1. Product Introduction
Cupric Oxide/Copper Oxide (CuO) is the higher oxide of copper. As a mineral, it is known as tenorite. It is a black solid with an ionic structure which melts above 1200 °C with some loss of oxygen. It can be formed by heating copper in air. Copper(II) oxide is a amphoteric oxide, so it dissolves in mineral acids such as hydrochloric acid, sulfuric acid or nitric acid to give the corresponding copper(II) salts.
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
