Effect of Synthesis Conditions on Membrane Performance

Dionysiou et al. [97] controlled the porosity of SrCco osTbo 0503 membranes by varying the intermediate calcination temperature of the green powder and the final sintering temperature of the membrane disks. The membranes made of 

Perovskite-structured membranes, in the form of thin films supported on porous ceramic or metal substrates, have been studied extensively in the past decade. Thin films offer several advantages including reduced material cost, improved mechanical strength and possibly higher H2 flux. Chemical vapor deposition (CVD) [99], electrochemical vapor deposition (EVD) [100] and sputtering [101] represent typical methods. However, dense films have been difficult to obtain by these methods. It was found that the continuity and gas-tightness of the deposited films were very sensitive to the morphologies and pore size of substrates.
