| 发明名称 | Refractory product having high zirconia content | ||
| 摘要 | The present invention relates to a molten, fluid refractory product comprising, in weight percentages on the basis of the oxides and for a total of 100% of the oxides: ZrO2+Hf2O: remainder to 100%4.0%<SiO2<6.5%Al2O3≦0.75%0.2%<B2O3<1.5%0.3%<Ta2O5 Nb2O5+Ta2O5<1.4%Na2O+K2O<0.2%BaO<0.2%P2O5<0.15%Fe2O3+TiO2<0.55%other oxide species: <1.5% the “A/B” ratio of Al2O3/B2O3 content by weight being no higher than 1.50. The invention can be used in glass melting furnaces. | ||
