Characterization of the interface between an Fe–Cr alloy and the p-type thermoelectric oxide Ca3Co4O9

•The competitive thermoelectric oxide Ca3Co4O9 and a custom Fe–Cr alloy were interfaced using spark plasma sintering.•Compared to similarly contacted Ni/Ca3Co4O9 interfaces, the high-temperature stability and electrical contact resistance were improved.•The successes and issues associated with this...
