· JVASP-59061· Rb5Au3O2

Rb5Au3O2 is an oxide ceramic compound combining rubidium, gold, and oxygen—a rare mixed-metal oxide that exists primarily in research and materials science contexts rather than established industrial production. This compound belongs to the family of noble metal oxides and represents an experimental material of interest for understanding unusual chemical bonding and crystal structures involving precious metals. While not yet deployed in mainstream engineering applications, materials in this class are investigated for potential uses in catalysis, electrochemistry, and specialized optical or electronic applications where the combination of alkali metals with noble metals offers novel properties.
