· JVASP-30291· Co3NiO8

Co3NiO8 is a mixed-metal oxide ceramic composed of cobalt and nickel oxides. This material belongs to the spinel or layered oxide family and is primarily investigated in electrochemistry and energy storage research rather than established high-volume industrial applications. It is notable for its potential in catalytic and energy conversion applications, where the synergistic properties of cobalt and nickel oxides offer advantages in oxygen evolution reactions, water splitting, and battery electrode materials compared to single-metal oxide alternatives.

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.
