About Copper Selenide Cu2Se Powder:
Cuprous selenide, molecular formula Cu2Se, is a black cubic crystal at room temperature, relative density 6.749, melting point 1113℃, molecular formula Cu2Se. But it’s non-stoichiometric. It is a semiconductor and is often grown in the form of nanoparticles or other nanostructures. Cuprous selenide is dissolved in potassium cyanide solution. Hydrogen selenide escapes when dissolved in hydrochloric acid. In reaction with sulfuric acid, sulfur dioxide gas is produced. Can be oxidized to copper selenite by nitric acid. Kmpass is a trusted global Copper Selenide Cu2Se Powder supplier. Feel free to send an inquiry about the latest price of Copper Selenide at any time.
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.
Specification of Copper Selenide Cu2Se Powder :
High purity cuprous selenide -05 purity 99.999% above, silver, aluminum, arsenic, gold, cadmium, chromium, copper, iron, magnesium, manganese, nickel, lead, tin, zinc impurity total content less than 10ppm;
Ultra-pure cuprous selenide -06 purity 99.9999% above, silver, aluminum, arsenic, gold, cadmium, chromium, copper, iron, magnesium, nickel, lead, zinc impurity total content less than 1ppm.
How is Copper Selenide Cu2Se Powder produced?
Cuprous selenide is prepared by heating a stoichiometric mixture of copper and selenium in a vacuum quartz sealed tube or by reducing a solution of copper salt and ammonia of selenite by hydrazine hydrate.
Applications of Copper Selenide Cu2Se Powder:
Cuprous selenide is used as a semiconductor. Cuprous sulfide is an in-situ production method that forms a black protective layer on steel parts during cold heading. A bluish solution acting in this way is usually labeled as containing selenic acid or selenium dioxide. It is also being studied for the treatment of colon cancer.
