Purity: 99.99%

Product Name: CuS Powder Copper Sulfide Powder CAS 1317-40-4
Purity: minimum 99%
Coppersulfide, or Coppersulfide, is an inorganic substance. Copper Sulfide Chemical Formula is: CuS. The cuprous ion is dark brown in color and is very polar. 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 sulfide is both a mineral and a compound. It can be categorized into three different categories: mixed single sulfide , single sulfide , and disulfide . 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 compounds and minerals that are used in the production of synthetic materials and minerals. Some copper sulfides have economic importance. Copper sulfides include Cu2S (chalcocite) as well as CuS (copper porphyry). In the mining world, bornite and chalcopyrite, which are a mix of copper and iron sulfide compounds, 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 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 Powder Bismuth Oxide (Bi2O3)
Copper sulfide is used for the following purposes:
Solar cell
Superionic conductor
Photodetector
Conductive electrode
Photothermal spectrum analysis conversion equipment
Microwave shielding Coating
Radiowave absorbers that actively absorb radio waves
Gas sensor
Infrared Radiation Polarizer
