· Ba2 Sb1 Au1

Ba₂SbAu is an intermetallic compound semiconductor combining barium, antimony, and gold in a defined stoichiometric ratio. This is a research-phase material studied for potential thermoelectric and optoelectronic applications, representing the broader class of ternary intermetallics that can exhibit band-gap engineering and phonon-scattering properties useful in energy conversion and sensing. While not yet commercialized at scale, materials in this family are investigated for their ability to decouple electrical and thermal transport—a key advantage over conventional semiconductors for waste-heat recovery and high-efficiency power generation.

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.
