Co5O8
ceramic· JVASP-47502· Co5O8
Co₅O₈ is a mixed-valence cobalt oxide ceramic compound that exists as part of the cobalt oxide family, where cobalt exists in both +2 and +3 oxidation states. This material is primarily investigated in research and development contexts for electrochemical and catalytic applications rather than as an established engineering commodity. Its notable applications include energy storage devices (supercapacitors, battery electrodes), oxygen evolution catalysis for water splitting and fuel cells, and magnetic oxide systems—areas where its electrical conductivity and redox activity offer advantages over simpler cobalt oxide phases like CoO or Co₃O₄.

Regulatory Screening
Environmental
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.
