A black solid, it is one of the two stable oxides of copper, the other being Cu 2 O or copper(I) oxide (cuprous oxide). As a mineral, it is known as tenorite, or sometimes black copper. It is a product of copper mining and the precursor to many other copper-containing products and chemical compounds. [3]
Copper oxide may refer to: Copper(I) oxide (cuprous oxide, Cu 2 O) Copper(II) oxide (cupric oxide, CuO) Copper peroxide (CuO 2), a hypothetical compound; Paramelaconite (copper(I,II) oxide, Cu 4 O 3) Copper(III) oxide (Cu 2 O 3) does not exist although Cu(III) is a component of cuprate superconductors; Copper(IV) oxide (CuO 2) has been proposed ...
Copper(I) oxide or cuprous oxide is the inorganic compound with the formula Cu 2 O. It is one of the principal oxides of copper, the other being copper(II) oxide or cupric oxide (CuO).The compound can appear either yellow or red, depending on the size of the particles. [2] Cuprous oxide is found as the mineral cuprite.
A simple example is potassium cuprate, KCuO 2, a blue-black solid. [18] The most extensively studied copper(III) compounds are the cuprate superconductors. Yttrium barium copper oxide (YBa 2 Cu 3 O 7) consists of both Cu(II) and Cu(III) centres. Like oxide, fluoride is a highly basic anion [19] and is

Copper used in buildings, usually for roofing, oxidizes to form a green patina of compounds called verdigris. Copper is sometimes used in decorative art, both in its elemental metal form and in compounds as pigments. Copper compounds are used as bacteriostatic agents, fungicides, and wood preservatives.
Copper is a chemical element with the symbol Cu (from Latin: cuprum) and the atomic number of 29. It is easily recognisable, due to its distinct red-orange color.Copper also has a range of different organic and inorganic salts, having varying oxidation states ranging from (0,I) to (III).
Tenorite, sometimes also called Black Copper, is a copper oxide mineral with the chemical formula CuO. The chemical name is Copper(II) oxide or cupric oxide.
