Phase relations were studied in the system ZrO 2 ‐MgO with emphasis on the range 1350° to 1600°C. A phase relation was determined from samples, using precision lattice parameters, X‐ray diffraction line intensities, and petrographic observations, and from dynamic observations of the phases present using high‐temperature X‐ray diffraction techniques. Limits were established for the solubility of MgO in tetragonal ZrO 2 and for the range of the cubic solid solution. The phase relations below 1240°C were complicated by hysteresis in the monoclinic to tetragonal inversion of ZrO 2 .
