Temperature Dependence of Anderson-Gruneisen Parameter for NaCl

Abstract

Considering the thermodynamic and thermoelastic properties such as the volume thermal expansion, the thermal expansivity, the isothermal bulk modulus and the Anderson-Gruneisen parameter, we find that the already existed theories presented by other workers are imperfect for NaCl. In the present communication a new expression of temperature dependence of Anderson-Gruneisen has been constructed from room temperature to melting temperature. The results show good agreement with the experimental data.
