A constructive approach to formulating pressure-dependent binding energy using the equation of state
摘要
This study evaluated the compression-pressure and binding energy relationship for the Srivastava-Pandey, Usual-Tait and Murnaghan equations of state (EOS). This study calculated the pressure-dependent binding energy of NaCl, LiF, and KCl. Experimental data validate the result obtained by various equations of state. All the equations of state perform well and produce similar results at low pressure, but deviation takes place at high pressure. It is seen that the Srivastava-Pandey equation of state produces better results than other equations of state at high compression because the Srivastava-Pandey equation of state considers a higher order of compression, and it is an exponential function of compression. This supports prior findings that higher-order compression terms enhance the accuracy of equations of state, highlighting the effectiveness of the Srivastava-Pandey equation of state for precise predictions. This study finds that the equation of state can also be used as a better tool to calculate pressure-dependent binding energy.
