Chemische Eigenschaften
Black powder or lumps.Soluble in nitric acid and
ammonium hydroxide; insoluble in water. Occurs as
the mineral chalcocite.
Verwenden
Copper(I) sulfide is used in luminous paints, electrodes and in solar cells. It is also used for grain mounts, XRD and in microprobe standards for the identification of unknown minerals. It acts as a precursor for the preparation of copper(I) oxide and copper metal. Further, it acts as a catalyst.
Definition
ChEBI: A copper sulfide in which the metal is in the +1 oxidation state.
Allgemeine Beschreibung
Copper sulfide shows metal-like electrical conductivity, chemical-sensing capability and suitable characteristics for absorption of solar energy. Cu63 NMR, X ray photoelectron spectroscopy,2 copper sulfide CuS was studied in detail. Copper sulfide is a monovalent and oxidation state was determined to be 2.2
