What is silicon nanoparticles
Silicon nanoparticles is crystalline silicon particles with a diameter of less than 5 nanometers. Silicon nanoparticles has the characteristics of high purity, small particle size and uniform distribution. It also has the characteristics of large surface area, high surface activity and low bulk density. The product is non-toxic and tasteless. silicon nanoparticles is a new generation of optoelectronic semiconductor material, which has a wide gap energy semiconductor and is a high-power light source material.
As a "spokesperson" for new materials in the 21st century, silicon nanoparticles materials have brought people unlimited imagination. Compared with other materials, silicon nanoparticles not only has the advantages of environmental protection, odorless, non-toxic, but also has the characteristics of small size, high temperature resistance, stable chemical properties, etc., and its excellent characteristics have generated broad application prospects.

Preparation of silicon nanoparticles
In the course of development history, silicon nanoparticles is mainly based on two preparation methods. The first is dry method, focusing on gas phase method, and the second is wet method. Wet method has more types, including precipitation method and sol-gel method. Focus. The dry method has the advantages of stable chemical properties and high purity, but considering its disadvantages such as large energy consumption, high cost, and complicated preparation process, the penetration rate is low. Therefore, the preparation of silicon nanoparticles materials uses more wet processes.
1. Gas phase method: The operation process of the gas phase method uses SiCl4 as a raw material to burn violently under the environment of oxyhydrogen gas and decompose into SiO2. silicon nanoparticles extracted by this method has the advantages of high purity and small volume. However, the gas phase method has two major disadvantages in the preparation process. One is that the preparation cost is high, and the other is that the preparation process is complicated and changeable. Therefore, the application rate of this method is extremely low.
2. Precipitation method: putting nitrate in acidified environment will decompose to produce SiO2 crystal. The use of this method is a good supplement to the gas phase method, with the advantages of low cost, low energy consumption, simple preparation process, good dispersion, etc., but the disadvantage is that the product quality is low.
3. Sol-gel method: This method puts the inorganic salt into a water-containing vessel to decompose it to cause a chemical reaction to produce a sol, then convert the sol into a gel, and finally put the polymer in a dry environment to age and obtain high Purity of SiO2.

Development prospects of silicon nanoparticles
As the focus of scientific research in the new century, silicon nanoparticles materials are mainly composed of silica, which not only has excellent properties such as non-toxic, harmless, and odorless, but also exhibits in the fields of physics, chemistry, biology, industrial manufacturing, etc. Out of its own unique advantages. At present, silicon nanoparticles materials are gradually being discovered by the broad market. Broad application prospects and huge market value are being applied and developed in industries such as printed circuit boards, substrates, and plastics.
