CoO
ceramic· CoO
Cobalt oxide (CoO) is a ceramic compound that exists as a rock-salt cubic structure at room temperature, valued for its electrical and magnetic properties. It is used primarily in high-temperature applications, catalysis, pigmentation, and as a precursor material in battery and electronics manufacturing, where its stability and electrical conductivity make it preferable to softer oxides. Engineers select CoO when thermal stability, chemical inertness, or specific electronic behavior is required in oxidizing environments.

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.
