Thermal pressure and thermal expansivity of solids at high temperatures

Thermal pressure and thermal expansivity for sodium chloride and potassium chloride solids has been calculated at high temperatures using various Equation of State. The results from these calculations have been compared with the experimental data and the results are found to present close agreement with the experimental data. A close agreement between present study and the experiment data reveals the validity of the present work. The values of thermal pressure and thermal expansivity at high temperatures are useful to understand the thermo-elastic behavior of solids.
