Abstract:The effect of the sintering additive Al2O3 on the electrical conductivity of a polycrystalline proton electrolyte based on calcium zirconate, CaZr0.95Sc0.05O3-δ (CZS) was studied. It is shown that the introduction of the sintering additive Al2O3 makes it possible to obtain dense ceramics by the combustion method at a relatively low temperature (1470 ° С). The introduction of 0.1–0.5 wt% Al2O3 leads to an increase in the grain size of ceramics from 100 nm to 1-2 μm. Al2O3 additives up to 0.3 wt% increase the el… Show more
