Purity: min 99%
Copper sulfide is an inorganic compound with a chemical formula of CuS or CuI2CuII(S2)S. Therefore, two-thirds of the sulphur is actually a persulfate ion, and two-thirds of the copper is a cuprous ion, which is dark brown and extremely polar. Insoluble, it is one of the most insoluble substances (second only to silver sulfide, mercury sulfide, and sulphide sulfide) because its poor solubility makes some seemingly unacceptable reactions.

About Copper Sulfide CuS Powder:
Copper sulfide is an inorganic compound with the chemical formula CuS, so it is actually a mixture of cuprous sulfide and supersulfide and is a black and brown amorphous powder or granular substance. It is extremely insoluble and is one of the most difficult substances to dissolve because its insolubility allows some seemingly impossible reactions to occur. Bonding in copper sulfide cannot be correctly described in terms of simple oxidation state forms because the properties of the Cu-S bond are somewhat covalent rather than ionic and have a high degree of delocalization, resulting in a complex electronic band structure.
Copper sulfide is a compound and mineral, which can be divided into three categories: single sulfide, disulfide and mixed single sulfide. Copper sulfide is naturally occurring in nature as a mineral, called cuprizone. It conducts electricity moderately. Both synthetic materials and minerals contain copper sulfide.
Copper sulfide describes a series of compounds and minerals from which minerals and synthetic materials are composed. Some copper sulfides are economically important ores. The main copper sulfide minerals include Cu2S(chalcocite) and CuS(copper porphyry).In the mining industry, bornite or chalcopyrite consisting of a mixed copper-iron sulfide is often referred to as "copper sulfide".In chemistry, "binary copper sulfide" is any binary compound of the elements copper and sulfur. Regardless of their origin, the composition of copper sulfides varies greatly at 0.5 Cu/S 2 and includes many non-stoichiometric compounds.

How is Copper Sulfide CuS Powder produced?
No sulfur and copper directly mixed heating to prepare copper sulfide, because the oxidation of sulfur is weak, the reaction will generate a mixture of copper sulfide and cuprous sulfide:
2Cu+S==△==Cu2S  ,   Cu+S==△==CuS
Can make copper powder and sulfur dissolved in carbon disulfide reaction at 100℃ to produce pure copper sulfide:
Cu+S==100℃ ,  CS2==CuS
Laboratory preparation of copper sulfide is usually prepared by adding H2S gas or soluble sulfide (such as sodium sulfide) into copper salt (mainly copper chloride and copper sulfate) solution through double decomposition reaction:
CuCl2+H2S====CuS↓+2HCl (weak acid to strong acid)
This reaction can occur because copper sulfide is too insoluble, causing the equilibrium to shift to the right.
Applications of Bismuth Oxide Bi2O3 powder:
Copper sulfide has the following uses:
Solar cell
Superionic conductor
Conductive electrode
Photothermal spectral analysis conversion equipment
Microwave shielding coating
An active absorber of radio waves
Gas sensor
Infrared radiation polarizer

Storage Condition of Copper Sulfide CuS Powder:
The damp reunion will affect CuS powder dispersion performance and using effects, therefore, Copper Sulfide CuS Powder should be sealed in vacuum packing and stored in a cool and dry room, the Copper Sulfide CuS Powder can not be exposure to air. In addition, the CuS powder should be avoided under stress.
