Phase relations in the ternary system ZrO 2 –CaO–MgO were experimentally established at 1600°, 1700°, and 1750°C. The investigation was based on powder X‐ray diffractometry, scanning electron microscopy–energy dispersive spectroscopy, and electron probe microanalysis, on 24 ternary compositions. The compositions were prepared using attrition milling of respective oxides and carbonates as raw materials. The results obtained allowed construction of the corresponding isothermal sections, which verified the existence of the cubic‐ZrO 2 –CaZrO 3 phase compatibility field at the three temperatures. Finally, experimental results also were compared with the thermodynamic assessment previously reported of the system ZrO 2 –CaO–MgO.
