Abstract

It is shown that the variation of a_H(2)O in the gaseous phase has little effect on the electric-field-induced drawing-in of WO₃ into the inner surface of the CaWO₄ ceramic. This suggests that WO₃ sublimation and transfer contribute insignificantly to the phenomenon under study. The activity of oxygen gas was shown to strongly influence WO₃ spreading in an electric field: the spreading rate increased with a_O(2). The electrosurface drift mobility of WO₃ depended on a_O(2) as U_WO(3) = Ka_O(2)^1/4, similarly to the variation of the concentration of holes with a_O(2). Possible explanations have been proposed.
