Cadmium carbonate

Cadmium carbonate (CAS 513-78-0, EC 208-168-9, formula CdCO3) is an inorganic cadmium salt also referenced under the names cadmium monocarbonate and Caswell No. 134A. It carries no E-code designation and is classified within the Salts & Minerals category.

In electronics manufacturing, cadmium carbonate serves as a precursor in the production of cadmium-based semiconductors and electrode materials, decomposing under heat to yield reactive cadmium oxide. In catalytic applications, it functions as a catalyst component or precursor where controlled cadmium ion release influences reaction selectivity in specific chemical synthesis processes.

Cadmium carbonate is supplied as a milky white powder and is subject to REACH regulation (Regulation EC 1907/2006) given its classification as a hazardous cadmium compound, requiring documented downstream use justification. Procurement professionals should confirm SDS compliance and applicable restriction entries under REACH Annex XVII before ordering.
