Thermal expansion, molar volume and specific heat of diamond from 0 to 3000 K

Thermal expansion is of both practical and theoretical importance and it together with specific heat is essential for predicting a thermodynamic equation of state. We utilize a semi-empirical quasi-harmonic model to evaluate available data for diamond. The model allows us to predict the thermal prop...

Description
Summary:Thermal expansion is of both practical and theoretical importance and it together with specific heat is essential for predicting a thermodynamic equation of state. We utilize a semi-empirical quasi-harmonic model to evaluate available data for diamond. The model allows us to predict the thermal properties of the metastable diamond polymorph to 3000 K. The approach consisting of a simplified frequency spectrum with several. Einstein terms provides a convenient mathematical method where a minimum of empirical parameteres represent the thermal property.
