What Does Cupric Oxide Mean?

Cupric oxide, also known as copper (II) oxide, refers to an inorganic chemical compound composed of copper and oxygen with the chemical formula CuO. Cupric oxide nanoparticles are used industrially to produce paints, and act as catalysts in organic synthesis due to its corrosion preventative properties.


Corrosionpedia Explains Cupric Oxide

Cupric oxide is used to facilitate corrosion resistance on copper substrate structures by self-proliferation on the metal's surface. This occurs through a simple immersion in an acetate buffer or sodium hydroxide solution.

Cupric oxide protection presents some harmful effects when used in copper cookware. When the copper cooking surface come into contact with acidic food, a toxic verdigris (patina) is produced, which is poisonous if ingested. Additionally, copper electrical wires and copper pipes must be cleaned with acid-free cleaners before soldering. Care must be taken when soldering to not overheat the copper, which may prevent the solder from adhering. Oxidation also hinders the electrical conductivity of copper wire.
