Basic copper carbonate 
 Basic copper carbonate, also known as copper carbonate, was malachite green color, fine particles of amorphous powder, its density is 3.85. Do not dissolve in cold water and alcohol, soluble in acid and the formation of the corresponding copper salt, soluble in the aqueous solution of sodium hydroxide, ammonium and alkali metal carbonate and the formation of copper complexes. When boiled in alkali metal carbonate solution, generating a brown copper oxide, and decomposed into black copper oxide at 200 ℃. Instability in the hydrogen sulfide atmosphere. Basic copper carbonate a dozen forms of the compounds according to the different ratio of CuO: CO2: H2O. Industrial production, its molecular formula is the CuCO C (OH) 2 · xH2O. Solubility in water, 0.0008%, the decomposition temperature of 200-220 ℃. Low toxicity. Second, the formula: CuCO C (OH) 2 · xH2O 

 Third, the Application 
 Catalysts, pigments, fireworks, pesticides, the same applies to wood preservatives and wood carbonization.
