General description

Copper(II)oxide or cupric oxide (CuO) is a chemically stable black solid. As a mineral, it is called tenorite and is a critical product of copper mining. Our CuO with a trace metals purity of 99.99% is a high purity material ideal for applications in electronics, ceramics, and catalysis. CuO is a medium bandgap semiconductor with a bandgap in the range of 1.2-2.6 eV depending on the preparation conditions and usually shows p-type conductivity due to the presence of copper vacancy defects. In ceramic sciences, CuO is a key componentof many types of high Tc superconducting materials like BaYCu3O9-δ and Bi2Sr2CuO6+δ; the CuO is usually milled or mixed with other metal oxides and sintered at high temperatures to obtain complex metal oxides. In the field of catalysis, CuO is also widely used as a precursor to synthesize electrocatalysts for organic synthesis and degradation of organic pollutants.
