Introduction to Silica Brick
Silica brick is a type of refractory brick that is mainly composed of silica (SiO₂). It has excellent high - temperature resistance, with a refractoriness under load generally above 1600°C. Silica bricks are widely used in various industrial furnaces, such as glass melting furnaces, coke ovens, and steelmaking furnaces. Their high thermal conductivity and good resistance to acid slag make them suitable for applications where exposure to high temperatures and acidic environments is common. The unique crystalline structure of silica bricks provides them with dimensional stability at high temperatures, which is crucial for maintaining the integrity of industrial furnaces.
