· Ru4 O8

Ru₄O₈ is a mixed-valence ruthenium oxide ceramic compound belonging to the family of transition metal oxides with potential semiconducting properties. This material is primarily of research interest rather than established industrial use, being investigated for applications requiring novel electronic or catalytic behavior in oxygen-rich environments. Its significance lies in the ruthenium oxidation states and crystal structure, which researchers explore for energy storage, catalysis, and electronic device applications where conventional oxides are insufficient.
