Y1 Au1
semiconductor· Y1 Au1
Y1 Au1 is a binary intermetallic compound composed of yttrium and gold in a 1:1 stoichiometric ratio. This material belongs to the rare-earth–noble-metal intermetallic family and is primarily of research interest rather than established in high-volume commercial production. Potential applications span high-temperature materials research, advanced electronics, and catalysis, where the combination of yttrium's high melting point and gold's chemical stability may offer unique properties; however, its rarity and cost typically limit adoption to specialized scientific and aerospace contexts.
