temperature
Unlike many refractory materials, silica bricks exhibit minimal deformation at high working temperatures.

3. Strong Resistance to Acid Slag
High SiO2 content provides good resistance to acidic environments commonly found in coke ovens and glass furnaces.

4. Stable Volume After First Firing
After initial expansion during first heating, silica bricks remain dimensionally stable.

5. Dense and Hard Structure
Dense microstructure improves durability and long service life.

Applications

Coke oven chambers
Glass melting furnaces
Hot blast stoves
Regenerator checker walls
Furnace crowns and superstructures
