What is copper oxide?
Copper is a reddish metal with a very high electrical and thermal conductivity, only surpassed by the thermal conductivity of gold and silver. Copper has a low oxidation state in most compounds (+2 is usual). There are also some compounds with an oxidation state of +1. In the presence of air, the initial salmon-red color is converted into violet-red because of the creation of cuprous oxide (Cu2O). Then it blackens itself by producing cupric oxide (CuO) and, continuously exposed to moist air, forms an adherent layer carbonate raincoat that is poisonous. It is easily attacked by halogen elements in the occurrence of moisture, as dry bromine and chlorine have no effect, although fluoride attacks at a temperature higher than 500 °C. Among its mechanical properties, its exceptional deformability and flexibility stand out.
Types of Copper Oxide
Oxygen can be combined with copper in diverse ways to produce two compounds: copper oxide (I), a reddish powder, and copper oxide (II), a black powder. These compounds are also found in nature as minerals; both copper oxides are used in the production of pigments independently, and each has different uses. This compound, also called cuprous oxide (Cu2O), is found in nature in a mineral called cuprite, although most of the compound used at the industrial level is obtained synthetically. Industrially, it can be formed by heating metallic copper at extreme temperatures or electrolysis of saline solutions with the help of copper electrodes and by mixing some other copper composites with reducing agents. CuprousOxide is a red crystalline powder, and its melting point is 1232 °C. It oxidizes slowly to copper (II) oxide in humid air. Although it is insoluble in any organic solvent and water, it reacts with strong acids, for example, nitric, sulfuric, and hydrochloric acid, to produce salts. It also reacts with strong bases, for example, potassium and sodium hydroxides, to produce compounds called cuprates.
Copper Oxide (II)
It is also called cupric oxide (CuO), which exists in nature as a black or gray mineral called tenorite. It exists in black solid form, melting temperature higher than 1200 °C. Copper (II) oxide is insoluble mainly in solvents but can react with acids to form copper salts. Like cuprous oxide, copper (II) can be manufactured by heating elemental (metallic) copper but at lower temperatures. This production method generates an impure form of the oxide; however, there are alternative ways of obtaining it, for example, by heating some oxygen-containing copper compounds such as carbonate, hydroxide, or nitrate.
Price of copper oxide
Copper oxide particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of Copper oxide. A large amount of large amount will be lower. The Price of copper oxide is on our company's official website.
