YSi₂ is an intermetallic ceramic compound belonging to the rare-earth silicide family, combining yttrium with silicon in a defined stoichiometric ratio. It is primarily investigated as a high-temperature structural material and coating constituent for extreme-temperature applications where conventional ceramics or metals reach their limits. The material is notable for its potential use in aerospace propulsion systems, thermal barrier coatings, and nuclear applications, though it remains largely in research and development rather than high-volume production.
