Leadsun AZS Brick (Fused Zirconia Corundum Brick) is manufactured by melting high-purity alumina powder and zircon sand (containing ~65% ZrO₂ and ~34% SiO₂) in an electric arc furnace, followed by casting into molds and controlled cooling. This oxidation fused-cast process results in a dense, homogeneous structure with exceptional resistance to glass corrosion, thermal shock, and chemical erosion. It is widely used in glass furnaces, non-ferrous metal smelting furnaces, and pure steel furnaces.

Most widely used in glass kilns. Suitable for walls, bottoms, superstructures, and feeding channels.
Better corrosion resistance and performance with low pollution characteristics. Used in key areas such as melting pool walls near the hot spot of glass furnaces.
Best corrosion resistance, performance, and lowest contamination of glass solution. Ideal for critical parts like pool walls, feeding mouth corners, fluid holes, kiln bars, pool bottom bubbling, and all-electric melting furnaces.
