· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
