Powders of NiO, AI203 and ZrO~ mixed in various ratios were sintered between 1200 and 1600 °C and their phase equilibria studied by X-ray diffraction and electron microscopy. Partially stabilized ZrO, (PSZ) consisting of tetragonal ZrO 2 (t-ZrO2) precipitated in the cubic ZrO 2 (c-ZrO2) matrix was n
