Description/Abstract

One of the most common types of structure which displays Mixed Electronic Ionic Conductivity is the ABO3 perovskite. The perovskite structure defines a very large range of possible oxide compositions and thus, for screening as potential SOFC cathodes, new methods must be used to obtain a complete picture of these MIEC materials. Combinatorial methods offer a route to identify the major trends in functional properties prior to full scale experiment. The system La1 − xSrxCo1 − y − zMnyFezO3 + δ (LSCMF) has been synthesised by combinatorial methods using a robot ink-dip printer. A systematic set of experiments was performed to characterise the trends in crystal structure, and non-stoichiometry with composition. It is the first time that this LSCMF pseudo-ternary has been measured with a 10% B-site substitution of cobalt, manganese and iron
