Characteristic


Copper selenide is an inorganic binary compound consisting of copper and selenium. Its formula is sometimes described as CuSe or Cu2Se, but it is non-stoichiometric. It is a semiconductor and is frequently grown as nanoparticles or other nanostructures.


Chemical formula:Cu2Se

Molar mass:206.063 g·mol−1

Appearance:Dark blue, black

Density:6.84 g/mL



Application


Copper selenide is produced in-situ to form a protective black coating on iron or steel parts in some cold-bluing processes. Bluing solutions that operate in this manner will typically be labeled as containing selenous acid or selenium dioxide. It has also been investigated for use in the treatment of colon cancer.
