Abstract

Ionic conductivity was measured on lanthan gallrate based ceramics under quasi-millimetre-wave (MMW) irradiation heating and conventional heating. Conductivity enhancement was evaluated for these ceramics and compared with our previous report on stabilised zirconia and doped ceria ceramics. The ionic conduction for the various amount of magnesium substituted lanthan gallrate ceramics was enhanced under MMW irradiation heating. These results are discussed in terms of the activation energies for vacancy–ion dissociation and ion transfer.
