| Abstract: | The defect model and the relationship between conductivity and oxygen pressure at high temperature of MgO-CoO-NiO materials were investigated in this paper. The energy gap and the thermodynamic parameters of defects were estimated also. The experimental results are in good accordance with the theoretical values. |
