Popis: Ceramic Sr2Ce0.95Yb0.05О4 samples have been synthesized by the Pechini process and their electrical conductivity has been determined as a function of temperature (300–900°C), and (40–2500 Pa) using four-probe and impedance measurements. In air at high temperatures, the material is a mixed oxygen–hole conductor, with predominantly oxygen-ion conductivity. At reduced temperatures, proton conductivity prevails, with σ ~
