A black colloidal precipitate of CuS is formed when hydrogen sulfide, H2S, is bubbled through solutions of Cu(II) salts. Both minerals and synthetic materials comprise these compounds. Copper(I) sulfide is a copper sulfide, a chemical compound of copper and sulfur. There are two forms of Cu2S: a low temperature monoclinic form ("low-chalcocite") which has a complex structure with 96 copper atoms in the unit cell [7] and a hexagonal form stable above 104 °C. These compounds can be differentiated by their crystalline structure. Cu2S reacts with oxygen to form SO2:[6], In the production of copper two thirds of the molten copper sulfide is oxidised as above, and the Cu2O reacts with unoxidised Cu2S to give Cu metal:[6]. Copper monosulfide is a chemical compound of copper and sulfur. Dicopper sulfide. The refining techniques employed by copper producers depend on the ore type, as well as other economic and environmental factors. Copper sulfides describe a family of chemical compounds and minerals with the formula CuxSy. It is one of the principal oxides of copper, the other being CuO or cupric oxide. Skin wound caused by trauma, inflammation, surgery, or burns remains a great challenge worldwide since there is no effective therapy available to improve its clinical outcomes. Therefore, the copper film is coated on the steel, aluminum and stainless steel by the special painting method, not coloring by electrical plating. While some are similar to their phosphorus analogues, the phosphorus sulfides, there are some new forms, molecular P2Se5 and the polymeric catena-[P4Se4]x. DATE OF LAST REVISION: 07/09/15. It is a white crystalline, hygroscopic solid with a rutile-type crystal structure, similar to other fluorides of chemical formulae MF2 (where M is a metal).
