N2 - The pseudoternary system ZrO2‐Y2O3‐Cr2O3 was studied at 1600°C in air by the quenching method. Only one intermediate compound, YCrO3, was observed on the Y2O3−Cr2O3 join. ZrO2 and Y2O3 formed solid solutions with solubility limits of 47 and 38 mol%, respectively. The apex of the compatibility triangle for the cubic ZrO2, Cr2O3, and YCrO3 three‐phase region was located at =17 mol% Y2O3 (83 mol% ZrO2). Below 17 mol% Y2O3, ZrO2 solid solution coexisted with Cr2O3. Cr2O3 appears to be slightly soluble in ZrO2(ss).
