· Ba8Au5.14Si39.51

Ba8Au5.14Si39.51 is an intermetallic compound belonging to the barium-gold-silicon family, representing a research-phase material rather than an established commercial alloy. This ternary compound is of interest in thermoelectric and advanced materials research, where the combination of heavy barium atoms, noble metal gold, and semiconductor-grade silicon can influence phonon scattering and electronic transport properties. Engineers would evaluate this material in niche applications requiring specialized thermal or electrical behavior at reduced scales, though current industrial adoption remains limited pending further characterization and processing development.

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.
