Copper Sulfide CuS Powder CAS 1317-40-4

Product Name: CuS Powder Copper Sulfide Powder CAS 1317-40-4
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. Feel free to send an inquiry to get the latest price if you would like to buy Copper Sulfide CuS Powder in bulk.

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.
CuSO4+Na2S====CuS↓+Na2SO4

Applications of Bismuth Oxide Bi2O3 powder:
Copper sulfide has the following uses:
Solar cell
Superionic conductor
photodetector
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.

What is Zinc Sulfide Used in?

Zinc Sulfide is an extremely versatile chemical compound. It’s used in optical materials that transmit infrared light at 12 micrometers. It is also possible to shape the material into a lens, or an optical window. You can buy it in microcrystalline sheets, which are FLIR-grade. Although it’s opaque in nature and is milky-yellow, hot isostatic pressing can make the substance clearer and more water-soluble. It’s also used to make cathode radiation tubes.

Zinc sulfuride is a white pigment. It has a tetrahedral coordination geometric and can exist in two crystal forms, sphalerite (or wurtzite). This pigment can also be synthesized and used to create windows in infrared and visible optics.

Zinc can easily be transported in the form of a dissolved metallic compound and as airborne particles. The environment is exposed to zinc because of human activity. Zinc sulfide can attach to dust particles or soil particles when it is present in the air. These tiny particles end up in ground water, where they combine with organic material. The zinc particles will eventually move into ground water and combine with organic matter. It’s unlikely that they will become toxic to plants.

Apart from being a semiconductor zinc sulfide also exhibits phosphorescence capabilities. It is particularly suited to testing the physical-mathematical model of energy bands, which explains the temporal pattern of phosphorescence. Social media is a great way to share your information.

Zinc sulfuride is used extensively in chemical industries. You can use it in plastic coatings and lubricants. It’s highly thermostable and good at dispersing and wetting. This makes it ideal for optimizing the production of high performance plastics. American Elements offers a superior quality zinc sulfide.

It is non-toxic when it comes to disposal. If you adhere to the basic guidelines, this chemical can be safely disposed. Zinc sulfuride can be neutralized using hydrogen peroxide. However, it should not go to waste with acids.

Most commonly, zinc sulfide can be used as a catalyst for batteries. Similar melting and boiling points are found in zinc sulfide. The metal is able to leach cadmium, iron, and thallium at higher temperatures. The result is white.

Food additives should be used with care. Excessive zinc intake can hinder the body’s ability to absorb other minerals and cause damage. Zinc salts can cause problems for those who deliberately consume high amounts of zinc, such as patients on zinc-salt medications. The high zinc levels in insulin injectables can be attributed to the use of these medications.

ZnS, the chemical compound zinc sulfuride (Chemical Compound Zinc Sulfide), has a large bandgap. It is an excellent semiconductor. Both its two forms, zinc mixe and wurtzite are stable at temperatures between 3 and 10 hundred degrees Celsius. ZnS has been used for semiconductor purposes as well as antimicrobial properties.

Technology Co. Ltd. has over 12 years of experience as a ZnS supplier and manufacturer. All of our products are available for shipment worldwide.
