Material which was stabilized with calcia or yttria was prepared by using a novel rapid combustion route. The oxide-ion conductivities of the stabilized samples were found to be comparable to those of commercially prepared samples. Variations in the grain boundary impedance occurred as a function of composition and temperature.
