Fused Refractory Mullite 74-79% Al2O3 for Glass Smelting Blast Furnace - 1-8mm Section Sand Sizes
Fused Mullite is a premium refractory material manufactured through high-temperature fusion of alumina and silica at 1800-2000°C, forming durable mullite crystals with exceptional thermal and chemical stability.
- Excellent thermal stability and high mechanical strength
- Low thermal expansion coefficient: -6.0×10⁻⁶/°C
- Superior chemical resistance to corrosive environments
- High melting point: 1830°C
- Low porosity: 6% maximum
- Minimal glass phase: 5% maximum
