REFRACTORY PRODUCT HAVING HIGH ZIRCONIA CONTENT |
| 摘要 |
<p>AbstractRefractory product having high zirconia contentThe 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:Zr02 + Hf20: remainder to 100%4.0% < Si02 <6.5% Al203 5 0.75%0.2%<B203<1.5% 0.3%<Ta205Nb205+ Ta205< 1.4% Na20 + K20 < 0.2% BaO < 0.2%P205 <0.15%Fe2O3 + Ti02< 0.55%other oxide species: < 1.5%the "NB" ratio of Al203 / B203 content by weight being no higher than 1.50. The invention can be used in glass melting furnaces.</p> |
