Cuprous Oxide CuO powder:

Copper oxide states. Copper can be found in both +1 or +2.

Copper (II) Oxide is an organic substance with CuO. It is a dark copper oxide, somewhat amphiphilic but slightly hygroscopic. Copper oxide has a weak base.

Black copperoxid is CuO. Red copperoxid Is Cu2O.

Copper oxide can be almost insoluble when mixed with water and alcohols. However, copper oxide disintegrates slowly in ammonia but fast in ammoniumcarbonate solution. The alkali-metal cyanides and strong acids dissolve it quickly.

Copper Oxide is used primarily to produce rayon, ceramics glaze and enamel and petroleum desulfurizes. Pesticides are also produced.

Cu oxideCuO is made on large scales by pyrometallurgy. It is an intermediate step in the extraction of copper from ore. An aqueous mixture containing ammonium carbonate (ammonia) and oxygen is applied to the ore. This results in copper (I) and (II), amino complexes that are then extracted from the solid. The steam is used to decompose these complexes and produce CuO.

The precursor to many copper-containing products like ceramics and wood preservers is cupric oxide. Cupric oxide is found in a variety of ways, including ingestion, skin contact and inhalation. Copper(II), oxide nanoparticles (NPCuO) can be used as industrial antimicrobials in textiles, paints, and to act as catalysts for organic synthesis. You can also make them from electronic scraps. Because cupric oxide is toxic, muta and generates reactive oxygen compounds, it can cause potential health and environmental problems.

Performance Copper Oxide CuO Pulp:

Copper oxide is not soluble or soluble with water and alcohol. It can also be soluble in acids, ammonium chloride, potassium cyanide and acid. The copper oxide can react with many bases and slowly dissolves in ammonia solutions. The main uses of copper oxide are to make rayon, ceramics glaze and enamel as well batteries, petroleum desulfurizes. Insecicides, hydrogen production catalysts, and other green-colored glass.

What is Copper Oxide CuO Powder made of?

There are many methods for industrial copper oxide production

1. Method of copper powder oxidation

Copper ash, copper slag are used as raw materials. They then undergo preliminary oxidation with coal gas. The heat is to evaporate moisture from the materials and remove organic impurities. It is then naturally cooled and pulverized to make crude copper oxide. After adding the crude copper dioxide to the reactor, it is heated and stirred until the ratio of liquid to sulfuric acid doubles. At that point, the pH value of the solution will be 2 or 3. Under heating and stirring, copper oxide can be added to the reactor. After that, it is washed in hot water with no iron or sulfate. Centrifugal separation is followed by drying and oxidation roasting at 350°C for 8 hours. Cooling, crushing to 100 meshes then oxygenation in an oven to produce copper oxide powder.

2. Nitration copper wire, copper powder

The copper wire and copper powder should be dissolvable in 6mol/L Natric Acid to prevent excess copper. To remove iron hydroxide precipitate from the solution, raise the pH to 3-4. Mix the solution with 10% (massive) sodium carbonate to bring it to boiling. After alkaline salt has precipitated, remove the supernatant and wash well with water. Filter it then dry. The dried basic copper carbonate is heated and decomposed into black copper oxide powder under a small fire with sufficient stirring: CuCO3*Cu(OH)2=2CuO+CO2|+H2O

Once no carbon dioxide remains, decomposition will be complete.

3. Thermal decomposition of copper nitrate

Dilute nitric acids is used to dissolve the electrolytic copper. It’s then evaporated on a water bath to dry it, before being heated very slowly in a dehydrator from 90 to 120degC. After the formation of soft basic salt, it must be boiled with water and filtered to dry. Next, heat it to 400 for most of the sodium to evaporate. Finally, crush it to make oxidation copper. You can further enhance the process by pulverizing the product again and heating it at 700degC for about an hour. Then, place the product in a desiccator to cool.

4. Conductive water dissolution method

Use conductive water to dissolve high-purity copper Nitrate. Filter the solution, then add extra high-purity NaH3*H2O. After filtering, use high purity nitric to neutralize the filtrate. Filter, use conductive water to wash the filtrate once, add high-purity ammonium to precipitate copper carbonate. After drying, turn off heat and dry at 200degC.

5. Method for thermal decomposition copper carbonate

For complete dissolution, place copper wire or powder in a fume hood containing as much 6mol/L Nitric Acid as you can. Filter the solution if it is too opaque. To create black basic salt precipitation, sodium carbonate is boiled with the copper solution. After the solid settles completely, drain the excess liquid and filter it. Dry by decantation. Place it in an evaporating tray and heat on a small flame with enough stirring to turn it into copper oxide.

Copper Oxide Uses:

Copper(II) Oxide is an important product of copper mining. It’s the base for production of other copper salts. Many wood preservers, for example, are made from copper oxide.

Cupric oxide is used to make ceramics in the colors blue, red and green. Sometimes, gray, pink or black glazes are also produced.

Also, it is not recommended to be used in livestock feeds as an dietary supplement. Copper is not absorbed due to its low bioactivity.

It can also be used for welding copper alloys.

An early form of the Edison-Lalande type battery included a copper dioxide electrode. Copper oxide could also be used to make a type of lithium battery.

Copper(II). Oxide can also be used in catalysis and superconductivity; ceramics; catalyst carriers; electrode activity material;

glass, colourants of porcelain, polishing agent for optical glasses, oil to desulfurize; propellant rocket fuel speed catalyst.
