Basic Copper Carbonate 1)All kinds of grade 2)High purity and professional services 3)Competitive price English name: Cupric carbonate, basic    Copper carbonate hydroxide,  Cupric subcarbonate, Coppercarbonatebasic, Bremen blue, Bremen green, CoppercarbonatehydroxideMolecular formula: CuCO3•Cu(OH)2Molecular weight: 221.10Properties: amorphous powder green to blue or dark green monoclinic crystal. 200 °C decomposition. Soluble in acid and ammonia, dissolved in acid and the formation of the corresponding copper salt, soluble in cyanide, sodium hydroxide, ammonium and alkali metal carbonate aqueous solution to form copper complexes. Insoluble in cold water, almost insoluble in water and ethanol. Solubility in water of 0.0008%. The relative density of 4.0. Low toxicity. Irritant. Preparation of other copper. Solid phosphor activator. Pesticides. Seed treatment fungicides. Paint pigments, copper, tin plated copper alloy industry as additives, crude oil storage when the sorbent. The system is not yet out of pure copper carbonate, only synthesized CuCO3 • 2H2O and Cu (NH3) 2CO3 and other mixtures.Bright green malachite (CuCO3 • Cu (OH) 2 and blue azurite (Cu3 (CO3) 2 (OH) 2 is the natural existence of two basic copper carbonate. Basic copper carbonate by CuCO3: H2O ratio of different The existence of a dozen forms of compounds of industrial production, the formula for the CuCO3 • Cu (OH) 2 • XH2O.
