Nano-copper powder is purple-brown or purple-black powder. The copper atoms in nano-copper powder are the same as those in ordinary copper powder, except that the copper particles of nano-copper powder are very small and the chemical properties are more active.
Nano copper powder has excellent characteristics such as large specific surface area, strong adsorption capacity and high surface activity, so that nano metal particles have high catalytic efficiency, and have important and extensive use value in chemical catalysis. In addition, nano-copper powder can be used as gel propellant, combustion activator, water cleaning adsorbent, sintering activator, etc. With the development of the electronics industry, the ultra-fine thick film paste prepared from nano-copper powder will play an important role in large-scale integrated circuits. At the same time, the price is lower than the precious metal silver powder and palladium powder, and it has broad application prospects.
In recent years, with the continuous development of my country’s nano-copper powder preparation technology, the production capacity and output of nano-copper powder have continued to increase. Relevant data show that in 2018, the production capacity of my country’s nano copper powder industry was about 35 tons, and the output was about 17.2 tons. The domestic nano copper powder industry’s capacity utilization rate was about 49.14%. With the continuous development of the chemical and electronic industries, the demand for nano copper powder continues to rise. In 2018, the demand for China’s nano copper powder industry was about 17.8 tons, a year-on-year increase of 32.83%. Among them, the demand for particle size greater than 100nm is 12.99 tons; the demand for particle size less than 100nm is 4.81 tons. With the continuous development of the nano copper powder market, the scale of the industry has also increased rapidly. The data shows that the scale of the domestic nano copper powder industry in 2018 was about 33,599,500 yuan.
At this stage, nano-copper powder is mainly used in the electronics industry, chemical industry, machinery industry and pharmaceutical industry and other fields. With the development of the economy and the deepening of research, the industry demand for nano-copper powder will increase and the application range will be more extensive. Therefore, nano-copper powder has huge market potential in the future.
