Zircon Corundum Refractory Brick
Fused Zircon Corundum Refractory Brick Erosion Resistance ISO9001
The zircon corundum refractory brick is engineered for industrial applications requiring exceptional corrosion resistance, thermal stability, and mechanical strength. Manufactured from high-purity alumina and zirconia through advanced production technology, these zircon refractory bricks are ideal for high-temperature environments with aggressive chemical exposure.
Key FeaturesP:
Superior Corrosion Resistance: The zircon corundum refractory brick resists erosion from molten glass, metal slags, and alkali vapors.
High Mechanical Strength: Zircon refractory bricks are designed with a dense, low-porosity structure to ensure long-lasting performance.
Outstanding Thermal Shock Resistance: Maintains stability under frequent heating and cooling cycles.
Extended Service Life: The combination of zirconia and alumina enhances durability in extreme industrial operations.

Description:
Fused Casting Zirconia Corundum (AZS) products were produced by baddeleyite and corundum material,made of the zirconite (Industry zirconia ) and industry alumina as the mainly mixed raw material, melting in the electric furnace, casting, annealing, machining, then finished.
The zircon corundum refractory brick and zircon refractory bricks combine superior corrosion resistance, high strength, and long service life, making them a preferred choice for industries operating in extreme conditions.
Features:
1). Fine thermal conductivity in the normal temperature.
2).Compact structure
3).Strong resistant erosion stability to the glass liquid.
4).Not color to the glass.
Applications:
Glass industry
