Silicon nanoparticles are spherical high surface area metal particles

Overview of Silicon Nanoparticles

Silicon (Si) nanoparticles, nanodots, or nanopowders are spherical high surface area metal particles. Nano-scale silicon particles are usually 5-25 nanometers (nm), the specific surface area (SSA) is in the range of 30-70 square meters/g, and the average particle size is 80-100 nanometers, and the specific surface area is about 5 nanometers to 10 square meters. 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 bulk density, the product is non-toxic and tasteless. Nano silicon powder is a new generation of optoelectronic semiconductor materials with wide gap energy semiconductors and is also a high-power light source material.

 Silicon nanoparticles (SiNPs) are biologically compatible, metal-free quantum dots that exhibit size and surface tailorable photoluminescence. The thin film deposition of silicon nanoparticle quantum dots on the polysilicon substrate of photovoltaic (solar) cells emits fluorescence by capturing the incident light emitted before, thereby increasing the voltage output by up to 60%. Nano silicon particles also have ultra-high purity and high purity, as well as carbon coating and dispersion forms. They can also be obtained as a dispersion through the AE Nanofluid production department. Nanofluids are generally defined as nanoparticles suspended in solution using surfactants or surface charge technology.

 Nanoparticles are ultrafine particles having one dimension that measures 100 nm or less. Unlike bulk materials, these particles have greater surface area per weight. Therefore, the properties of materials change as their size approaches the nanoscale. Silicon nanoparticles have a lower bulk density and larger specific surface area than bulk crystalline silicon. When exposed to air, the dispersion performance of these nanoparticles will be affected. Therefore, the nanoparticles should be stored in a cool and dry room.

Applications of Silicon Nanoparticles 

Silicon nanoparticles have a large specific surface, colorless and transparent; low viscosity, strong penetrating ability, and good dispersion performance. The silicon dioxide particles of nano-silicon are of nanometer level, and their particle size is smaller than the length of visible light. It will not reflect or refract the visible light, so it will not make the paint surface matte.

1.It can react with organic matter and be used as a raw material for organosilicon polymer materials.

2.Silicon metal is purified to produce polysilicon.

3. Metal surface treatment.

5. Semiconductor microelectronic packaging materials.

6. In car beauty products: increase luster and fill up micro cracks on the surface.

7. Application of nano silicon in lithium battery

Due to the high absorption rate of nano-silicon to lithium batteries, the use of nano-silicon with lithium batteries can greatly increase the capacity of lithium batteries (theoretical can reach 4000mA/h). At the same time, the world's advanced technology is used to coat the surface of nano-silicon powder with graphite, Composed of Si-C composite material, can effectively reduce the expansion due to silicon-absorbing lithium ions, and at the same time can increase the affinity with the electrolyte, easy to disperse, and improve cycle performance.
