| COPPER(II) SULFIDE Usage And Synthesis |
| Chemical Properties | Copper(II) sulfide, CuS, [1317-40-4], MW 95.6, occurs in nature as the blue-black mineral covellite, [19138-68-2]. It is insoluble in water but is decomposed by nitric acid. In moist air, it is oxidized to copper(II) sulfate. The rate of oxidation is accelerated in the presence of alkali. Copper(II) sulfide is used as an antifouling pigment and in the preparation of aniline black dyes. |
| Uses | In antifouling paints; in preparation of mixed catalysts; in development of aniline black dye in textile printing. |
| Uses | Copper(II) sulfide is used in antifouling paints, mixed catalysts and to develop aniline black dyes in textile printing. Further, it is used as a varnish pigment and an oxidizing agent. In addition, it is used as a component of solid state electrodes and thin-film solar cell with cadmium sulfide. It is a moderate conductor of electricity and used in photovoltaics. |
| Preparation | Copper(II) sulfide is prepared by heating copper(I) sulfide in the presence of excess sulfur in a hydrogen atmosphere. Ethanol solutions of anhydrous copper(II) chloride precipitate the copper(II) sulfide on the addition of hydrogen sulfide. |
| Definition | ChEBI: Copper(II) sulfide is a copper sulfide in which the metal is in the +2 oxidation state. |
| General Description | Cu63 NMR, X ray photoelectron spectroscopy,2 copper sulfide CuS was studied in detail. |
| Hazard | Toxic by ingestion. |
