Abstract:

Hydrated alkaline-earth metal tungstates Ba4Ca2+xW2-xO12-2x with perovskite structure were studied by the thermogravimetry, H-1 NMR, IR, and Raman spectroscopy methods. Electrical conductivity and transfer numbers were measured with varying T,, and. The solid solutions are capable of reversibly intercalating water and can exhibit high-temperature proton transport. The localization of protons on oxygen results in the appearance of energetically nonequivalent OH groups; a small fraction of protons are present in the form of H2O and H3O+.
