Apperance: Characters peafowl green fine amorphous powder.

Nature: A malachite green color, fine particles of amorphous powder, its relative density of 3. 85. Insoluble in cold water and alcohol, soluble in acid and form the corresponding copper salts, soluble in aqueous solutions of cyanide, sodium hydroxide, ammonium salts and alkali metal carbonates to form copper complexes. When boiled in alkali metal carbonate solution, Brown copper oxide is formed, which is decomposed into black copper oxide, water and carbon dioxide at 200~220 ℃. Unstable in hydrogen sulfide atmosphere. The solubility in water was 0.0008%.

Use: Used in catalyst, pyrotechnic, pesticide, pigment, feed, fungicide, electroplating, anti-corrosion and other industries and the manufacture of copper compounds.

Safety: copper carbonate with dust, should avoid contact with the skin, eyes and other inhalation.
