· Co4 N2

Co4N2 is a cobalt nitride semiconductor compound that combines cobalt metal with nitrogen to form a hard, refractory material. This material belongs to the transition metal nitride family, which are of significant research interest for their potential in catalysis, hard coatings, and electronic applications due to their combination of metallic and ceramic properties. Co4N2 remains largely in the experimental and developmental stage, with applications being explored primarily in electrocatalysis (particularly for hydrogen evolution and oxygen reduction reactions), wear-resistant coatings, and potential semiconductor devices where the material's hardness and chemical stability offer advantages over conventional alternatives.

Export Control

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.
