• Description: 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. Copper(II) oxide or cupric oxide is an inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu2O or copper(I) oxide (cuprous oxide). As a mineral, it is known as tenorite. It is a product of copper mining and the precursor to many other copper-containing products and chemical compounds.Mainly used in wood preservatives, ceramics, and mineral supplements for animal feed.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 concern due to toxic and mutagenic particles generating reactive oxygen species.
• Uses: 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. Cupric Oxide can be used as a dietary ingredient and as a nutrient. Copper aids in the absorption of iron, in the formation of red blood cells and the proper bone formation and maintenance.As pigment in glass, ceramics, enamels, porcelain glazes, artificial gems; in manufacture of rayon, other Cu Compounds; in sweetening petroleum gases; in galvanic electrodes; as flux in metallurgy; in correcting Cu deficiencies in soil; as optical-glass polishing agent; in antifouling paints, pyrotechnic compositions; as exciter in phosphor mixtures; as catalyst for organic reactions; in high tempereture superconductors. Nanoscale Copper(II) Oxide has been studied as photocatalysts, sensors, lubricant additives and batteries. Nanorods of cupric oxide have also shown advantages as oxidizing agents in high speed chemical reactions over traditional cupric oxide nanoparticles. Copper(II) oxide is a promising p-type oxide material although with a small band gap.
