Copper Oxide CAS 1317-38-0 Black Copper Oxide Used in Fireworks Plating
1. Product Introduction
Copper oxide is black or brown-black powder, slightly hygroscopic. Density 6.3-6.9g/cm3, melting point 1326ºC, insoluble in water and alcohol, soluble in acid, ammonium chloride, potassium cyanide solution and ammonia solution. It is widely used as a pigment in ceramics to produce blue, green, and red glazes and glass. Cupric oxide is also employed as a catalyst in various chemical reactions and as a raw material in the production of other copper compounds.
copper oxide features
Color: Copper oxide compounds display distinct colors. Copper(I) oxide (Cu2O) appears as a red or brownish powder, while copper(II) oxide (CuO) is black. These colors make copper oxide suitable for use as pigments in ceramics, glass, and paints.
Electrical Conductivity: Copper oxide is a semiconductor material, meaning it can conduct electricity to a certain extent. The electrical conductivity of copper oxide can be modulated by adjusting its composition, crystal structure, and doping. This property is crucial in electronic applications, such as sensors, diodes, and solar cells.
Optical Properties: Copper oxide exhibits interesting optical properties, including absorption and reflection of specific wavelengths of light. These properties are exploited in applications such as pigments, solar cells, and optical devices.
