AZS Brick is a kind of fused cast zirconia-corundum refractory brick which is short writing of abbreviation that AZS from “A” of Al2O3, “Z” of ZrO2 and “S” of SiO2. Such as No. 33 fused cast zirconia-corundum refractory brick adopts the “AZS-33#” as its abbreviation, No. 36 fused cast zirconia-corundum refractory brick adopts the “AZS-36#” as its abbreviation and No. 41 fused cast zirconia-corundum refractory brick adopts the “AZS-41#” as its abbreviation.

Composition of AZS brick

AZS Brick is a kind of white solid body that made from alumina powder and about 65% ZrO2 and 34% SiO2 with zircon sand inside, and which is poured into mould after being melted in the electric melting furnace. AZS bricks’ petrographic structure is made of eutectoid and glass phase of corundum and zirconium clinopyroxene.
