· Ba2SbAu

Ba2SbAu is an intermetallic compound combining barium, antimony, and gold in a defined stoichiometric ratio. This material belongs to the family of ternary intermetallics and is primarily of research and development interest rather than a widely commercialized engineering material. Ba2SbAu and similar ternary metal compounds are investigated for potential applications in thermoelectric devices, electronic components, and advanced materials requiring specific crystallographic structures and electronic properties.
