How to produce spherical copper powder?

There are two main production methods for spherical copper powders:

Chemical Vapor Deposition: This method requires the provision of metal-organic compound vapors and hydrogen as raw material gases, which are reacted at high temperatures, resulting in homogeneous and mature copper grains that are prepared by coalescence. The spherical copper powder prepared by this method has excellent fluidity and uniformity and is inexpensive enough to realize mass production. However, copper powders prepared by chemical vapor deposition often have large grains, insufficient sphericity, and the presence of impurities, which is a limiting factor for their application.

Hydrothermal synthesis: This method uses hydrothermal reaction at high pressure and temperature to generate microstructured, mature, and regular dispersed spherical particles in a solution of copper ions by a synthesis reagent. This method has the advantages of simplicity, low cost, and non-hazardousness and is capable of producing high-quality copper powders. However, the preparation of copper powders by hydrothermal synthesis requires consideration of the selection of a suitable dispersant to produce a number of hydrothermal products, leading to changes in the quality of copper powders during post-processing, and it is not easy to control the size and distribution of the particles, so it can not meet the needs of different fields of application.


What is the application of spherical copper powder? 

Spherical copper powder has a wide range of uses, and the following are some of the main application areas:

Powder metallurgy field: Spherical copper powder is one of the main raw materials for powder metallurgy, which can be used to manufacture various copper-based alloy parts and products.

Electric carbon products field: spherical copper powder can be used for the production of high conductivity and high hardness electrical carbon products, such as graphite electrodes, silicon carbide, and so on.

Electronic materials field: spherical copper powder has high electrical conductivity and high thermal conductivity, and can be used to manufacture a variety of electronic components, such as circuit boards, connectors, and electronic packaging materials.

Metal coating field: spherical copper powder can be used as a filler of metal coating to improve the conductivity and anti-corrosion properties of the coating.

Chemical catalyst field: spherical copper powder can be used as the catalyst carrier of chemical reaction to improve the efficiency of chemical reaction and product purity.

Filter field: Spherical copper powder can be used to manufacture high-efficiency filters to improve air purification and filtration effect.

Heat sink field: spherical copper powder can be used to manufacture high-efficiency heat sinks to improve the heat dissipation performance of electronic equipment.

In short, as a high-performance metal powder material, spherical copper powder has a wide range of application prospects in various fields.
