HfAu9
metal· JVASP-101462· HfAu9
HfAu9 is an intermetallic compound in the hafnium–gold system, representing a specific stoichiometric phase combining a refractory metal (hafnium) with a noble metal (gold). This material is primarily of research and development interest rather than established industrial production, with potential applications leveraging the combined properties of high-temperature stability from hafnium and corrosion resistance from gold.
