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 has high purity and high dispersion. It also has a uniform distribution, a large specific surface, high surface activity, a low bulk density, optimum activity, and enables large industrial output. Nano silicon powder may be mixed 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 wide gap.

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. 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-silicon carbide–diamond composite is formed by mixing the 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 batteries is 4200mAh/g, which is higher than the carbon material.
6. Ten types of nano-silicon particle/silicon dioxide nano-structures on the nanosilicon substrate are designed, which achieves photoluminescence under forward bias or reverse bias in the main wavebands from near ultraviolet to near infrared. Photoluminescence and Electroluminescence Models, which lay the groundwork for the realisation of silicon-based integrated optoelectronic systems.
Processing characteristics of nanosilica powder
Tongrun Information Technology Co., Ltd. manufactures nano-silicon powder products using the laser gas phase chemical plasma method. This produces nano-sized silicon particles with high purity and low impurity levels, as well as good batch stability.
Most nanosilicon powders used in silicon-carbon anode materials are produced by ball milling and grinding with a Sand Mill. The output from a single mill is very low, and it is difficult to control the batch stability. Also, the preparation process, which requires grinding and dry, is quite complex. Grading, Agglomeration and many other steps are done, but batch stability can’t be guaranteed. The sanding procedure is complex and involves a large amount of equipment and machinery. The production line is out of order and the investment required is huge.
