High Purity Copper Oxide CuO powder CAS 1317-38-0, 99.9% |

Cuprous Oxide CuO Powder:
Copper oxide states: There are two states of oxidation for copper: +1 and +2.
The chemical formula for copper(II), CuO, is An inorganic substance. It is an oxide of black copper. It’s slightly amphiphilic. Copper oxide has a weak base.
Black Copper Oxide is CuO and red Copper Oxide Cu2O.
Copper oxide is insoluble in water and alcohols. Copper oxide dissolves slowly but rapidly in ammonia solutions, while it dissolves quickly in ammonium sulfate solutions.

The copper oxide can be used in the production of rayon, ceramics glazes and enamels, batteries, pesticides as well as petroleum desulfurizers.
Cu oxideCuO is produced in large quantities by pyrometallurgy. This is a process of extracting copper ore. The ore mixture is treated with a solution of ammonium, ammonia and ozone to extract copper (I), copper (II), and amino complexes. Steam is used for the decomposition of these complexes to produce CuO.
The precursor of cupric oxide can be found in many copper-containing materials, including wood preservatives or ceramics. Cupric oxide is commonly ingested, inhaled and dermally exposed by adults. Copper(II), Oxide Nanoparticles (NPCuO), have many industrial applications. They are antimicrobial agents for textiles and paints as well as catalysts for organic synthesis. The particles may be created from electronic scrap. The toxic and muta-producing particles in cupric oxide could pose health and environment concerns.

Copper Oxide CuO powder:
Copper oxide is not soluble with water or ethanol. However, it is soluble with acid, ammonium cyanide and chloride. It is slowly dissolved in ammonia solutions and reacts with strong bases. Copper oxide can be used to produce rayon, ceramics glazes and enamels, batteries, insecticides (for petroleum desulfurization), catalysts, green glasses, etc.

What is Copper Oxide Powder?
There are many methods for industrial production of Copper Oxide
1. Copper powder oxidation process
Using raw copper ash or copper slag, the materials are heated and roasted using coal gas to perform a preliminary oxidation. This removes moisture and organic contaminants from the raw materials. The primary oxide produced is cooled naturally and then pulverized to produce crude copper oxide. After adding the crude copper oxide to a reactor that has been pre-installed 1:1 sulfuric acid and heating and stirring the liquid, the reaction is completed when the pH level is between 2 and 3 and the relative density is doubled. Then, after clarification, the iron shavings will be added and heated and stirred until there are no more sulfate or iron. After centrifugal separating, drying and oxidation roasting (450degC) for 8hours, cooling, then crushing to 100mesh, the copper oxide powder can be obtained.
2. Nitration of Copper Wire or Copper Powder
To keep the copper excess, dissolve the copper powder or wire in 6mol/L Nitric Acid. Heat the solution up to pH 3-4, to remove the precipitate of iron hydroxide, and then add 10% (mass), sodium carbonate. Bring to boil. After the alkaline solution is precipitated, remove the supernatant and wash it thoroughly with water. Filter, dry, and discard. 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
The decomposition process is complete once no carbon dioxide is generated.
3. Thermal decomposition using copper nitrate
It is then slowly heated from 90degC up to 120degC in a dehydrator. After the soft salt has been formed, it’s boiled with water, filtered, and dried. It’s then slowly heated at 400 degrees Celsius to remove the nitric-acid. The reaction can be completed by pulverizing the product, heating it at about 700degC (for 1 hour) and cooling it in a desiccator.
4. Conductive water dissolution method
Use high-purity acid nitric in order to neutralize filtrate and precipitate copper hydroxide. Filter, wash with conductive water once, add nitric acids to dissolve precipitate, and add high-purity Ammonium Carbonate to precipitate Copper Carbonate. Wash, spin dry, bake at 200degC until dry, then burn at 450-550degC between 3-4 hours to get Spectral Pure Copper Oxide:
5. Copper Carbonate Thermal Decomposition Method
In a fumehood, dissolve copper powder and copper wire using as little nitric as possible (6mol/L). The solution must be filtered if it’s opaque. In addition, the copper nitrate is mixed with sodium carbonate and then boiled in order to create black basic sal precipitation. Once the solid settles out, drain the liquid and wash it thoroughly. Filter, then decant the solution to dry. Heat it over a low fire and stir it enough to convert it into copper dioxide.

Copper Oxide Uses:
Copper(II), as a by-product of copper mining is a starting point for producing other copper salts. Copper oxide, for example, is the starting point of many wood preservatives.
As a ceramic pigment, cupric dioxide is used to make blue, red, green and gray glazes.
Also, it’s incorrectly added to animal feed. A low bioactivity means that copper is only absorbed in a negligible amount.
Also used in welding copper alloys
An early battery called the Edison-Lalande was equipped with a copper oxide electrolyte. The copper oxide electrode was also used for a lithium-ion battery type.
Copper(II) Oxide can be used in catalysis; superconductivity; ceramics; as catalyst carriers; and electrode activity materials.
Oil of desulfurized, glass colorants, optical glasses polishing agent; rocket fuel speed catalyser.

Conditions of storage for Copper Oxide CuO powder:
Copper Oxide CuO should not be exposed air and should be stored in a dry, cool, and sealed environment.
