Chrome-Alumina-Zirconia Refractories
Cr2O3-ZrO₂-Al₂O₃ brick (Chrome Zirconia Corundum Brick). By incorporating zirconium oxide into a chrome corundum matrix, this product develops a network of sealed micropores and microcracks during high-temperature service. This microstructure enhances its mechanical strength, abrasion resistance, slag erosion resistance, and thermal shock (spalling) resistance.
Application
Glass Melting Furnace; Hazardous Waste Incinerator
