Temperature dependence of bulk modulus of minerals using equation of state

Abstract

The unified theory of isobaric equation of state (EOS) has been used to obtain the temperature dependence of <i style="">V/V</i>₀of ten minerals. The model has been found to give the results in good agreement with the experimental data. The maximum deviations have been found to be less than 1% (except Mg₂SiO₄). A more critical test is provided by computing the temperature dependence of bulk modulus by using the <i style="">V/V</i>₀data obtained in the present study. Computed values of bulk modulus present a good agreement with the experimental data. This supports the validity of the simple model for complicated minerals. It is concluded that a simple model is capable to predict the properties of minerals under high temperature conditions
