metal

· Na2SbAu

Na2SbAu is an intermetallic compound combining sodium, antimony, and gold in a fixed stoichiometric ratio. This material is primarily of research interest rather than established industrial use, belonging to the family of complex metallic alloys and intermetallics that are studied for specialized electronic, catalytic, or structural properties. The incorporation of gold and antimony suggests potential applications in thermoelectrics, catalysis, or advanced electronic devices, though practical deployment remains limited to experimental and laboratory settings.
