Overview

Copper selenide

Molecular formula: Cu2Se

Technical connection: purification of copper and selenium (the processes used include: anode slime enrichment, electrolysis, Vacuum distillation, hydrogenation deoxidation, Zone melting...) - vacuum melting to synthesize binary alloy.

Inspection: ICP-MS; XRD; Laser particle size analyzer.

Service: Provide practical protective measures and material application solutions.

(Especially for the preparation of copper indium gallium selenium CIGS thin films by sputtering and printing processes)

Can provide technical docking

Property: Black cubic crystal. Relative density 6.749. Melting point 1113 ℃.. It is obtained by heating a stoichiometric mixture of copper and selenium in a vacuum quartz sealed tube or by reducing the ammonia solution of copper salt and Selenous acid with hydrazine hydrate. Used as a semiconductor.
