| 摘要 |
A fused and cast refractory product containing, in weight percentages on the basis of the oxides and for a total of 100%: ZrO2: remainder up to 100% Hf2O: <5% SiO2: 2% to 10% 0.9%<Y2O3+CeO2+CaO+MgO≰4.0% B2O3:≰4.5% B2O3:≧0.09×(Y2O3+⅓(CeO2+CaO+MgO))×SiO2 Al2O3: 0.3% to 2.0% Na2O+K2O:≰0.5% P2O5: <0.05% Fe2O3 TiO2: <0.55% other species: <1.0%, as long as the Y2O3 content is no lower than 0.5% and the CeO2 +CaO+MgO content is no lower than 2%.
