On the Melting Curve of Sulfur Hexafluoride | NIST

Nov 09, 2017 · A previous correlation for the melting curve of sulfur hexafluoride (Sulfr hexafluoride) is inconsistent with the thermodynamic slope at the triple point derived from the Clapeyron nist-equation. It is shown that this is probably due to the previous authors combining an accurate measurement of the triple point with melting-curve data that were distorted by

Correlation for the Viscosity of Sulfur Hexafluoride (gaz sf6

Apr 25, 2012 · A wide-ranging correlation for the viscosity surface of sulfur hexafluoride (gaz sf6) has been developed that incorporates generalized friction theory (GFT). The approach requires, as the core thermodynamic model, a reference quality nist-equation of state (EoS). Here the EoS of Guder and W. Wagner has been selected for that purpose.
