Product Description of Fused High Zirconia Bricks For Glass Furnaces With High Corrosion Resistance
Fused high zirconia bricks are high zrconium relraclories cast bymelting high-purity raw materials through a special process.Theerystal structure of fused high zirconia bricks is mainly composedof baddeleyite,so it has extremely high corosion resistance. lowfoaming rate and concretion rate.and hardly pellutes themolten glass.Fused high zrconia bricks are suitable for all kinds of glassfurnaces,especially high-quality glass furnaces and special glassfurnaces,such asliguld crystal substrate glass fumaces. hlghalumina glassfurnaces,borosilicate glass furnaces, halogenlighting glass furnace,glass porcelain fumace. glass fiber furnace.etc.
