The P-V-T equation of state of Au and Pt: An alternative pressure scale in high P-T experiments
The pressure-volume-temperature equations and state (EOS) of Au and Pt have been investigated to the relative volume change of 0.5–0.6 and temperature up to 3000 K based on experimental shock Hugoniot data and a simple thermal pressure model within the Mie-Grüneisen-type analysis framework. The calc...

| Summary: | The pressure-volume-temperature equations and state (EOS) of Au and Pt have been investigated to the relative volume change of 0.5–0.6 and temperature up to 3000 K based on experimental shock Hugoniot data and a simple thermal pressure model within the Mie-Grüneisen-type analysis framework. The calculated results have excellent agreement with the available volume compression data over a wide range of pressure and temperatrure. The comparison of the calculated results with the previous theoretical investigations also has been performed. The crosscheck on independent data and the excellent agreements with experimental data confirm that the present isothermal EOS for these pressure standard materials can be used as high-pressure scales for static DAC experiments. |
