| Abstract: | An effort has been made for obtaining higher-order elastic constants for MgO starting from basic parameters, viz. nearest-neighbor distance and hardness parameter using Coulomb and Börn-Mayer potentials. These are calculated in a wide temperature range (100–1000 K) and compared with available theoretical and experimental results. |
