Abstract

An electric field applied to the CaWO₄/V₂O₅, CaMoO₄/V₂O₅ and CaMoO₄/WO₃ systems causes grain boundary and surface transports of oxides having a low surface energy (V₂O₅ and WO₃) and their segregation on the grain surface. It was found that V₂O₅ penetrates to the inner surface of CaWO₄ much more intensively when the V₂O₅ briquette bears a negative potential: (-)V₂O₅|CaWO₄(+). The penetration of V₂O₅ and WO₃ to the inner surface of the CaMoO₄ ceramic is accompanied by a chemical interaction.
