electric Conductivity of Supercritical Cesium-Cesium Hydride Mixtures at High Temperatures and Pressures

摘要

Above a critical temperature of 665 deg. C liquid cesium and nonmetallic ionic liquid cesium hydride are completely miscible. This has been demonstrated previously with high pressure phase equilibrium measurements. An equilib- rium hydrogen pressure belongs to each temperature and mixture composition and is used to prepare a desired sample composition. AN autoclave for high pressure hydrogen is described into which electric conductance cells can be placed. With the cylindrical cell A the sample resistance is measured parallel to the thin stainless steel walls.
