Title (EN) CHROMIUM OXIDE REFRACTORY OBJECT AND METHODS OF FORMING THEREOF
(FR) OBJET RÉFRACTAIRE EN OXYDE DE CHROME ET PROCÉDÉS DE FORMATION DE CE DERNIER
Abstract:
(EN) A refractory object may include a Cr2O3 content of at least about 80 wt.% of a total weight of the refractory object, an Al2O3 content of at least about 0.7 wt.% and not greater than about 10.0 wt.% of the total weight of the refractory object, a SiO2 content of at least about 0.3 wt.% and not greater than about 5.0 wt.% of the total weight of the refractory object and a TiO2 content of at least about 1.0 wt.% and not greater than about 5.6 wt.% TiO2 of the total weight of the refractory object. The refractory object may further include an MOR of at least about 37 MPa as measured at 1200 C.
(FR) La présente invention concerne un objet réfractaire pouvant comprendre une teneur en Cr2O3 d'au moins environ 80 % en poids d'un poids total de l'objet réfractaire, une teneur en Al2O3 d'au moins environ 0,7 % en poids et d'au plus environ 10,0 % en poids du poids total de l'objet réfractaire, une teneur en SiO2 d'au moins environ 0,3 % en poids et d'au plus environ 5,0 % en poids du poids total de l'objet réfractaire et une teneur en TiO2 d'au moins environ 1,0 % en poids et d'au plus environ 5,6 % en poids de TiO2 du poids total de l'objet réfractaire. L'objet réfractaire peut en outre comprendre un MOR d'au moins environ 37 MPa tel que mesuré à 1 200 °C.
