HeAu3
metal· JVASP-126893· HeAu3
HeAu3 is an intermetallic compound composed of helium and gold, representing an exotic metal-helium system that exists primarily in specialized research and high-pressure physics contexts rather than conventional engineering applications. This material belongs to the family of helium compounds that form under extreme conditions, and is notable for its unusual atomic interactions between the noble gas helium and the precious metal gold. HeAu3 remains largely experimental; its potential significance lies in advancing fundamental understanding of intermetallic bonding, extreme-condition materials behavior, and novel phase diagrams at high pressures.
