Cadmium carbonate
Description
Cadmium carbonate (CAS 513-78-0), also referenced in some supplier catalogues as Kalcit or Chemcarb, is an inorganic cadmium salt used primarily as a precursor and catalyst component in industrial chemical processes.
It serves as a controlled source of cadmium ion in applications where direct use of more soluble cadmium compounds would complicate processing or handling. In electronics manufacturing, it acts as a starting material.
This compound is essential for producing cadmium-based pigments, phosphors, and semiconductor compounds used in specialty components. The mining and metals sector uses it as an intermediate in cadmium refining workflows.
Controlled decomposition yields cadmium oxide for further downstream processing. It also functions as a catalyst precursor in select organic synthesis reactions where thermal conversion to the oxide is part of the design.
Formulators working with cadmium-based stabilizers for PVC and specialty coatings may also source it as a raw material input. The material is supplied as a fine white to off-white powder for industrial use.
Technical grade is the standard commercial specification, with purity levels typically expressed as minimum assay by metal content. This ensures consistency across various manufacturing and chemical synthesis applications.
Packaging is available in small laboratory quantities through to bulk industrial quantities. All shipments are subject to applicable regulatory requirements governing cadmium compounds in the buyer's jurisdiction.
