n. an oxide of copper
Wikipedia
Copper oxide is a compound from the two elements copper and oxygen.
Copper oxide may refer to:
- Copper(I) oxide (cuprous oxide, CuO)
- Copper(II) oxide (cupric oxide, CuO)
- Copper peroxide (CuO)
- Copper(III) oxide (CuO)
Copper(I) oxide or cuprous oxide is the inorganic compound with the formula CuO. It is one of the principal oxides of copper. This red-coloured solid is a component of some antifouling paints. The compound can appear either yellow or red, depending on the size of the particles. Copper(I) oxide is found as the reddish mineral cuprite.
Copper(II) oxide or cupric oxide is the inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being CuO. As a mineral, it is known as tenorite and paramelaconite. It is a product of copper mining and the precursor to many other copper-containing products and chemical compounds.
Copper(III) oxide is a hypothetical inorganic compound with the formula CuO. It has not been isolated as a pure solid. Copper(III) oxides are constituents of cuprate superconductors. Copper(III) is typically stabilized in anionic environment, e.g. potassium hexafluorocuprate(III).
