High zirconia fused cast blocks

Description

    HZFC*5 high zirconia fused cast blocks be made by high purity ZrO2/zirconia, the ZrO2 content more than *3.5%, the apparent porosity less than 1%, it have the characteresistics of high mechanical strength and strong erosion-resistant. 
    When it be used in the glass furnace, it can improve the quality of glass metal, and almost no pollution to glass.
    When it be used in the glass fiber kiln, it can increase the glass fiber's output, reduce the broken rate of glass fiber.
