Products Overview
Our 33# Fused zirconium corundum products, abbreviated as AZS-33#, is a high-performance refractory product engineered for glass industry furnace lining service. 33# cast-cast zirconia corundum brick is abbreviated as AZS-33#. Zirconium corundum brick is also named AZS brick. It is based on three chemical components of the Al2O3-ZrO2-SiO2 ternary phase diagram with Al2O3 taking A, ZrO2 taking Z, and SiO2 taking S. The national standard uses this abbreviation. The 33# cast-cast zirconia corundum brick is widely used for linings of furnace in glass industries.
The 33# Fused zirconium corundum products product family is offered in one engineering-proven AZS33-Y chemistry grade. The AZS33-Y grade features Al2O3 as leavings content, ZrO2 content 32-36 percent, SiO2 content maximum 16 percent, Na2O content maximum 1.45 percent, Fe2O3+TiO2+CaO+MgO+Na2O+K2O content maximum 2.00 percent, and Fe2O3+TiO2 content maximum 0.30 percent for glass industry furnace lining service, with Bulk Density minimum 3.75 g/cm3, Apparent Porosity maximum 1.5 percent, Static Anti-corrosion Rate of Glass Liquid (normal soda-lime glass, 1500 °C × 36h) maximum 1.50 mm/24h, Exudation Temperature of Vitreous Phase minimum 1400 °C, Bubble Precipitation Rate (normal soda-lime glass, 1300 °C × 10h) maximum 2.0 percent, and Vitreous Phase Seepage Amount (1500 °C × 4h) maximum 2.0 percent. The grade has three casting types with Volume Weight minimum 3.45 g/cm3 for PT-QX casting, minimum 3.60 g/cm3 for ZWS casting, and minimum 3.70 g/cm3 for WS casting.
Sourced from our Xinmi City, Zhengzhou, Henan, China facility, each 33# Fused zirconium corundum products grade is engineered to ASTM, GB/T, and ISO refractory standards.
