Theoretical High Pressure Study for Thermoelastic Properties of NaCl-B1

The evaluation of , Bulk modulus K, Lattice parameter a, First Grneisen parameter , Second Grneisen parameter q, and Debye temperature D for NaCl-B1 under high pressure has been achieved in this work by using two equations of state (Dodson EOS and Thomsen EOS). The results obtained by the two EOSs have been compared with each other and with other theoretical and experimental data published in literature. The results obtained by using Dodson EOS show more agreement with data given in literature than the results obtained by using Thomsen EOS.
