The Characteristics and Application of Copper Oxide CuO Powder

What is cuprous oxide CuO powder
Copper oxide is an inorganic substance with the chemical formula CuO. It is a black oxide of copper, slightly amphiphilic, slightly hygroscopic.
Copper oxide Virtually insoluble in water or alcohols; copper oxide dissolves slowly in ammonia solution but quickly in ammonium carbonate solution; it is dissolved by alkali metal cyanides and by strong acid solutions; hot formic acid and boiling acetic acid solutions readily dissolve the oxide.
Copper oxide is mainly used to make rayon, ceramics, glaze and enamel, batteries, petroleum desulfurizes, pesticides, and also for hydrogen production, catalysts, and green glass.
Cuprous oxide CuO is produced on a large scale by pyrometallurgy, which is a stage of extracting copper from ore. The ore is treated with an aqueous mixture of ammonium carbonate, ammonia and oxygen to obtain copper (I) and copper (II) amino complexes, which are extracted from the solid. These complexes are decomposed with steam to produce CuO.
Cupric oxide is used as a precursor in many copper-containing products such as wood preservatives and ceramics. The mean daily dietary intake of copper in adults ranges between 0.9 and 2.2 mg. Common routes of cupric oxide exposure include ingestion, dermal exposure and inhalation. Copper(II) oxide nanoparticles ( NPCuO) have industrial applications as antimicrobial agents in textiles and paints and catalysts in organic synthesis. They may also be produced from electronic wastes. Cupric oxide poses potential health and environmental concerns due to toxic and muta particles generating reactive oxygen species.

Performance of Copper Oxide CuO Powder
Copper oxide is insoluble in water and ethanol, soluble in acid, ammonium chloride and potassium cyanide solutions. It slowly dissolves in ammonia solution and can react with strong bases. Copper oxide is mainly used for making rayon, ceramics, glaze and enamel, batteries, petroleum desulfurizes, insecticides, hydrogen production, catalysts, green glass, etc.
Applications of Cuprous Oxide CuO powder
As a significant product of copper mining, copper(II) oxide is the starting point for the production of other copper salts. For example, many wood preservatives are produced from copper oxide.
Cupric oxide is used as a pigment in ceramics to produce blue, red, and green, and sometimes gray, pink, or black glazes.It is also incorrectly used as a dietary supplement in animal feed. Due to low bioactivity, negligible copper is absorbed.It is also used when welding with copper alloys.A copper oxide electrode formed part of the early battery type known as the Edison–Lalande cell. The copper oxide was also used in a lithium battery type.Besides, copper(II) oxide can be used as catalysis, superconductivity, ceramics; and catalyst carriers, electrode activity materials;glass, porcelain colorants, optical glass polishing agent, oil of desulfurized; the propellant rocket fuel speed catalyst.
