Abstract

An accurate pressure scale is essential for conducting high-pressure experiments. Simultaneous measurements of elasticity and density enable us to construct a primary pressure scale, which can independently determine the pressure, but this has been so far limited to low pressures and at ambient temperature due to the experimental difficulties. Recent development of Brillouin scattering and synchrotron X-ray diffraction techniques have proven to be highly suitable for exploring the sound velocities and lattice parameters under high-pressure and high temperature conditions. Here I describe the strategy, challenges and current status toward an establishment of primary pressure scale applicable to Mbar pressure using both Brillouin scattering and synchrotron X-ray diffraction techniques.
