摘要：

Activity-composition relations in Al2O3-Cr2O3 solid solutions at 1500-degrees and 1600-degrees-C were determined by equilibrating members of this solid-solution series with Mo-Cr alloys of known activity-composition relations and a gas phase of known oxygen potentials. The oxide solid solution shows considerable positive deviation from ideality.
