What is nano-silicon powder? Silica powder, its color changes slightly with its carbon content. The whiteness of silica powder is between 40 and 50, the bulk density is about 200 kg/m3. Nano-silica powder refers to crystalline silicon particles less than 5 nanometers. It has the characteristics of high purity, small particle size, uniform distribution, large specific surface area, high surface activity, and low bulk density. It is non-toxic, tasteless, and has good activity; It is a new optoelectronic semiconductor material with wide gap energy.
Preparation of nano-silicon powder The preparation methods of nanometer silicon powder mainly include mechanical ball milling, chemical vapor deposition, and plasma evaporation condensation. The industrial production of nanometer silicon powder in western countries started earlier. Specialized silicon powder products companies, such as Japan's Teuton, DuPont, Germany's H.C.Stark, and Canada's Texana, can use the plasma evaporation condensation method to produce a variety of different sizes of Chemicalbook high-purity nanometer silicon powder. Production technology is in the leading position in the world. The research and development of nano-silicon powder in China started relatively late, and the manufacturing level is relatively backward. Generally, the nano-silicon powder is synthesized by mechanical ball milling. Some universities and scientific research institutes can prepare nano-silicon powder by chemical vapor deposition, plasma evaporation, and condensation. Still, it is only at the experimental level and can not achieve mass production.
Application of nano-silicon powder Nano-silicon powder is a new generation of photoelectric semiconductor material: silicon is a typical semiconductor material, nanocrystalline is an excellent solar material, amorphous is used as electrode material in lithium battery, nanocrystalline has strong activity, low sintering temperature, high strength and toughness, strong dielectric loss, wide band gap semiconductor, memory device, high power optical material, nano-silicon powder can be used in high-temperature resistant coating and refractory materials, and can also be used in fuel cells to replace nano-silicon powder, Reduce costs (1) Make nano-silicon wires from nano-chemicalbook silicon powder and use them in the cathode material of rechargeable lithium batteries, or coat graphite on the surface of nano-silicon powder to use as the cathode material of rechargeable lithium batteries, which increases the capacitance and charge-discharge cycle times of rechargeable lithium batteries by more than three times (2) Nano-silicon powder can be applied to coatings to form silicon nano-film, which is widely used in solar energy (3) Nano-silicon powder and diamond are mixed under high pressure to form silicon carbide-diamond composites, which are used as cutting tools.
Price of nano-silicon powder Nano-silicon powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of nano-silicon powder. A large amount of large amount will be lower. The price of nano-silicon powder can be found on our company's official website.
