Feuerfestes Material aus beta-Aluminiumoxid |
摘要 |
<p>A novel fused beta alumina refractory material has the molar composition 11.25-15.45% Na2O, Li2O and/or K2O (the Na2O content being≥9.3%), 0-2.97% SiO2, 81.38-88.75% Al2O3 and NOTGREATER 0.2% impurities,≥98% of the crystalline phase content comprising beta alumina. Preferably, the material has the composition (by wt.) 7.25-10 (preferably 7.4-8.5)% Na2O, 0-1.85 (preferably 0.7-1.45)% SiO2, 87.95-92.75 (preferably 89.85-91.9)% Al2O3 and NOTGREATER 0.2% impurities.</p> |
