Measurements have been made of the temperature coefficient of resistivity, λ, versus hydrogen concentration, H/Pd, at very high concentrations in the Pd-H system. Unusually high hydrogen compositions were achieved using an electrochemical loading procedure which allowed stable Pd-H systems to be obtained. It is well known that increasing the H/Pd concentrations leads to three different phases (α, α + β, β), respectively, in the Pd-H system; the β phase is thought to end in an asymptotic limit. Possible evidence that a new phase (γ) exists, bordering the β phase at compositions H/Pd > 0.9 is reported and discussed. (C) 2000 Elsevier Science B.V.
