Abstract:

For the first time ever it is demonstrated in this work that, in spontaneous conditions and following the imposition of an electric field, mutual penetration of components of WO3 and Me-2(WO4)(3) occurs at heterophase interfaces WO3 vertical bar Me-2(WO4)(3) where Me = In, Eu, or Sc. Tungstic oxide WO3 pulled onto the inner is surface of ceramic Me-2(WO4)(3) and, in turn, components of Me-2(WO4)(3) penetrate onto the surface of grains of ceramic WO3, which is confirmed by the method of x-ray-fluorescence analysis. Data concerning the conductivity and transport numbers of Eu-2(WO4)(3) and a composite on its basis, which was manufactured as a result the electrosurface transport of WO3, are obtained for the first time ever. With allowance made for the data on the O2- character of the ionic conduction in MeWO4 and Eu-2(WO4)(3) it is concluded that the type of ionic carriers in tungstates (Men+)(2/n){[}WO4] makes no impact on the mechanism of spontaneous and field-induced processes that are developing at the (Men+)(2/n){[}WO4]vertical bar WO3 interfaces.
