· JVASP-116994· Zr2SiMo3

Zr2SiMo3 is a zirconium-silicon-molybdenum intermetallic compound belonging to the family of refractory metal silicides, combining the high-temperature stability of zirconium with the strength contributions of molybdenum and silicon. This material is primarily of research and development interest for extreme-environment applications where conventional superalloys reach their thermal or oxidation limits. The zirconium silicide matrix offers potential for aerospace propulsion systems, nuclear reactor components, and other high-temperature structural applications where weight efficiency and oxidation resistance are critical.
