Fused Cast AZS Brick is a kind of fused cast zirconia-corundum refractory brick with high refractoriness and high intensity and mainly used to build glass furnace for resisting high temperature and melt glass corrosion and also can save energy. Fused Cast AZS Brick is also called zirconia-corundum refractory brick which 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.
