What is nanosilica powder?

Nano silicon powder The term ‘nano silicon powder’ refers to particles of crystalline silica with a diameter less than 5 nanometers. (One billion (1G)th of a meter). The characteristics of nanosilicon powder are high purity and uniformity. 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 energy and high-power light source.
The method used to prepare nanosilica powder uses variable current laser beam ion phase. It has a high level of purity, good performance in dispersion, small particles, uniform distribution, a large surface area with high surface activity and low bulk density.

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 create a thin film with nano silicon particles. This technology is used widely for solar energy.

4. The nano-silicon carbide-diamond composite is formed by mixing silicon powder with diamond under high pressure. It can be used as a tool for strength and toughness.

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-silicon 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.
