The results on the ZrO2–FeO system studies in a neutral atmosphere are presented. The refined eutectic point has been found to correspond to a ZrO2 concentration of 10.3 ± 0.6 mol% at 1332 ± 5 °C. The ultimate solubility of iron oxide in zirconia has been determined in a broad temperature range, taking into account the ZrO2 polymorphism. A phase diagram of the pseudobinary system in question has been constructed.
