Description

Cadmium Carbonate is an inorganic salt of cadmium and carbonic acid, widely recognized for its utility as a precursor in the synthesis of other cadmium compounds. This high-purity material is essential for applications requiring controlled cadmium ion release and consistent chemical performance. It serves as a critical raw material for manufacturers in the ceramics, pigment, and specialty chemical industries, where precise formulation is paramount.

Application

• Pigment Manufacturing: Acts as a key intermediate in the production of cadmium-based pigments (e.g., cadmium yellow, red) for plastics, ceramics, and artists' colors.
• Ceramic Glazes & Glass: Used to impart specific colors and properties to ceramic glazes, enamels, and specialty glass formulations.
• Chemical Synthesis: Serves as a fundamental starting material for producing other cadmium salts, such as cadmium oxide, sulfide, and halides.
• Electroplating: Employed in specific electroplating baths for depositing cadmium coatings, though this application is highly regulated.
• Catalyst Production: Utilized in the preparation of catalysts for certain organic synthesis and hydrogenation reactions.
• Laboratory & Research: Used as a reagent in analytical chemistry and materials science research.
• Stabilizer for Polymers: Functions as a heat and light stabilizer in specific PVC and other polymer formulations.
