· Ce4 Sm4 O14

Ce₄Sm₄O₁₄ is a rare-earth oxide ceramic compound combining cerium and samarium oxides in a mixed-valence structure. This material belongs to the family of rare-earth oxides used primarily in advanced ceramics and functional materials research, where it is investigated for applications requiring high-temperature stability, ionic conductivity, or catalytic properties. The dual rare-earth composition makes it notable for potential use in solid oxide fuel cells, oxygen ion conductors, and catalytic applications where the synergistic effects of multiple lanthanide elements enhance performance compared to single rare-earth oxide alternatives.
