Laser melting method: The laser melting method is a method that uses a high-power laser beam to melt copper raw materials and quickly cool them to prepare nano copper powder. However, the laser melting method also has shortcomings, such as high equipment cost and low production efficiency.

Vacuum evaporation method: The vacuum evaporation method prepares nano copper powder by heating raw material to above the melting point in a vacuum environment and then rapidly cooling it. However, the vacuum evaporation method also has some things that could be improved, such as high equipment cost and low production efficiency.

Chemical law

The chemical method is another standard method for preparing nano copper powder, including the chemical reduction, electrochemical, and vapor deposition methods.

Chemical reduction method: The chemical reduction method prepares nano copper powder by reducing copper ions to copper elements by chemical reducing agent. However, the chemical reduction method has shortcomings, such as the prepared nano copper powder size distribution being comprehensive and the shape being more irregular.

Electrochemical reduction method: The electrochemical reduction method prepares nano copper powder by reducing copper ions to copper elemental by electrochemical reaction. However, the electrochemical reduction method also has shortcomings, such as high equipment cost and low production efficiency.

Vapor deposition method: It prepares nano copper powder by depositing copper on the substrate through a chemical reaction or physical process in a gas or steam environment. The nanometer copper powder prepared by this method has a small particle size and high crystallinity. However, the vapor deposition method has disadvantages, such as increased equipment cost and low production efficiency.
