Title
(EN) CHROMIA-ALUMINA REFRACTORY
(FR) RÉFRACTAIRE OXYDE DE CHROME-ALUMINE
Abstract
(EN)
A refractory composition comprising at least 50 weight percent chromic oxide (Cr2O3), as measured by chemical analysis. The composition includes fused cbromia- containing grain, powdered chromic oxide and sintered chromia-containing grain. The fused chromia-containing grain and the sintered chromia-containing grain comprise at least 50 weight percent chromia oxide, as measured by chemical analysis.
(FR)
L'invention porte sur une composition réfractaire comprenant au moins 50 pour cent en poids d'oxyde chromique (Cr2O3), tel que mesuré par analyse chimique. La composition comprend des grains contenant de l'oxyde de chrome fondu, de l'oxyde chromique pulvérulent et des grains contenant de l'oxyde de chrome fritté. Les grains contenant de l'oxyde de chrome fondu et les grains contenant de l'oxyde de chrome fritté comprennent au moins 50 pour cent en poids d'oxyde de chrome, tel que mesuré par analyse chimique.
