This Small Business Innovation Research Phase I project will focus on the production of grain boundary doped thin film mixed ionic - electronic conductors for optimized oxygen separation membranes. Ion transport properties of mixed conducting ceramics will be studied as a function of controlled grain boundary doping. Ceramics known to perform well for O2 separation will be doped with magnesium for increased performance. Doped thin films will be prepared, tested, and compared to un-doped films and films doped in the bulk rather than the grain boundary. Cost effective grain boundary doping will be accomplished through a tape casting procedure used to produce thin films which can be laminated onto porous supports for increased strength. O2 separation will be maximized while minimizing the amount of dopant used. Test structures will be mechanically characterized for strength and durability.
