Automated Apparatus for Sieverts' Studies of Metal Hydrides

摘要

An automated system, controlled by a small desktop computer, that carries out Sieverts' experiments on metal hydride systems is described. Data (equilibrium pressures versus temperatures at constant hydrogen-to-metal ratios) are recorded for later analysis and plotting. The computer also controls valve positions during the experiments. Results for two metal hydride systems, the uranium deuteride system in the plateau region and the La sub 5 sub 25 Ni hydride system at low concentrations, are presented as examples. Data included on the latter system have not been reported previously. The techniques used in Sieverts' experiments and the sources of errors are discussed. (ERA citation 06:007979)
