High pressure melting curve of platinum up to 35 GPa

In situ characterization of the high pressure – high temperature melting curve of platinum

“…However, the paper of Patel et al . 14 does not provide enough information allowing a critical comparison with the results of Errandonea 13 to be performed.…”

“…On the other hand, it is inexplicable the difference observed with the results obtained by Patel et al . 14 . In fact, the melting diagnostic adopted in their study is the same one used by Errandonea 13 i.e.…”

“…Furthermore, providing the temperature of the solid-liquid transition in SW experiment is important to reduce the Hugoniot to room temperature. For these reasons, several experimental studies have been performed to characterize the melting T of Pt at high P 10–14 . Early Pt melting experiments 10,11 were performed below 10 GPa and are in reasonable agreement with each other.…”

“…by fitting the radiated signal from the sample surface with a Planck function using the grey-body approximation 16 . The visual observation of the sample was used to detect the melting, both by direct observation of “flickering” in the laser hot-spot 12 or, by the observation of movement on the sample surface via speckle technique 13,14 . However, with the notable exception of the study of Errandonea 13 , the melting curves obtained by these techniques 12,14 are considerably lower than the one extrapolated from Mitra et al .…”
