Title (EN) FUSED SPINEL-ZIRCONIA GRAINS AND REFRACTORY PRODUCT OBTAINED FROM SAID GRAINS
(FR) GRAINS FONDUS DE ZIRCONE - SPINELLE ET PRODUIT REFRACTAIRE OBTENU A PARTIR DESDITS GRAINS
Abstract: front page image
(EN)The invention relates to fused grains, said grains comprising a spinel-zirconia eutectic matrix encapsulating inclusions essentially formed by a zirconia phase or a spinel phase. The overall chemical composition of the grains is as follows, expressed by weight percent in the form of oxides: more than 45.0% and less than 95.0% Zr02; more than 3.0% and less than 40.0% Al203; more than 1.0% and less than 20.0% MgO; Zr02, Al2O3 and MgO together representing at least 95.0% of the weight of the grains.
(FR)Grains fondus dans lesquels : - lesdits grains comprennent une matrice de l'eutectique zircone-spinelle enrobant des inclusions constituées essentiellement d'une phase zircone ou d'une phase spinelle, - lesdits grains présentent la composition chimique globale suivante, en pourcentages poids exprimés sous la forme d' oxydes : plus de 45,0% et moins de 95,0% de Zr02, plus de 3,0% et moins de 40,0% d'Al203, plus de 1,0% et moins de 20,0% de MgO, Zr02, AI2O3 et MgO représentent ensemble au moins 95,0% du poids desdits grains.
