Cupric carbonate basic, naturally occurring as malachite, is a green, insoluble basic copper salt. Its structure combines carbonate and hydroxide ions, exhibiting amphoterism by reacting with both acids and strong bases. This compound acts as a precursor for synthesizing copper oxides, catalysts, and pigments.
55% copper carbonate basic represents an ultra-high-purity grade with near-stoichiometric copper content, approaching the theoretical maximum. This exceptional purity minimizes residual hydroxides or carbonates, enhancing thermal decomposition efficiency for producing high-purity copper oxide.
54% copper carbonate basic represents a high-purity grade with precisely controlled stoichiometry, ensuring optimal copper ion bioavailability. This specification exceeds typical commercial grades, offering enhanced efficacy in agricultural fungicides where maximum copper delivery is critical.
Copper carbonate basic features a controlled particle size distribution averaging 44 microns, achieved through precision milling. This fine grade offers enhanced reactivity and dispersion efficiency in specialized applications, including high-performance catalysts for low-temperature CO oxidation and conductive polymer composites.
Carbonate Copper Basic typically refers to industrially produced particles ranging from 1–20 μm, optimized for bulk applications. Its consistent particle distribution ensures uniform dispersion in paints and coatings, providing durable green pigmentation with excellent UV resistance.
Dicopper carbonate dihydroxide exhibits amphoteric behavior, reacting with acids to form soluble copper salts and with strong bases to produce cuprite (Cu₂O). It serves as a flotation agent in copper ore concentration, selectively binding to sulfide minerals. In catalysis, it facilitates alcohol oxidation reactions under mild conditions.
