Abstract
A multicomponent solid electrolyte of composition Ce0.8(Sm0.75Sr0.2Ba0.05)0.2O2 − δ has been synthesized by three different techniques: solid-state reaction, laser evaporation, and the glycine nitrate process. Its microstructure, sintering kinetics, and electrical properties have been studied in relation to the synthesis technique. Ceramics produced using laser evaporation consisted of submicron (0.2 μm) grains and offered the highest electrical conductivity: 27 × 10−3 S/cm at 873 K.
