Cubic ZrO 2 is stabilized at room temperature by the addition of AIN. The percentage of c‐ZrO 2 in the mixture of c‐ZrO 2 and m‐ZrO 2 increases linearly with the addition of up to 20 mol% AIN and decreases thereafter. Stabilization becomes complete at 50 mol% AIN. The lattice spacing of the cubic phase gradually expands up to 20 mol% AIN. A displacement reaction ZrO 2 + AIN → ZrN+Al 2 O 3 occurs above 20 mol% AIN and is completed at 50 mol% AIN.
