Er2 Ag1 Ru1

Er₂Ag₁Ru₁ is an intermetallic compound combining erbium (a rare earth element), silver, and ruthenium in a fixed stoichiometric ratio. This is a research-stage material rather than an established commercial alloy; compounds of this type are typically investigated for their electronic, magnetic, or catalytic properties at the intersection of rare earth metallurgy and transition metal chemistry. The material family shows potential in applications requiring combinations of rare earth magnetism, noble metal stability, and transition metal catalytic or electrochemical behavior, though real-world engineering use remains limited pending further characterization and scale-up.
