Absolute Primary Pressure Scale to 120 GPa
Using Brillouin spectroscopy, a self‐consistent absolute primary pressure scale is now available for whole Earth's lower mantle pressure regime. This was achieved by the simultaneous measurement of densities and acoustic wave velocities of NaCl‐B2 phase up to ~120 GPa without any use of prior pressure standards. It represents a new benchmark for pressure determination for deep Earth´s boundary and internal layered structure at the bottom of the Earth's mantle.
