Abstract

We compressed NaCl-B2 to 304 GPa and presented a pressure scale based on the Birch-Murnaghan and Vinet equations of state for this phase. The pressure difference between the two formulations of the equation of state was less than 2.0% within the pressure range of 50-364 GPa. The present data indicates that the uniaxial stress of the platinum used in the sample is 2.4 GPa and comparable with that of runs using a helium pressure medium. The compression curve of NaCl-B2 was expressed by the Birch-Murnaghan equation of state with fixed volume at ambient pressure, where V0 = 37.73(4.05) Å3, K = 47.00(46) GPa and K′ =4.10(2) based upon Matsui 's platinum scale.
