In this paper, the structural, elastic and thermodynamic properties of CdO under different pressure range have been reported. An extended interaction potential model (including the zero point energy effect) has been used for this study. Phase transition pressures are associated with a sudden collapse in volume. At compressed volume, the present oxide is found in cesium chloride (CsCl) phase. The calculated second order elastic constants and their various combinations have been reported in different pressure range. The calculated values have been compared with available results. Our values have been found in good agreement with existing findings.
