Nanosilicon powder refers to silicon particles of nanometer size. Silicon nanopowder is a new generation of optoelectronic semiconductor materials, with a wide gap energy semiconductor, but also high power light source materials.
Nano Silicon Powder Characteristics
Nano silicon powder has the characteristics of high purity, small particle size and uniform distribution. Nano silicon powder has the characteristics of large surface area, high surface activity and low loose packing density, the product is non-toxic and odourless. Nanosiliconpowders are prepared by vapour phase evaporation and condensation, with complete sphericity, high purity, small particle size, uniform distribution, large surface area, low bulk density, less cracking, easy dispersion, large volume production and high surface activity.
Nano Silicon Powder Preparation Methods
There are three main methods of preparing silicon nanopowder: mechanical ball milling, chemical vapour deposition and plasma evaporation and condensation. These companies are able to produce a wide range of high-purity silicon nanopowders with different particle sizes by the plasma evaporation condensation method, and are in a leading position in the world in terms of production technology. A few universities and research institutes can prepare nano-silica powders by chemical vapour deposition and plasma evaporation condensation, but they are only at the experimental level and cannot reach batch production yet.
Nano Silicon Powder Applications
Nanosilicon powder is a new generation of optoelectronic semiconductor materials: silicon is a typical semiconductor material, nanocrystals are excellent solar materials, amorphous in lithium batteries as electrode materials, nanocrystals are active, low sintering temperature, increased toughness, strong dielectric loss, wide energy gap semiconductor, memory devices, high power optical materials. Nanosilicon powder can be used in high temperature resistant coatings and refractory materials, and can also be used in fuel cells to replace nano carbon powder and reduce costs. Nanosilicon powder can be used in the anode material of rechargeable lithium batteries by making nanosilica wire, or the surface of nanosilicon powder can be covered with graphite to be used as the anode material of rechargeable lithium batteries, which can increase the capacity and the number of charge/discharge cycles of rechargeable lithium batteries by more than 3 times. Silicon nanopowders can be used in coatings to form silicon nanofilms, which are used in a large number of solar energy applications. Silicon nanopowder is mixed with diamond under high pressure to form silicon carbide - diamond composite materials, which are used as cutting tools. Nano silicon powder can make the curing material's tensile and compressive strength enhanced, wear resistance improved, and can increase the thermal conductivity of the curing material, increase the flame retardant performance; silicon micro powder treated by silane coupling agent has good wettability to all kinds of resin, good adsorption performance, easy to mix, no agglomeration phenomenon. The nanosilicon powder is made into nanosilicon wire used in the negative electrode material of rechargeable lithium batteries, or the surface of the nanosilicon powder is covered with graphite used as the negative electrode material of rechargeable lithium batteries, which improves the electric capacity and the number of charge/discharge cycles of rechargeable lithium batteries by more than 3 times.
