Contribution $agrave$ l'$eacute$tude de l'effect de la pression sur le couple platine/platine-rhodi$eacute$ 10%

Abstract

Measurements of the variation with pressure of the melting temperatures of gold and silver have been performed with a platinum/platinum-10% rhodium thermocouple under hydrostatic conditions. From the results, we deduce a decrease of thermocouple EMF with pressure which corresponds to 0·5±0·2 °C kbar−1 in the temperature range 960-1100 °C.

Behavior of the Elements at High Pressures

“…studies of this effect have been published. A critical review on this subject is beyond the scope of this paper, so the interested reader is referred to the papers presented at the Symposium on the Accurate Characterization of the High Pressure Environment [34,148,156,175,416] and to four papers that have appeared since the Symposium [155,243,246,367]. One of the Symposium papers [175] is a review which covers all of the important earlier works.…”
