- Introduction: Copper (II) oxide is used for blue-green pigmentation in ceramics. As a naturally occurring compound produced from mining, it is also used as a precursor to other cooper applications, including fungicide and wood preservatives. In this capacity, it is used as an antifouling paint agent for boat hulls, and other outdoor, freshwater, and seawater wood constructions. It is also occasionally used for animal feed, but incorrectly, as its copper bioavailability is inferior to of a number of other compounds including cupric acetate and alkaline Cu carbonate. Other uses include preparation of superconductors, manufacture of batteries, and as a catalyst for various industrial processes.

3. Use and Manufacturing
- 3.1 Definition
- Ablack solid prepared by the action of heaton copper(II) nitrate, hydroxide, or carbonate.It is a basic oxide and reacts withdilute acids to form solutions of copper(II)salts. Copper(II) oxide can be reduced tocopper by heating in a stream of hydrogenor carbon monoxide. It can also be reducedby mixing with carbon and heating themixture. Copper(II) oxide is stable up to itsmelting point, after which it decomposes togive oxygen, copper(I) oxide, and eventuallycopper.
- 3.2 Usage
- Copper(II) oxide is used as pigments for coloring glass, ceramics, porcelain and artificial gems; in batteries and electrodes; in antifouling paints; in electroplating; in welding fluxes for bronze; in the production of rayons; for removal of sulfur from oils; in phosphor mixtures; for polishing optical glass; and as a catalyst. It also is used to prepare various copper compounds.Copper(II) oxide is found in nature as the minerals tenorite and paramelaconite. They differ in crystalline structure: tenorite exists as triclinic crystals while paramelaconite consists of tetrahedral cubic crystals.

- 8.21 Absorption
- Following oral administration, copper is mainly absorbed through the gastrointestinal tract from the stomach, duodenum, and jejunum. All other intakes of copper (inhalation and dermal) are insignificant in comparison to the oral route. The bioavailability of copper from cupric oxide depends on the solubilization of the oxide in the gastrointestinal tract. According to studies on cattle and swine, copper oxide displays low absorption rate and high excretion rate. In rats exposed to aerosols containing 50-80 mg/m^3, pulmonary uptake of copper oxide occurred.|Copper undergoes biliary excretion.|Following exposure to cupric oxide aerosols containing 50-80 mg/m^3 in rats, particles were found in plasma 6 hours post-exposure and copper oxide was also observed in the proximal convoluted tubules of the kidney.|No pharmacokinetic data available.
- 8.22 Metabolism
