· Sb8 Au4

Sb8Au4 is an intermetallic compound combining antimony and gold in a defined stoichiometric ratio, belonging to the semiconductor/metallic phase family with potential applications in thermoelectric and electronic device research. This material represents an experimental composition within the Au-Sb phase system, studied primarily in research settings for its potential in energy conversion and solid-state electronics where the combination of gold's conductivity and antimony's thermoelectric properties may offer benefits. Engineers would evaluate this compound for niche applications requiring precise phase control and the unique electronic structure that intermetallic compounds provide, though it remains primarily a laboratory material rather than an established commercial alloy.
