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.
