RbAu is an intermetallic compound composed of rubidium and gold, representing a rare binary metal system with limited commercial development. This material exists primarily in research and materials science contexts, where it is studied for fundamental understanding of intermetallic phase behavior, crystal structure, and physical properties rather than established industrial applications. The rubidium-gold system is of academic interest for exploring metal-metal bonding, thermodynamic stability, and potential applications in specialized electronics or experimental alloys, though practical use remains negligible due to cost, reactivity of rubidium, and lack of performance advantages over conventional alloys.
