Abstract
Values of partial conductions (ionic: protonic, oxygen, hole) and their activation energies in LaYO3 are determined at 700–1050°C, pO2 ranging from air to 10−15 Pa, and pH2O = 0.04–13.5 kPa for different versions of doping with calcium (when introduced into the lanthanum or yttrium sublattices, or into both sublattices simultaneously). The conductivity increases in the series La0.97Ca0.03YO3 − α < LaY0.97Ca0.03O3 − α < La0.985Y0.985Ca0.03O3 − α, which means that the stoichiometric composition with a 1 : 1 ratio between Y and La has the highest conductivity.
