High Purity Copper Selenide Cu2Se Powder CAS 12056-07-4 99.99% |

Cuprous selenide, which is a black cubic crystal, has a relative density (6.749) of 6.749 at room temperature. Its melting point is 1113degC and its molecular composition Cu2Se. Solvable in potassium cyanide. Hydrogen selenide can escape when hydrochloric is dissolved. In the presence of sulfuric acids, sulfur dioxide gas is formed. It can be converted to copper selenit by nitric acids. You can make it by heating copper and selenium together in a sealed vacuum quartz tube or by reducing ammonia with copper salt and selenite. Use as a semi-conductor.

What is the production process of Copper selenide Cu2Se (Powder) ?
Cuprous selenide may be produced by heating copper and selenium stoichiometrically in a quartz vacuum tube sealed with a vacuum or by reducing copper salts and ammonias of selenite using hydrazine.

Uses of Copper Selenide (Cu2Se) Powder:
Cuprous selenide, a semiconductor is also used. Cuprous sulfide, a method of in-situ manufacturing that forms a dark protective layer over steel parts when cold heading is used. The bluish solutions that act in this manner are usually labeled with selenic oxide or selenic acetate. This treatment is being tested for colon cancer.
