· Na3In2Au

Na3In2Au is an intermetallic compound combining sodium, indium, and gold—a ternary alloy that falls outside conventional engineering metals and is primarily studied in materials research rather than established industrial production. This compound belongs to the family of complex intermetallics and is of interest for fundamental studies of phase stability, electronic structure, and potential applications in specialized high-performance or functional material systems. Its practical adoption remains limited, making it most relevant to researchers exploring novel alloy systems, solid-state chemistry, or emerging technologies where cost and processability are secondary to unique material properties.
