Abstract

The temperature dependence of the conductivity of lanthanum metaniobate was studied on samples heated in air from 100 to 1100°C. The electronic and hole conductivity components were separated by the method of a blocking electrode. The temperature dependence of the electronic conductivity of LaNb3O9 was calculated using the standard thermochemical data for Nb2O5. It is concluded that the thermodynamic approach based on the thermochemical data for oxides is applicable to calculations of the temperature dependence of conductivity in complex oxygen-containing compounds.
