Absorption of Hydrogen by Palladium Alloys

Interest in the absorption of hydrogen by palladium and its alloys continues at a high level. A symposium on this subject was held in Poland in July and is reported here, while a further meeting on the subject is planned there for next year. Papers included studies on the diffusion coefficient of hydrogen in gold-palladium alloys, the variation of electrical resistance with hydrogen content of palladium at low temperatures, and the absorption by palladium alloys of hydrogen at extremely high pressures. The symposium also dealt with hydrogen absorption by nickel alloys. Some of these papers parallel work on palladium and are also briefly reported here.
