· Cr1 Au1 O2

Chromium gold oxide (CrAuO₂) is an experimental mixed-metal oxide semiconductor combining chromium and gold in a defined stoichiometric ratio. This compound belongs to the family of ternary oxides and is primarily of research interest for its potential electronic and photonic properties arising from the combination of transition metals with the noble metal gold. While not yet established in mainstream industrial production, materials in this chemical family are being investigated for applications in photocatalysis, gas sensing, and potentially optoelectronic devices where the unique electronic structure of mixed-valence metal oxides can be exploited.
