摘要

Platinum (Pt) has been widely studied for pressure calibration in high pressure-temperature ranges. We have for the first time performed in situ synchrotron X-ray diffraction (XRD) with laser-heated diamond anvil cells to study the P-V-T equation of state (EOS) for Pt up to 95 GPa and 3150 K. MgO was used for pressure calibration. A detailed analysis of the room-temperature compression curve was fitted with the third-order Birch-Murnaghan (BM) EOS, which yields ambient volume V-0 = 60.3 A(3), isothermal bulk modulus K-0 = 308 GPa, and its pressure derivative K-0(') = 4.1. A least-squares fit of the P-V-T data to a high-temperature (BM) EOS yielded K-0(') = 5.5 +/- 2, K-0 = 274 +/- 36 GPa, alpha K-T(V-0, T) = 0.003 +/- 0.0003 GPa K-1 and (delta K-T/delta T)(V) = 0.03 +/- 0.01 GPa K-1 with V-0 = 60.3 angstrom(3) . Within a reasonable range, it is found that the EOS of this study is consistent with the known EOS of Pt. The present technique and results cover the P-T range between the resistive heating and the shock compression experimental data in the literature.
