The main features of nano-silver Si Powder A variable current laser beam gas phase technique is used to prepare nano-silicon powder. The product possesses high purity, a good dispersion ability, a small particle size, uniformity, a large surface area, heightened surface activity, lowered bulk density, good activities and scalable production. Nano silicon powders are able to be combined with carbon nanotubes or graphite. For lithium-ion cells, a nanosilicon-carbon anode can be formed. It increases the capacity of the batteries as well as the cycle times. This is a new generation optoelectronic material with a wide gap energy.

Nano silicon Si Powder Application
1. Use graphite to cover the surface of the nano spherical powder in order to produce silicon carbon materials for lithium rechargeable batteries. This will improve the rechargeable batteries’ electric capacity by 3 times and their number of charging and discharging cycles by 2 times.
2. It is used as a raw material for organic silicon polymer and in coatings that are resistant to high temperatures.
3. The application of nanosilicon powder to coatings can form a thin, film-like layer of nanosilicon particles. This is a widely used method 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 batteries is 4200mAh/g, which is higher than the carbon material.
6. On the nanosilicon substrate are ten types of nanosilicon particles/silicon dioxide nano-structures, which produce photoluminescence under forward bias or reverse bias in the main wavebands from near ultraviolet to near infrared. Photoluminescence, electroluminescence, and Luminescence models are proposed, which lay the groundwork for the realisation of silicon-based integrated optoelectronics.
Processing characteristics of nanosilica powder
Tongrun Information Technology Co., Ltd. manufactures nano-silicon powder products using the laser gas phase chemical plasma method. The product obtained this way has uniform silicon particles, high purity and low impurity, as well as good batch stability.
The majority of nano silicon powders used in the silicon carbon anode material at home and abroad are produced by ball milling and grinding with a Sand Mill. The output from a sandmill is low and batch stability is difficult to control. Also, the preparation process, which requires grinding and dry, is complex. Grading, Agglomeration and many other steps are done, but batch stability can’t be guaranteed. Sanding requires complex machinery and equipment. The production line is out of order and the investment required is huge.

5. Tongrun Information Technology Co. Ltd. offers a nano silicon powder that can be added to the lithium battery.

Packaging and Storage
This product should be kept in a cool and dry environment. It is packaged in anti-static inert gas packaging. It shouldn’t be exposed to the atmosphere for a prolonged period of time. Moisture can cause agglomeration, which will negatively affect the use and dispersion effect.
