Comparison of Room-Temperature Pressure Scales Using Simultaneous Volume Measurements with Laser Annealing Technique

Abstract

  In this article, room-temperature pressure scales of MgO, Au, Pt, NaCl(B2), and Ar are compared using reported volume-volume measurements up to 198 GPa with laser-annealing method. MgO: Speziale et al. 2001, Au: Hirose et al. 2008, Pt: Holmes et al. 1989, NaCl(B2): Sata et al. 2002 (MgO calibration, mBM3), and Ar: Jephcoat 1998 are consistent each other. Simultaneous volume measurements of Au and Pt using He medium are not consistent with the laser-annealed data.
