· JVASP-50896· Rb3SbO3

Rb₃SbO₃ is an inorganic oxide ceramic compound composed of rubidium and antimony oxides, belonging to the family of rare-earth and alkali-metal antimonates. This material is primarily investigated in research contexts for applications requiring specific ionic conductivity, optical, or structural properties rather than being widely commercialized in mainstream engineering. The compound is notable within the materials science community for its potential in solid-state ionic conductors, photocatalytic systems, and specialized ceramic applications where rubidium's alkali properties combined with antimony's redox chemistry offer advantages over more conventional ceramic oxides.
