· Co5 O8

Co₅O₈ is a mixed-valence cobalt oxide ceramic compound belonging to the family of transition metal oxides, where cobalt exists in both +2 and +3 oxidation states. This material is primarily of research and developmental interest rather than a widespread industrial standard, with potential applications in electrochemistry, catalysis, and energy storage where its redox activity and ionic conductivity are valuable. Compared to single-phase cobalt oxides like CoO or Co₃O₄, Co₅O₈'s mixed-valence structure offers potential advantages for catalytic processes and battery electrode materials, though practical engineering adoption remains limited pending further characterization and scalability development.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
