· JVASP-155641· NaSi2Au2

NaSi₂Au₂ is an intermetallic compound combining sodium, silicon, and gold—a material from the broader family of gold-based intermetallics that are primarily of research interest rather than established industrial use. This compound belongs to the category of lightweight intermetallic phases and is investigated for potential applications in advanced materials research, particularly in studying electronic and structural properties of gold-silicon-alkali metal systems. While not yet deployed in mainstream engineering applications, materials in this family are explored for their potential in electronic devices, catalysis, and specialty alloy development where unusual phase stability or electronic behavior may offer advantages over conventional alloys.

Export Control

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.
