Abstract:
Based on a previously proposed modified van der Waals model for a mixture, a widerange semi-empirical equation of state for silicon dioxide with due allowance for evaporation, dissociation, and ionization is constructed. In the low-density limit, it transforms to Saha’s equation of state for a mixture of ideal gases consisting of ions and electrons. The model and simplifying assumptions used in constructing the equation of state are described. The values of constitutive parameters are given. Results of model calculations are compared with data obtained in experiments on shock compression of solid and porous quartz samples, isentropic unloading, etc.
Keywords:
