Solubility
Soluble in concentrated solutions of ammonium salts, dilute acids.;Soluble in acid;Insoluble in water
Application
Cadmium carbonate is primarily used as a raw material for creating pigments utilized in ceramics and frits, as well as for producing cadmium salts. This white, powdery solid, with a density of 4.258 g/cm³, decomposes upon heating below 500°C. While it remains insoluble in water and liquid ammonia, it reacts with acids where it becomes soluble. Additionally, cadmium carbonate plays a significant role as a reagent, specifically serving as a catalyst. Its applications extend to being an intermediate in the production of polyesters, serving as a flux for glass pigments, and being involved in the creation of organic catalysts, plastic plasticizers, and stabilizers.
