· Co4 Ni1 O8

Co₄Ni₁O₈ is a mixed-metal oxide semiconductor combining cobalt and nickel in a spinel or related crystal structure. This is primarily a research-phase material investigated for electrochemical and catalytic applications rather than a commercial engineering standard. The cobalt-nickel oxide family is notable for tunable electronic properties and catalytic activity, making it of interest in energy storage, water splitting, and environmental remediation applications where the synergistic effects of dual metal cations can enhance performance over single-metal oxide alternatives.

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.
