· JVASP-44685· Co4NiO8

Co₄NiO₈ is a mixed-metal oxide ceramic composed of cobalt and nickel in an ordered spinel or related crystal structure. This material family is primarily investigated in research contexts for electrochemical and catalytic applications, where the combination of cobalt and nickel oxides provides synergistic redox activity and ionic conductivity. Its notable appeal versus single-metal oxide alternatives lies in the potential for enhanced catalytic performance and tunable electronic properties through compositional control of the Co:Ni ratio.

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.
