摘要

The limiting composition of beta-PdD obtained during electrolytic loading results from a complex competition between diffusion of D atoms through any surface barrier, diffusion within the bulk sample, and loss of deuterium gas from surface-penetrating cracks. Reductions in surface-crack concentration and surface-barriers an essential steps to achieve high compositions. The highest compositions within any sample are located within the surface region as a complex patch-work of values. The open circuit voltage (OCV), referenced to platinum, is useful in understanding changes in the surface composition and structure. Values as high as -1.35 V have been observed for highly loaded beta-PdD. Evidence for several new, possibly impurity stabilized structures is given. (C) 1998 Elsevier Science S.A. [References: 33]
