Coppersulfide, or coppersulfide, is an inorganic substance. Copper Sulfide Chemical Formula is: CuS. The cuprous ion is a dark brown, extremely polar ion. Insoluble. This is the second most insoluble substance (after silver sulfide). Its poor solubility causes some reactions that seem unacceptable.

About Copper sulfide cuS powder:
Copper Sulfide is inorganic compound, with chemical formula cuS. It's a mixture of supersulfide & cuprous sulfide. The substance is black or brown amorphous granular powder. The insoluble nature of this substance makes it one of most difficult 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 and natural materials. 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 Poudre get produced?
The reaction between copper and sulfur cannot be heated directly, as the oxidation rate of sulfur is low. This will result in a mixture of cuprous sulfide (copper sulfide) and copper 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

Application of Bismuth Oxide (Bi2O3) powder
