Copper Oxide Black /Cupric Oxide Black

An amorphous brownish-black powder, the black copper oxide may be found in the mineral’s tenorite and paramelaconite in nature. It's a pigment used in glass, artificial jewels, enamels, and ceramics. Black copper oxide is also used in copper metallurgy as an abrasive for polishing optical glass and as a flux.

Molecular Formulae- CuO

Alternative Names- Copper (II) Oxide, Cupric Oxide

Country of Origin- India

BENEFITS AND APPLICATION-

• The Edison–Lalande cell, an early type of battery, included a copper oxide black electrode. 
• The copper oxide black was also employed in lithium batteries.
• Copper oxide black, a substantial byproduct of copper mining, serves as the starting point for the manufacture of various copper salts. Many wood preservatives, for example, are made from copper oxide.
• It is a pigment used in ceramics to create blue, red, and green glazes, as well as gray, pink, and black glazes.
• Copper oxide black is erroneously used in animal feed as a nutritional supplement. Copper is absorbed insignificantly due to its poor bioactivity.
• It is used in the welding of copper alloys.
