Cadmium oxide

Cadmium oxide (CdO, CAS 1306-19-0, EC 215-146-2) is an inorganic compound also known as cadmia, cadmium monoxide, or cadmiumoxide. It has no assigned E-code. It is classified under HS code 2825 90 60 and falls within the Salts & Minerals category.

In electronics manufacturing, cadmium oxide serves as a contact material in silver-cadmium oxide alloys, where it improves arc resistance and reduces welding in electrical switches. In plastics and polymer processing, it functions as a catalyst and stabiliser precursor, facilitating controlled reactions during compounding. The pulp and paper sector applies it in specific catalytic processes to regulate chemical conversions.

Cadmium oxide is supplied as an amorphous powder in technical and industrial grades. As a substance of very high concern (SVHC) under REACH, procurement requires confirmed authorisation and compliance documentation prior to supply. Buyers should confirm regulatory status in their jurisdiction before ordering, as restrictions apply across EU member states.
