Equation Of State And Physical-Chemical Transformations Of C-60 Fullerite At High Pressures And Temperatures

A new semiempirical equation of state for the simple cubic phase of C-60 fullerite is proposed. A critical analysis of calculated results in comparison with available high-temperature, high-pressure experimental data is made. Physical-chemical transformations observed in recent experiments on shock compression of C60 fullerite are discussed in view of equation-of-state calculations for the simple cubic phase of C60 fullerite as well as for the graphite and diamond phases of carbon.
