Measurements at high temperature of integrated intensities of Bragg peaks were used to examine the defect structure in two NiO‐CoO solid solutions. The results indicate that the concentrations of vacant cation sites at 1100° to 1500°C are 4 to 10% and the tetrahedral occupations 2 to 5%. The concentration of these defects increases with temperature and partial pressure of O 2 . The mean‐square displacements of oxygen ions and cations increase with temperature and CoO concentration.
