Thermal expansivity and bulk modulus of NaCI crystal at high temperatures

摘要

Relationships based on various thermodynamic approximations are discussed and used to predict values of the volume thermal expansion coefficient and isothermal bulk modulus for NaCI crystal at high temperatures. The results obtained from different formulas are compared with each other and also with experimental data. Such a comparison affords information on the suitability and approximate validity of the various thermodynamic relationships under study.
