Isotopic exchange of deuterium with hydrogen of some hydrides
Exchange of deuterium was studied with commercial potassium and barium hydrides, hydrides of pure niobium and tantalum metals, yttrium hydride, and with hydrides of rare earths metals. Non-stoichiometric composition of the hydrides made impossible a quantitative evaluation of the exchange mechanism. In most cases the ability to exchange deuterium with hydride hydrogen was found to be connected with the thermal stability of the hydrides.
