Our zirconium series products take α-Al2O3, partial stable zirconium dioxide and zirconium corundum clinker as raw materials and goes through the process of mixing, molding, drying and burning in high temperature shuttle type kiln, featuring compact structure, high volume density, large unit weight, high mechanical strength at normal and high temperature, good thermal shock stability, low repeated burning shrinkage and creep property, high chemical stability and alkali media corrosion resistance. The compact zircon brick is mainly applied as middle-level brick and skew blocks in Na-Ca glass kilns. The zirconium brick is mainly applied in large glass kiln smelting pools, kinescope kilns, regenerative chamber partial wall brick and the solution corrosion parts of kilns in chemical industry and metallurgy industry. The overall dimensions, physiochemical indexes and service life of the product have reached or exceeded the level of similar products at home and abroad
