High Purity Copper Powder Cu Powder CAS 7440-50-8, 99%

Description of Copper powder :

Copper powder is reddish brown, has a metallic lustre, and its particle size is usually between a few microns and tens of microns. Copper powder can be in various shapes, including spherical, needle, irregular shape, etc. Pure copper powder has good electrical and thermal conductivity; its melting point is 1083℃, and its boiling point is 2567℃. Copper powder is relatively stable to oxygen in the air at room temperature. Still, when exposed to high temperatures or humid environments, copper powder will react with oxygen to produce black copper oxide. In addition, copper powder can also react with acid to produce copper salt and chloride, bromide, etc., to produce the corresponding copper halide.

Application of Copper powder :

Copper powder is a metal powder with unique physical and chemical properties. Due to its excellent insulation properties, electrical conductivity, and corrosion resistance, it is widely used in various fields. The following are the main application areas of copper powder: 

Electrical Industry: 

Copper powder is the most widely used in the electrical industry, mainly used to manufacture wires, cables and capacitors. Due to the good conductivity of copper powder, it can effectively transmit electrical energy and ensure the stable operation of power equipment. In addition, copper powder can also be used to manufacture resistors, circuit boards, and various electronic components. 

Construction industry: 

In the construction industry, copper powder can manufacture various copper alloy doors and Windows, railings, architectural ornaments, etc., with beautiful, durable and fireproof characteristics. In addition, the copper powder can also be used to make a variety of models, moulds, artwork and so on. 

Machinery Manufacturing Industry: 

Copper powder can manufacture various mechanical parts, such as bearings, gears, pistons, etc. Because copper has good wear and corrosion resistance, it can effectively improve mechanical equipment's stability and service life. 

Automotive manufacturing: 

Copper powder also has a wide range of applications in the automotive industry. It can manufacture various parts and engine components and produce brake pads, pistons and other key parts. 

Chemical Industry: 

Copper powder is a common ingredient in producing various chemical equipment, such as reactors, valves, pipelines and so on. Due to copper's corrosion resistance and stability, it can perform well in various chemical reactions. In addition, copper powder can produce various chemical products, such as copper sulfate, copper chloride, etc. 

High-tech field: 

With the continuous development of science and technology, copper powder is increasingly widely used in high-tech fields. For example, copper powder can be used to make solar panels as a highly efficient light-absorbing material, absorbing more solar energy and converting it into electricity. In addition, copper powder can also be used in microelectronics, such as chips and integrated circuits, as conductive and thermal conductive materials.

Production Method of Copper powder :

The electrolysis method is based on copper salt solution as raw material, and copper powder is deposited on the cathode through the electrolysis process. The copper powder produced by this method has high purity fine particle size, but the production cost is high. The specific process is as follows: 

Preparation of copper salt solution: The copper raw material is dissolved in the appropriate solvent to prepare copper salt solution. 

Electrolytic process: The copper salt solution is put into the electrolytic cell, and electricity is used for the electrolytic reaction. On the cathode, copper ions gain electrons, which are reduced to copper atoms and deposited on the cathode surface. 

Separation and washing: The copper powder is separated from the electrolyte by centrifugal separation or filtration methods and then washed with water and solvents to remove surface impurities and solvents. 

Drying and screening: The copper powder is dried for subsequent processing and use. At the same time, the copper powder is screened, and the product particle size is adjusted. 

The second mechanical crushing method 

The mechanical pulverization method obtains copper powder through repeated grinding and grinding of copper plate or particle. This method has lower production costs, but the product purity and particle size are not as good as the electrolysis method. The specific process is as follows: 

Crushing and coarse crushing: The copper raw material is broken and coarsely crushed into small pieces or coarse particles. 

Grinding and crushing: The crushed copper raw material is put into the grinder or crusher for grinding and crushing. 

Separation and washing: The copper powder is separated and washed to remove impurities and pollutants. 

Drying and screening: The copper powder is dried for subsequent processing and use. At the same time, the copper powder is screened, and the product particle size is adjusted.
