Isobaric Study of the Elastic Properties for Alkaline Earth Oxides under High Temperature

الملخص EN

A simple and straightforward theoretical model is developed to investigate the elastic properties of alkaline earth oxides under the effect of temperature as well as pressure.

The calculation is performed with the help of high pressure-high temperature equation of state based on thermodynamic analysis.

The anharmonic term arising due to thermal expansion has been taken into account in the expansion of logarithmic series of the thermodynamic data.

The results obtained for alkaline earth oxides are discussed and compared with experimental data under the combined effect of high temperature and high pressure.

The results are found to be in good agreement with available experimental results.
