Title (EN) REFRACTIVE MATERIAL AND MOLTEN ALUMINA GRAINS
(FR) MATERIAU REFRACTAIRE ET GRAINS FONDUS A BASE D'ALUMINE
Abstract:
(EN) The invention relates to a ceramic material containing a main phase, containing more than 90 wt% alumina in the form of corundum, and a secondary phase having the following composition, in wt% on the basis of the oxides: - 40% to 90% ZrO2; - 2% to 35% TiO2; - 2% to 20% Y2O3; - less than 5% Al2O3; and - less than 2% impurities. The alumina phase is more than 70 wt% of said material, and said main phase and secondary phase together are more than 95 wt% of said material. The invention also relates to molten grains having the same composition for producing said material.
(FR) Matériau céramique, comprenant : une phase principale comprenant plus de 90 % en poids d'Alumine sous forme corindon, une phase secondaire présentant la composition suivante, en pourcentages poids sur la base des oxydes : o de 40 à 90% de Zr02, o de 2 à 35% de Ti02, o de 2 à 20% d'Y203, o moins de 5% d'Al203, o moins de 2% d'impuretés, la phase alumine représentant plus de 70% poids dudit matériau et lesdites phases principale et secondaire représentant ensemble plus de 95% du poids dudit matériau. Grains fondus de même composition pour l'obtention dudit matériau.
