The Study of the Oxygen Permeability of Ba0.5Sr0.5Co0.8Fe0.2O3-δ Membranes after Laser Ablation
The surfaces of Ba0.5Sr0.5Co0.8Fe0.2O3−δ (BSCFO) membranes were decorated by laser ablation treatment in order to increase the specific surface of these membranes. Arc shape stripes with width about 150µm and depth about 25µm were formed on the surface of these membranes. The oxygen permeation fluxes through these membranes were measured. Comparing with the membrane without laser ablation treatment, the oxygen permeation fluxes through the membranes with cross stripes pattern decorated on both sides after laser ablation treatment can increase by 34.7%.
