摘要

The effects of a single additive (SnO₂, Ta₂O ₅, or WO₃) on the crystal structure, densification, and electrical conductivity of the GdSmZr₂O₇ ceramic have been examined. The GdSmZr₂O₇ ceramic with or without a single additive of 1 wt.% SnO₂, Ta₂O₅, or WO ₃ sintered at temperatures between 1773 and 1973 K exhibits a single cubic pyrochlore-type phase. The relative densities of different compositions increase with increasing sintering temperature. The total conductivity of different samples obeys the Arrhenius relation. The total conductivity of the GdSmZr₂O₇ ceramic is not improved by the addition of 1 wt.% SnO₂, Ta₂O₅, or WO₃. A single additive, SnO₂, Ta₂O₅, or WO₃, is not an effective sintering aid for the GdSmZr₂O₇ ceramic.
