Leadsun Fused Zirconia Corundum (AZS) Brick is produced by melting high-purity alumina powder and zircon sand inside electric arc furnaces, followed by casting into molds and controlled cooling. Adopting an oxidation fusion-casting craft, our AZS brick achieves a dense, homogenous internal microstructure. It delivers outstanding glass melt corrosion resistance, superior thermal shock stability, and strong chemical erosion resistance. Widely deployed for glass melting furnaces, non-ferrous metal smelting furnaces, and high-purity steel making 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.
