Copper Carbonate 95%
COPPER CARBONATE BASIC available in 50g, 150g, 250g, 500g, 1500g.
Molecular Formula: CuCO3 Cu (OH) 2
Copper carbonate is acid soluble, forming copper salt, cyanides, sodium hydroxide and ammonium salts. By reacting with hydrogen sulfide, it produces copper sulfide. Due to its lower toxicity, it is safe to use. Depending on the conditions and the recipe, it can produce a green, blue-green or copper-red color, so it can be used as a painting agent.
- wood impregnation,
- in PCB systems for cyanide-free electroplating,
- for electroplating decorative materials (Mg-Al alloy), auto parts, machine parts, jewelry, steel, dairy equipment, etc.
- pottery and ceramics,
- as a glaze dye,
- organic catalyst,
- in the production of fireworks.
Aesthetic and practical use
Mined as malachite, the beautiful specimens of basic copper carbonate are popular hounds and jewelry. More importantly, malachite, along with oxide and sulphide ores, can be converted into valuable metallic copper. The process involves pulverization, sorting, conversion to soluble sulfate and electrolysis, resulting in a very pure product.
Used to form copper salts
Copper carbonate is easily converted into many important industrial copper salts. Copper carbonate itself is a salt of a very weak carbonic acid. The addition of a stronger acid replaces the carbonic acid, producing the desired salt as well as water and carbon dioxide gas. For example, copper carbonate plus acetic acid (vinegar) produce copper acetate, water, and carbon dioxide. Other common copper salts that can be made in this way include copper sulfate (blue vitriol), copper chloride, and copper nitrate.
Used in pigments and dyes
Pure copper carbonate, free from alkali, is mint green in color. The presence of an alkaline component adds a shade of blue. Individually or in combination, they are used as pigments to add color to paints and varnishes. The exact blue-green color depends on the proportion of the ingredients. Copper carbonate is also used to produce color in pyrotechnics such as fireworks, and in ceramic glazes.
Small amounts of copper carbonate are used in animal feed and fertilizers as a source of essential copper. One example is its use in preventing the "stink of wheat". Thus, copper carbonate is used to a limited extent in the coating of agricultural seeds. Copper sulfate or copper carbonate can be used to control aquatic weeds as most of the water is slightly acidic. Finally, copper carbonate can be used to prepare alkaline copper quaternary ammonia compounds for wood treatment.
