Description of Glass Furnace Silica Refractory Brick Alumina Silica Fire Brick Custom Fused Silica Bricks
Fused silica brick is a high-quality refractory material known for its excellent thermal stability, low thermal expansion, and resistance to thermal shock. It is primarily composed of pure silica (SiO₂) that has been melted and fused into a dense, high-purity structure.

Fused silica bricks are almost entirely composed of silicon dioxide (SiO₂). They are made from high-purity silica sand or quartz, which is melted and then rapidly cooled to form a solid, dense structure.

Features of Fused silica brick

High Temperature Stability: Fused silica bricks are capable of withstanding extremely high temperatures, making them suitable for use in environments where extreme heat is present.

1.Low Thermal Expansion
2.Excellent Thermal Shock Resistance
3.Chemical Inertness

Applications of Fused silica brick
Fused silica bricks find applications in industries such as glass manufacturing, ceramics, metallurgy, and high-temperature processes. They are used in the construction of glass melting furnaces, coke ovens, and other high-temperature equipment.
