EQUATION-OF-STATE BEHAVIOR FOR DIFFERENT PHASES OF LEAD UNDER STRONG COMPRESSION

[摘要] X-ray diffraction data for lead under pressures up to 80 GPa are used together with previous data covering a wider range to determine the equations of state (EOS) for the three different phases which occur under these pressures at ambient temperature. It is shown that the first-order EOS form H11, typical for ''simple'' solids,describes perfectly all the data when only the values for V-0 and K-0 are individually adapted for each phase.
