· Au1 Ni4 Y1

Au1Ni4Y1 is an intermetallic compound combining gold, nickel, and yttrium in a 1:4:1 stoichiometric ratio, belonging to the family of ternary metallic compounds. This material is primarily of research and developmental interest rather than established commercial production, with potential applications in high-temperature structural applications, catalysis, or electronic materials where the combination of noble metal (Au), transition metal (Ni), and rare-earth element (Y) properties might offer advantages in corrosion resistance, thermal stability, or electronic functionality.
