· Mg4 Co4 O8

Mg4Co4O8 is a mixed-metal oxide semiconductor combining magnesium and cobalt in a spinel or related crystal structure. This is primarily a research-phase material explored for its potential in energy storage, catalysis, and electronic device applications where the combined properties of these transition metal oxides offer unique electrochemical or magnetic characteristics. While not yet widely commercialized, materials in this family are of interest to researchers developing next-generation batteries, supercapacitors, and catalytic systems where cobalt oxide provides activity and magnesium contributes structural stability and cost advantages.

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.
