On the synthesis, characterization, fabrication of components and properties optimization of partially substituted lanthanum chromltes

Eight different batches of partially Ba substituted lanthanum chromites were synthesized by a modilied liquid route followed by calcination and subjected to systematic characterization. Thin sections of components were made from these chromites by tape casting technique. Optimization of the compositions of the several ingredients to be employed in this fabrication procedure was attempted. The densification data of these powder were also obtained. A brief discussion on the relationship between the chromite processing techniques, their physical properties and component characteristics was attempted from the point of view of their application as bipolar intercell connectors for Solid Oxide Fuel Cells (SOFC).
