Copper Oxide

Cupric Oxide

Name: Copper oxide
Synonyms:Copper (I) oxide; copper(II) oxide
Formula: CuO; Cu2O
CAS No.: 1317-38-0; 1344-70-3
MW.: 79.5454; 143.09
Properties: Copper oxide is formed when copper is exposed to oxygen and oxidizes. There are two types of copper oxide: copper (I) oxide(cuprous oxide, Cu2O) and copper(II) oxide(cupric oxide, CuO).  Even though they have the came components, they each have slightly different characteristics.
Cupric oxide (CuO) is a black material that melts above 2192°F (1200℃). This copper oxide is used as a pigment in clay glazes. Cupric oxide is also used to produce cuprammonium hydroxide, a material that is used to make rayon. Some also give this form of copper oxide to animals as a copper supplement.
Cuprous oxide has the chemical formula Cu2O. Cuprous oxide is red in color and does not dissolve in water or any organic solvents. Cuprous oxide can  be used as a pigment, as a fungicide, and as an anti-fouling agent for marine paint. It is also used as a catalyst.

Application: Cupric oxide can be used as a pigment, as a fungicide, and as an anti-fouling agent for marine paint. Cupric oxide is also used as a catalyst. However, exposure to this type of copper oxide can be dangerous. Cuprous Oxide is used for ship bottom anti-fouling paint, bactericides, ceramic colorant, glass staining agent, and analytical reagent etc.

Last:Copper chloride

Next:Copper sulfate anhydrous
