Al2O3 70~99 Refractory Brick Manufacturer Prices Fused And Re-Sintered Mullite Brick For Glass Kiln
Description of Fused and re-sintered mullite bricks
Fused and re-sintered mullite bricks are a type of refractory brick known for their high-temperature stability, low thermal expansion, and excellent resistance to thermal shock. They are composed primarily of mullite crystals, which are formed through the fusion and subsequent re-sintering of raw materials.
These bricks are primarily composed of mullite, which is a crystalline material composed of alumina (Al₂O₃) and silica (SiO₂). The specific composition may vary depending on the manufacturer and the intended application.
Features of Fused and re-sintered mullite bricks:
1.High Temperature Stability
2.Low Thermal Expansion
3.Excellent Thermal Shock Resistance
4.Chemical Inertness
Applications of Fused and re-sintered mullite bricks:
Fused and re-sintered mullite bricks find applications in industries such as ceramics, glass, iron and steel, non-ferrous metals, and petrochemicals. They are used in furnaces, kilns, and other high-temperature equipment.
