Zircon Corundum Refractory Brick for Glass Furnace
The description:
zirconia-corundum refractory brick refers to refractory products with 33%~45% ZrO2 content using industrial aluminum oxide powder and selected zircon sand as raw materials. Zirconium corundum brick is mainly used in glass industry tank kiln. Zirconium corundum brick, also known as fused brick English abbreviation is AZS, is according to the three chemical components of Al2O3-Zro2-sio2 ternary phase diagram, according to the order of its content, Al2O3 takes A, ZrO2 takes Z, SiO2 takes S, the national standard uses this abbreviation, such as No. 33 fused zirconium corundum brick, abbreviated as AZS-33 #, No. 36 fused cast zirconium corundum brick, abbreviated AZS-36 #, No. 41 fused cast zirconium corundum brick, abbreviated AZS-41 #.

The feature:
Sintered zirconium corundum brick has strong resistance to glass erosion. In addition, due to the existence of partially stable quadrangular ZrO2, there is a small porosity of micro-cracks formed in the brick, and the thermal shock resistance is stronger than that of AZS fused cast brick.
