The hydrogen uptake of Ba,(Ca, ,,x Nb, xz)O,\_s (BCN18) was studied in situ by thermogravimetry at different temperatures and water vapour pressures. The results can be described in terms of an ideal solution process. In contrast to earlier investigations on the Y b doped cerate system, the analysis

In order to study the local proton motion in complex perovskite-type protonic conductors anelastic and dielectric relaxation measurements have been carried out on the compound Ba (Ca Nb )O . Both techniques show spectra 3 1.18 1.82 92d depending on the proton concentration. From the dielectric measu
Ba Ca Nb O belongs to the class of complex perovskites recently introduced by Nowick et al. which are suitable 3 1.18 1.82 92d as high temperature proton conductors (HTPCs). Here, its synthesis is described using a procedure which starts with the preparation of a solution containing Ba and Ca as ac
