About Copper Powder Cu Powder:
Since the application of metal copper is very wide, the consumption and production capacity in the metallurgy of toned metallurgy is second, second only to aluminum. The nano-copper powder is well thermally conductive, self-lubricity, and high activity, making it an important role in many areas, such as electrical, mechanics, chemistry, etc. This is derived from the unique basic characteristics of nano-copper powder: surface interfaces effect, quantum dimensional effect and quantum tunnel effect. Macroscopic, copper powder has a high activity, so oxidation occurs in air, soluble in thermal sulfuric acid and nitric acid. At present, the nano-copper powder is often used as catalysts, lubricants, conductive coatings, and is also widely used in engineering structural materials, aerospace and biological engineering.
 
Copper is a very durable and ductile metal that is widely used due to its thermal conductivity and conductivity. Copper can be used in wires or combined with other metals to form different alloys (such as copper, copper and copper). Bronze is formed in conjunction with tin. When exposed to air, the outer copper layer is slowly oxidized into black copper oxide. According to different conditions, it can also form copper carbonate, a green copper roof or copper coating. Feel free to send an inquiry to get the latest price if you would like to buy Copper Powder Cu Powder in bulk.

How is Copper Powder Cu Powder produced?
At present, there are many methods for preparing nano-copper powder, which can be divided into physical law and chemical methods.
Preparation of copper powder in physics method has the following methods:
1.Atomization method
The atomization method is mainly to break the metal copper liquid by high-speed airflow, thereby forming a fine droplet and then solidifying into a powder, which has become the main development trend of the current production of copper powder. The atomization method has the advantages of low production cost and small environmental pollution.
2. Mechanical ball mill
The mechanical ball milling method is widely used to prepare copper powder. The mechanism of action of the ball mill is mainly impacts collisions and rolling through metal balls, making it strong shaping deformation and constantly refining. The advantage of this method is that the process is simple, high yield, but is prone to impurities during the production process, and the powder size is not uniform.
3. Gas evaporation method
The mechanism of action of gas evaporation method is mainly to vaporize the metal copper or form a plasma in a lively atmosphere or an inert atmosphere, and then react with the lively atmosphere and cool the condensation, or by collision with the inert atmosphere, cool and condense, thereby forming a fine Copper powder. The copper powder prepared by this method has the advantages of controllable particle size, uniform shape, high purity, good crystallinity.
Preparation of copper powder by the chemical method:
1.Electrodeposition method
The electrodeposition method is to make the copper ions in the cathode in an electrochemical mode to obtain a copper powder. This method is in an important role in the preparation of the metal powder. At present, the electrodeposition method of the metal powder has a DC method, pulse method, and composite total deposition method. Electrolysis is a method of achieving scale production. It is easy to optimize the morphology, particle size, and current efficiency of electrolytic copper powder by changing the electrolysis parameters.
2. Liquid phase reduction method
The liquid phase reduction method is currently the most widely used method for preparing metal nanomaterials. The principle is to reduce the metal cation in the solution under the action of the reducing agent to prepare microns or even nanoscale metal powder by controlling various process parameters. body.
3. Vapor deposition method
The vapor deposition method is a method for reacting one or more gases to precipitate the preparation of ultrafine powder by plasma, laser, or the like. A variety of powders such as metals, alloys, oxides, sulfides, and the like can be prepared by vapor deposition.
4. Sol-gel method
The sol-gel method is mainly by hydrolyzing the metal ionic organic compound or an inorganic compound to form a sol, and then dried, grind, and calcined after solidification, thereby producing a nanofin.
