Used as a catalyst support in dehydrogenation reactions, particularly in the production of propylene and other olefins. Also employed in solid oxide fuel cells due to its stability and ionic conductivity at high temperatures. Serves as a precursor in the synthesis of lithium-ion battery materials. Applied in ceramic and glass industries to improve thermal shock resistance and mechanical strength. Investigated for use in tritium breeding materials in nuclear fusion reactors because of its ability to retain and release tritium efficiently.
