What are the properties of nanosilica powder?
Nano silicon powder
The term crystalline silicon is used to describe particles that are less than 5 nanometers in diameter (one billion (1G), of a meter). Nano silicon powder is known for its purity, small particles and uniform distribution. This product is nontoxic and tastesless because of its large surface, high surface activity as well as low bulk density. Nano silicon is a new type of optoelectronic material with wide-gap semiconductors. It is also used as a high power light source.
The method used to prepare nanosilica powder uses variable current laser beam ion phase. It has high purity, uniformity, high surface activity and high specific surface area.
What is the use of nano-silicon powder?
1. You can use nanosilicon powder to make nanosilicon wires in the negative electrode materials of rechargeable Lithium batteries, or you can use graphite as the negative electrode materials of rechargeable Lithium batteries. This will increase the capacity and number of charge-discharge cycling of rechargeable Lithium batteries by 3 times.
2. It is used as a raw material for organic silicon polymer materials and high temperature resistant coatings.
3. Nanosilicon powder is applied to coatings in order to form a thin, film-like layer of nanosilicon particles. This technology is used widely for solar energy.
4. The nano-spherical powder of silicon and the diamond are mixed together under high pressure in order to produce a nano-silicon carbide—diamond material that can be used as a cutting instrument to increase strength and durability;
5. The theoretical specific capacity of nano-silicon for lithium-ion cells is 4200mAh/g, which is higher than the carbon material.
6. On the nano-silicon surface, ten different nano-silicon structures are designed. These nano-structures can be used to produce photoluminescence for the main wavelength ranges from near UV to near Infrared as well as low threshold voltages electroluminescence.
