What are silicon nanoparticles?

Silicon nanoparticles refers to crystalline silicon particles less than 5 nanometers (1 billion (1G) of a meter) in diameter. Nano silicon powder has the characteristics of high purity, small particle size, and uniform distribution. With the characteristics of large surface area, high surface activity, and low loose density, the product is non-toxic and tasteless. Nano silicon powder is a new generation of photoelectric semiconductor material, which has a wide gap energy semiconductor and is also a high-power light source material.

Silicon nanoparticles production and preparation
At present, there are three main preparation methods of silicon nanoparticles powder: mechanical ball milling, chemical vapor deposition, and plasma evaporation and condensation. The industrial production of nano silicon powder in western countries started earlier, and there are specialized silicon powder products companies, such as Japan Teirenji, Dupont, Germany H.C.Stark, Canada Tekner, etc., can apply plasma evaporation and condensation method to produce a variety of high purity nano silicon powder with different particle sizes, which is in the world's leading position in terms of production technology.
In China, the development of nano-silicon powder started late and the manufacturing level is relatively backward. Usually, the mechanical ball milling method is used to synthesize nano-silicon powder. A small number of universities and research institutes can prepare nano-silicon powder by chemical vapor deposition and plasma evaporation condensation method, but it is only at the experimental level and cannot achieve mass production.
Performance characteristics
