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
