· JVASP-37704· PbAu3

PbAu3 is a lead-gold intermetallic compound representing a fixed stoichiometric phase in the Pb-Au binary system. This material is primarily of research and materials science interest rather than widespread commercial use, studied for its phase equilibrium behavior, crystal structure, and properties at the Pb-Au composition boundary. It may find niche applications in specialized electronics, jewelry alloys, or high-reliability solder systems where the unique properties of Au-Pb phases offer advantages over conventional lead-free alternatives, though cost and lead content typically limit adoption in modern applications.
