· JVASP-101264· K2SbAu

K2SbAu is an intermetallic compound containing potassium, antimony, and gold—a ternary system that belongs to the class of precious-metal-based intermetallics. This is a research-phase material with limited established industrial applications; it falls within the broader family of intermetallic compounds that are typically studied for their potential to combine the properties of constituent elements in ways conventional alloys cannot achieve. The compound's composition positions it as a candidate material for exploratory work in high-temperature applications, catalysis, or specialized electronic devices where the presence of gold and antimony might confer corrosion resistance or unique electronic properties.
