Coppersulfide, or Coppersulphide, is an inorganic substance. Copper Sulfide Chemical Formula is: CuS. The cuprous ion is a dark brown, extremely polar ion. It is one of most insoluble substances, second only to silver, mercury, and sulphide sulfur.

About Copper sulfide cuS powder:
Copper Sulfide is inorganic compound, with chemical formula cuS. It is black and brown powder or granular material. 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 sulfide is both a mineral and a compound. It can be classified in three different categories: mixed single sulfide , single sulfide , and disulfide . Copper sulfide, also known as cuprizone, is a naturally occurring mineral. It conducts electrical current moderately. Minerals and synthetic materials both contain copper sulfide.
Copper sulfide refers to a variety of compounds and minerals 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, a copper-iron mixed sulfide compound, are often called "copper" sulfide. The composition of copper-sulfide minerals varies widely, and is a mixture of copper-iron sulfide.

How does Copper Sulfide Powder get produced?
The reaction between copper and sulfur cannot be heated directly, as the sulfur oxidation rate is low. This will lead to a mixture consisting of copper sulfide (and cuprous sulfur):
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
