Character:The peacock green tiny amorphous powderInsoluble in water and alcohol. Soluble in acid, ammonia and potassium cyanide
Stable at room temperature under normal pressure
Avoid material acid.Insoluble in cold water and alcohol, decomposition in the hot water, soluble in
acid and copper salt accordingly.Soluble in cyanide and ammonia, ammonium salt and alkali metal carbonate in
aqueous solution, forming the complex of copper.Boil in alkali metal carbonate solution, the formation of brown copper oxide.The hydrogen sulfide instability.Heated to 200 ℃ decomposition black copper oxide, carbon dioxide and water.Instability in the hydrogen sulfide gas.In the water solubility of 0.0008%.Copper carbonate dust resistance, should avoid contact with skin and eyes and
Insoluble in water, soluble in ammonia water generated in the copper ammonia
complex ion.Decompose when heated to 220 ℃.Composition is 2:1 alkali type copper carbonate crystallization for sky blue
powder.If long placed in the air, moisture absorption and release of carbon dioxide,
slowly become a 1:1 alkali type copper carbonate, insoluble in water, but
soluble in ammonia water to form a copper ammonia complex ion.
1. Copper sulfate method. Reaction equation:
2. Copper nitrate method.Methods: electrolytic copper and nitric acid generated after copper nitrate,
reacts with sodium carbonate and sodium bicarbonate mixture generated alkali
type copper carbonate, precipitation after washing, separation, dehydration,
drying, alkali type copper carbonate was finished.
3. Copper nitrate and sodium carbonate as raw material, the preparation of
amount of substance such as trihydrate copper nitrate and sodium carbonate
solution, mixing, stirring, at this point that generate blue-green colloidal
precipitation, continue stirring at room temperature, the crystal material can
generate, filtration, drying in the air. Composition for the product can be got.
Or can also be used for five copper sulfate hydrate or a hydrated copper acetic
acid and potassium carbonate as raw material was also the purpose of the
1.Used in organic catalysts, fireworks, and pigments. Role in agricultural plants
smut preventing agent, phosphorus pesticides and poison the antidote, mixed with
asphalt can prevent the chip and rats chew saplings; Used in feed for copper
additive, as dealkalization agent in oil storage and production of copper
compound materials. Can also be used in electroplating, antisepsis and
2. Used as feed additives, cattle and other ruminants of copper carbonate
absorption utilization rate is higher than other inorganic copper. But due to
the high cost, make its application is limited.
3. Used as analytical reagent. Used for copper salt preparation, preparation of
paint pigments and fireworks raw materials. As an activator phosphors, seed
4. To a copper alloy, silver plated copper tin alloy and the confecting of
oxidation of steel.
Storage and transportation
1. Store in a cool, ventilated, dry warehouse.
2. We should pay attention to moistureproof. Bags against breakage.
