Abstract
We measured the unit-cell volume of thermally annealed solid Ne at 30–130 GPa, which is loaded together with MgO and Pt or Au in diamond-anvil cells. Laser annealing significantly reduced the deviatoric stress and the data scatter. We fit our data to the 3rd-order Birch–Murnaghan and Vinet equations of state (EOS) with the MgO pressure scale from [Ye Y, Prakapenka V, Meng Y, Shim SH. J Geophys Res. 2017;122:3450] (hereafter MgO-Y17 scale). In order to make consistent comparison, we converted the pressures of the reported datasets for isothermal compression on Ne, so that they are consistent with the MgO-Y17 scale. The discrepancy among different datasets reduces significantly after pressure conversion. We also identified the internally consistent EOSs of Ne, MgO, Pt, Au and NaCl-B2, together with the ruby scale. Our findings contribute to internally consistent comparison of different experimental datasets on the pressure-dependent behaviors of materials.
