High Purity Copper Sulfide CuS CAS 1317-40-4, 99%

Product Name: CuS Powder Copper Sulfide Powder CAS 1317-40-4
Purity: minimum 99%
Coppersulfide, or coppersulphide, is an inorganic substance. Copper Sulfide Chemical Formula is: CuS. The cuprous ion is dark brown in color and is very polar. It is very insoluble (second to only silver sulfide), mercury sulfide or sulphide sulfur).

About Copper sulfide cuS powder:
Copper Sulfide is inorganic compound, with chemical formula cuS. It's a black or brown amorphous granular powder. The insolubility of copper sulfide makes it one of most difficult substances in the world to dissolve. The bonding of copper sulfide can't be accurately described as simple oxidation forms, because the properties are covalent and not ionic. This results in a complex band structure.
Copper sulfideis both a mineral and a compound. It can be divided in three categories, single sulfide or mixed single sulfide. Copper sulfide, also known as cuprizone, is a naturally occurring mineral. It conducts electrical currents moderately. Minerals and synthetic materials both contain copper sulfide.
Copper sulfide refers to a variety of minerals and compounds that are used in the production of synthetic materials and minerals. Some copper sulfides have economic importance. Copper sulfide includes Cu2S (chalcocite) as well as CuS (copper porphyry). In the mining world, bornite and chalcopyrite, which are a mix of copper-iron sulfur, are often called "copper" sulfide. The composition of copper-sulfides is very variable, and can include many nonstoichiometric substances.

How does Copper sulfide cuS powder get produced?
The reaction between sulfur and copper is not able to be heated directly, and the result will be a mixture of cuprous sulfide.
2Cu+S==^==Cu2S , Cu+S==^==CuS
Copper powder and sulfur can be dissolved in carbon dioxide at 100 degrees to make pure copper-sulfide.
Cu+S==100 , CS2==CuS
Double decomposition is used to prepare copper sulfide in the laboratory.
CuCl2+H2S====CuS|+2HCl (weak acid to strong acid)
This reaction may occur when copper sulfide becomes too insoluble and causes the equilibrium balance to shift to the left.
CuSO4+Na2S====CuS|+Na2SO4
