Copper Selenide Properties
Features of  Copper Selenide Cu2Se Powder  :
Cuprous selenide is black cubic crystal at room temperature, with a relative density of 6.749, a melting point of 1113°C, and a molecular formula of Cu2Se. Soluble in potassium cyanide solution. Hydrogen selenide escapes when dissolved in hydrochloric acid. When interacting with sulfuric acid, sulfur dioxide gas occurs. It can be oxidized by nitric acid to copper selenite. It is obtained by heating a stoichiometric mixture of copper and selenium in a vacuum quartz sealed tube or by reducing an ammonia solution of copper salt and selenite by hydrazine hydrate. Used as a semiconductor.
