Abstract
For the realization of a practical pressure scale based on equation of state (EOS) datafor selected calibrants, a detailed modelling of the thermal contributions is required.While ‘parametric EOS’ forms with their temperature-dependent parametersV0 (T),K0 (T), andK′0 (T)are useful for limited ranges in pressure and temperature, the separate modellingof the zero-temperature and thermal contributions is more appropriate especiallyfor wide temperature ranges under high pressures (Holzapfel W B, Hartwig M andSievers W 2001 J. Phys. Chem. Ref. Data 30). The remaining uncertainties due toexplicit anharmonic contributions beyond the implicit contributions of thequasiharmonic approximation are therefore discussed here in more detail.
