Features
Ultra-high thermal resistance
Long-term operating temperature up to 1600°C, short-term resistance up to 1800°C without softening, 40% higher thermal resistance compared to traditional high-alumina bricks.
Exceptional corrosion resistance
Superior resistance to acidic/alkaline slags and glass melt, HCl resistance 3 times higher than high-alumina brick.
Durability
Service life 3 times higher (or 2 times longer) than traditional materials.
Applications
Glass Melting Furnaces
High-Abrasion Zone Applications: Coolers, Checkerwork, Crowns, Hearth Blocks, Inspection Window, Burner Blocks
