Deuterium solubility and electrical resistance of palladium- rhodium alloys

摘要

The deuterium solubility and the corresponding change in electrical resistance of Pd-5.0 and -10.0 at./100 Rh alloys have been investigated at different temperatures by a gas phase method. In these studies, a decrease in low pressure deuterium solubilities and increase in plateau pressures with increasing Rh content have been observed. The decrease in lattice size with increasing Rh content seemed responsible for it. The miscibility gap decreased with increasing Rh content. Higher deuterium solubility was attained for lower Rh content alloy.
