· JVASP-21931· NaSiAu3

NaSiAu3 is an intermetallic compound combining sodium, silicon, and gold in a fixed stoichiometric ratio, belonging to the family of ternary metal systems. This is primarily a research material rather than an established commercial alloy; such sodium-gold intermetallics are of academic interest for studying unusual bonding behavior and phase relationships in alkali-metal systems, though practical engineering applications remain limited due to sodium's high reactivity and the material's specialized synthesis requirements.
