LaCrO3
semiconductorLanthanum chromite (LaCrO₃) is a perovskite-structured ceramic compound that exhibits semiconductor behavior along with mixed ionic-electronic conductivity, making it a hybrid conducting ceramic rather than a conventional semiconductor. It is primarily researched and deployed in high-temperature electrochemical devices, particularly as an interconnect material in solid oxide fuel cells (SOFCs) and as a component in oxygen permeation membranes, where its thermal stability, chemical compatibility with electrolytes, and ability to conduct both electrons and ions at elevated temperatures are essential. Compared to alternative interconnect materials, LaCrO₃-based systems offer superior oxidation resistance and better chemical compatibility with yttria-stabilized zirconia electrolytes, though its relatively lower electronic conductivity drives continued research into doped variants to enhance performance for next-generation energy conversion systems.
