ZrO₂ Reinforcement for Advanced Corrosion Resistance

Zirconia corundum brick is formulated with 32–36% ZrO₂ content, enhancing its resistance to molten glass corrosion, alkaline vapors, and aggressive fluxes. This makes each electrocast zirconium corundum brick especially suited for zones with direct glass contact.

Thermal Shock and Creep Resistance

The interlocked crystalline matrix of these refractory zirconia corundum brick options ensures reliable structural stability under rapid heating and cooling. They maintain shape and strength even during long-term operation above 1800°C.

Ultra-Low Porosity and Glass Purity

With porosity ≤1.5% and zero glass-phase inclusion, each zirconia corundum brick minimizes blistering and prevents glass contamination. This is critical for optical and borosilicate glass production.

Precision Casting for Seamless Furnace Lining

Every electrocast zirconium corundum brick is dimensionally controlled and defect-free, promoting tight joints, reduced heat loss, and uniform thermal expansion across the furnace lining.

Multiple Grades for Tailored Use

Laurel offers various refractory zirconia corundum brick grades based on ZrO₂ content (e.g., 33%, 36%), enabling use in different zones such as sidewalls, crowns, and feeder channels.
