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 one of most insoluble substances, second only to silver, mercury, and sulphide sulfur.

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 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 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 in a moderate manner. 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 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-sulfide minerals varies widely, and is a 0.5 Cu/S2 mixture that includes many nonstoichiometric substances.

How does Copper Sulfide Powder get produced?
The reaction between sulfur and copper is not a direct mix, as the sulfur oxidation rate is low. This will result in a mixture of cuprous sulfide with 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
