CHROMIA-ALUMINA REFRACTORY

摘要

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.
