Acceptor-type doping of perovskite-type La1-xSrxGa0.80-yMgyM0.20O3-δ (x = 0-0.20, y = 0.15-0.20, M = Fe, Co, Ni) leads to significant enhancement of ionic conductivity and oxygen permeability due to increasing oxygen vacancy concentration. The incre

Solid-solution formation has been found in the perovskite-type system LaGa0.85-xMg0.15(Nb0.33Mg0.66)xO3-δ (x = 0 - 0.20). Increasing dopant concentration leads to lower oxygen ionic conductivity and, at temperatures above 1000 K, higher p-type elect
