Oxygen permeability of transition metal-containing La(Sr,Pr)Ga(Mg)O<sub>3-δ</sub> ceramic membranes

Oxygen permeability of transition metal-containing La(Sr,Pr)Ga(Mg)O<sub>3-δ</sub> ceramic membranes

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 increase in strontium and magnesium content is accompani...
