Basic copper carbonate is also called copper rust and copper rust, and its chemical formula is Cu? (oh) CO？ , is a substance produced by the reaction of copper with oxygen, carbon dioxide and water vapor in the air. Heating in air will decompose into copper oxide, water and carbon dioxide, and dissolve in acid to generate corresponding copper salts.

Its use:

1, used in catalyst, fireworks, pesticide, pigment, feed, bactericide, electroplating, anticorrosion and other industries and the manufacture of copper compounds.

2. Used as analytical reagent and pesticide.

3. Used in organic catalysts, fireworks manufacturing and pigments. In agriculture, it is used as a preventive, insecticide and antidote for phosphorus poisoning, and also as a fungicide for seeds; Mixing with asphalt can prevent livestock and wild rats from biting saplings; Used as additive of copper in feed, dealkalizing agent in crude oil storage and raw material for producing copper compounds. It can also be used for electroplating, anticorrosion and analytical reagents.

4. Paint pigments, fireworks, pesticides, seed treatment fungicides, preparation of other copper salts and solid phosphorus activators.
