Processing and Electrical Properties of Alkaline Earth‐Doped Lanthanum Gallate
Source abstract
Abstract
Alkaline earth‐doped lanthanum gallate powders were prepared by glycine/nitrate combustion synthesis. Compacts of powders synthesized under fuel‐rich conditions were sintered to densities greater than 97% of theoretical. Appropriate doping with Sr or Ba on the A‐site of the perovskite structure, and Mg on the B‐site, resulted in oxygen ion conductivity higher than that of yttria‐stabilized zirconia (YSZ), and high ionic transference numbers. Doping with Ca and Mg resulted in lower conductivity than YSZ. Thermal expansion coefficients of the doped gallates were higher than that of YSZ.
