Thermal Stability of Metal Hydrides, Deuterides and Tritides

INTEREST in the stability of metal hydride materials has been stimulated by their potential use as reactor moderators and as target materials in neutron generating devices which could find widespread application in compact activation analysis equipment. Earlier work has scanned the thermal stability of most rare earth and yttrium dihydrides and dideuterides1–6, and the effects of varying the rare earth metal on the heats and entropies of …
