· Sr2AsAu

Sr2AsAu is an intermetallic compound combining strontium, arsenic, and gold in a defined stoichiometric ratio. This is a research-phase material belonging to the family of ternary intermetallics, which are typically investigated for specialized electronic, magnetic, or structural applications where conventional alloys are insufficient. The compound's potential lies in fundamental materials science exploration—particularly for thermoelectric devices, quantum materials research, or high-performance electronic applications—though practical industrial deployment remains limited pending further characterization and scale-up feasibility.
