Abstract

Language:

Yttria stabilized zirconia electrolytes were sintered with addition of iron oxide or chromium oxide. The phase composition of the composites, sintering properties and DC and AC electrical properties are evaluated and compared with available data. Results show that after sintering there is only a single-phase material found in the XRD patterns. Iron can be considered a sintering promoter while chromium decreases the apparent sintering process. The addition of either oxide decreases total electrical conductivity in comparison to pure samples. Based on impedance spectra, it can be concluded that chromium mainly influences the electrical conductivity of grain boundaries, while iron influences electrical conductivity of both grain and grain boundary, with a solubility limit at grain boundaries estimated at about 2 mol% Fe.
