Multiphase carbon and its properties in complex mixtures

PDF Version Also Available for Download.

Description

We describe some key features of a carbon three-phase equation of state and a high-pressure high temperature mixture model in which it is used. Electronic terms in the carbon model have been investigated with INFERNO (atom in a cell model). The Lindeman criterion for melting is rederived for the anisotropic structure of the graphite lattice. The curvature of the graphite melting line is constrained by the evidence for the positive slope of the diamond melting line. The importance of carbon is apparent from various experiments on shock generated mixtures. The model allows us to estimate the energy of carbon clusters ... continued below

The curvature of the graphite melting line is constrained by the evidence for the positive slope of the diamond melting line. The importance of carbon is apparent from various experiments on shock generated mixtures. The model allows us to estimate the energy of carbon clusters produced in a detonating mixture. A cluster model with specific surface structure is used to predict this energy. 41 refs., 7 figs., 4 tabs.
