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 copper super sulfide, 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. The bonding of copper sulfide cannot be properly described in the form of a simple oxidation state because the nature of the Cu-S bond is somewhat covalent rather than ionic and has a high degree of dissociation leading to a complex electronic band structure.

Characteristics of copper sulfide

Copper sulfide is an important transition metal sulfide with good catalytic activity, visible light absorption, photovoltaic power generation, third-order nonlinear polarizability and third-order nonlinear response rate, which has good prospects for application in solar cells, photoelectric conversion switches, gas-sensitive sensors and other fields. With the development of nanotechnology, due to quantum size effect, surface effect and macroscopic quantum tunnelling effect, copper sulfide nanocrystalline materials have become one of the research hotspots at home and abroad with incomparable photoelectric properties, catalytic ability, high electrical conductivity and high-energy capacitive properties of bulk materials.

Applications of copper sulfide

As an important semiconductor material, copper sulfide is widely used in thermocouples, optical recording, light filters, solar cells, as well as dry powder coatings, fluorescent materials and superconductors. In addition, the fast ionic conductivity exhibited by copper sulfide at high temperatures is of great interest to many researchers. At present, the preparation of copper sulfide nanomaterials mainly includes chemical deposition, acoustic chemistry, hydrothermal synthesis and microwave radiation methods. These methods generally require a long reaction time, high temperatures and pressure, and special reaction devices.

According to the morphology of copper sulfide nanocrystalline materials, they can be classified into nanoparticles, nanorods, nanowires, nanotubes and nanoflowers, etc. They can be synthesized by hydrothermal, wet chemical synthesis, template and microwave methods, which provide a variety of new nanomaterials for the construction of nanodevices and promote the possible applications of copper sulfide nanocrystalline materials.

Since copper sulfide decomposes and reacts in different atmospheres, copper sulfide nanocrystals synthesized by various methods described above need to be dried in a vacuum drying oven to prevent oxidation of copper sulfide nanocrystal materials and stored at room temperature. Therefore, the copper sulfide nanocrystals synthesized by various methods are stable.

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.
