Conductive silver powder has a wide range of applications and the industry’s localization process continues to accelerate.

Conductive silver powder, also known as metal conductive powder, is the core raw material of medium and high temperature conductor slurries and electrode slurries. Conductive silver powder has the advantages of good conductivity, good antioxidant performance, and large capacitance. It is widely used in LED epoxy conductive adhesive, conductive plastics, electromagnetic shielding coatings, conductive inks, conductive ceramics and other fields. According to different production processes and uses, conductive silver powder can be divided into nano silver powder, flake silver powder, highly conductive reduced silver powder, bright silver powder, highly dispersed silver powder, highly sintering active silver powder, etc.

Wet reduction method is the mainstream preparation process of conductive silver powder. The wet reduction method refers to adding an alkaline reagent or complexing agent to an aqueous solution containing silver salt, and then adding a reducing agent to precipitate silver powder through a reduction reaction. The silver powder produced by this method has a uniform particle structure, high purity, and good conductivity. and other advantages.

The main raw material of conductive silver powder is silver salt or silver ingot. my country is a major silver producer. As the severe situation of the COVID-19 epidemic is gradually brought under control, production companies have resumed work and production, driving silver production to continue to increase. According to statistics from the Gold and Silver Branch of the China Nonferrous Metals Industry Association, in the first half of 2022, my country’s silver output reached 12,659.8 tons, a year-on-year increase of 17.0%. Gansu, Zhejiang, Hunan, Henan, Yunnan and other places are the main silver producing areas in my country. Benefiting from continuous breakthroughs in production technology and sufficient supply of raw materials, the output and quality of conductive silver powder in my country have been greatly improved.

According to the “China Conductive Silver Powder Industry Market In-depth Research and Development Prospects Forecast Report 2023-2028 released by the Industrial Research Center, conductive Silver powder has a wide range of applications, including LED epoxy conductive adhesive, conductive plastics, electromagnetic shielding coatings, conductive inks, conductive ceramics, etc. Conductive silver paste is its end product. In recent years, benefiting from the increasingly strong market demand, my country’s conductive silver paste production has continued to grow, reaching 4531.2 tons in 2021, a year-on-year increase of 7.1%. However, at present, my country’s conductive silver powder production is still unable to meet the production demand for conductive silver paste, resulting in increased dependence on product imports.

Major players in the global conductive silver powder market include Japan’s Dowa Holdings Group, AMES, and others. my country’s conductive silver powder has long been dependent on imports, but in recent years, thanks to the continuous breakthroughs in production technology of local companies, my country’s conductive silver powder production has continued to increase. Beijing Huakesheng Fine Chemical Products Trading Co., Ltd., Beijing Xingrongyuan Technology Co., Ltd., and Wuhan Zhongchen Conductive Materials Co., Ltd. are the main suppliers of conductive silver powder in my country.

Industry analysts said that conductive silver powder has a wide range of applications and strong market demand, and conductive silver paste is its end product. For a long time, due to technical barriers, my country’s conductive silver powder has been highly dependent on imports. However, with the strengthening of independent research and development capabilities of local enterprises and the sufficient supply of raw materials, the production and quality of my country’s conductive silver powder have been greatly improved, which will accelerate the localization process of the industry.
