Basic copper carbonate was blue or green color depending on the composition may be, for the fine particles of amorphous powder, its density is 3.85. Insoluble in cold water and alcohol, and the formation of the corresponding acid soluble copper, soluble cyanide, sodium hydroxide, ammonium and alkali metal carbonate aqueous solution to form copper complexes. In boiling alkali metal carbonate solution, the resulting brown copper oxide, at 200 ℃ broken down into a black copper oxide. Instability in the atmosphere of hydrogen sulfide. Basic copper carbonate by CuCO3: H2O ratio exists in a dozen different forms of the compounds. Industrial production, the formula for the CuCO3 · Cu (OH) 2 · xH2O. Solubility in water of 0.0008%, the decomposition temperature of 200-220 ℃. Low toxicity.
Thermal decomposition: CuCO3 = CuO + CO2 ↑
Dynamic calciner is the hot air with copper carbonate powder mixed in space. Powder suspension and heat to break down into contact with copper oxide.
The calcined calciner fast, continuous operation, product stability; operating environment environmental protection. Designed with energy-saving devices, reduce operating costs. Far-sighted decision-makers want to use.
