· JVASP-37270· Sm2Au2O5

Sm2Au2O5 is a rare-earth oxide ceramic compound containing samarium and gold, belonging to the family of mixed-valence oxide ceramics. This is primarily a research and development material studied for its potential electrochemical and thermal properties rather than a widely commercialized engineering ceramic. The inclusion of precious metal gold combined with rare-earth samarium makes this compound of interest for specialized applications in high-temperature catalysis, solid-state electronics, and advanced energy conversion systems where unique chemical stability and electronic properties are advantageous.
