· JVASP-50622· Rb3ErO3

Rb3ErO3 is an inorganic ceramic compound composed of rubidium, erbium, and oxygen, belonging to the class of rare-earth oxides. This material is primarily of research interest rather than a mature commercial product, studied for its potential in solid-state chemistry and advanced ceramic applications. The rare-earth erbium component makes this compound relevant to photonic, luminescent, and specialized electronic applications where lanthanide-containing ceramics offer unique optical and electrical properties.
