Fused Cast High Zirconium Refractory Material

1. Product Name：Fused Cast High Zirconium Series2. Item Code：A14013. Product Introduction： Fused cast high zirconium series is a kind of refractory for special glass industry. It contains very high zirconium (≧ 94%) and lower glass phase (≦ 6%).  Due to a quite low content of Na2O, the series owns such low glass phase and strong erosion resistance. Moreover, its production is extremely difficult, especially for special shaped blocks.  With the growth of technology in recent years, many of domestic enterprises already have abilities to mass produce for commercial field of glass industry.  4. Application High Zirconium Series was firstly applied in CRT industry as early as the 1990s, and achieved remarkable outcomes. In recent years, it has been widely used in fields of oxygen-fuel furnace, electronic glass ceramics, and high alumina glass.  5. Characteristics  High zirconium series has stable physical and chemical properties and good high-temperature corrosion resistance. It has been widely used in feeder, electrode void blocks, bubble block and special glass.  ? Improving erosion resistance of below glass:Alkali-free glassGlass ceramicsBorosilicate glassOpal fluoride glassHigh alumina glassOther special glasses ? Improving quality of below glass: Alkali-free glassCRT glassLead glassBorosilicate glassOpal fluoride glassHigh alumina glassPlasma display panel glass 6. Physical and Chemical Indicators ItemsIndexRemarkAl2O3≧%1.2ZrO2≧94.2Na2O≦0.3SiO2≦4.0Fe2O3 +TiO2≦0.3Physical IndicatorsItemsUnitIndexRemarkTrue DensityKg/m35420C.C.Spa≧3.5X108(3500kg/cm2)R.U.L (0.2MPa)℃≧1750At 850-1200℃，the volume increased after 25 thermal cycles≦0.3%  We will provide the most suitable refractory product and quotation based on different customer demands.
