CoAsO2N

CoAsO₂N is an experimental ceramic compound combining cobalt, arsenic, oxygen, and nitrogen elements, representing a quaternary nitride-oxide system of primarily research interest. While not yet established in mainstream engineering applications, materials in this compositional family are investigated for potential use in catalysis, semiconductors, and high-temperature ceramics where multi-element metal nitrides and oxides offer tailored electronic and thermal properties. The arsenic content and complex phase chemistry make this compound notable in materials science research but also require careful handling and assessment of toxicity implications for any practical applications.
