About Silicon Nanoparticles Nano Si Powder:

Silicon nanoparticles (SiNPs)

They are compatible with biological systems and have no metal content.

Silicon nanoparticles

These are pure amorphous, nanosilicon dioxide. It has a particle size of less than 5 Nanometers. The range of particle sizes is also very small.

Nano silicon powder

It is an innovative generation of optoelectronic materials that have wide gap energy semiconductors. This material is also high-power light source material.

Silicon nanoparticles

These are known to be absorbent and abrasive. However, mesoporous silica nanoparticles play an important role in drug delivery and nanomedicine.

Silicon nanoparticles

These materials have received a lot of attention over the years due to their fascinating physical properties, unique photoluminescence, and biocompatibility.

It is simple.

Silicon Nanoparticles Nano Si Powder produced


Reverse microemulsion, flame synthesis and commonly used sol-gel are some methods that can be used to create silicon nanoparticles. A reverse microemulsion is a process where surfactant molecules are dispersed in an organic solvent to create spherical micelles. When water is present, the polar heads groups form microcavities that are water-containing. They are commonly called reverse micelles.

The addition of silicon Alkoxide to the solution containing the reverse micelles is a controlled process that allows the creation of silicon nanoparticles. However, the main problems with reverse micro-emulsification are their high costs and difficult removal of surfactant from the finished product.

A stirred reactor at 90degC produces 65g of nano-silicon by reacting 1kg sulphuric acids 3M and 190g Olivine. Silicon produced has a surface area between 100 and 500 m2/g, an average particle size of 5-20 nanometers, and a surface area in micropores that is 20 to 200 m2/g.

Silicon Nanoparticles Nano Si Pulse:

1. Material to make a lithium battery anode

A silicon nanoparticle made from nano Si powder can be used in anode materials for rechargeable lithium batteries. Alternatively, the top of nanosilicon powder is coated using graphite. This improves the battery’s electric power by over 10 Capacity as well as the ability to withstand multiple charge-discharge cycles.

2. The nano-silicon semiconductor light emitting material

The silicon substrate can be used to create nanostructures made of silicon/silicon oxide. These structures are capable of photoluminescence as well as forward and reverse bias at all wavelength bands, including 1.54 and 1.62um.

3. Aluminum castable

Si powder will reduce the creep of casting castings made of high-aluminum aluminum in furnaces at high temperatures. Additionally, it can prevent cracks from creeping the furnace lining.

4. Fabric compound made from tire cord material

Silicon nanoparticles can be added to tire cord fabric compounds. This will increase the vulcanizate’s 300% constant stress, tear strength, Mooney viscosity and give the compound a strengthening effect.


Silicon nanoparticles can enhance the protection against aging, scratch resistance and anti-staining of the coating. They also extend the durability of the coating.

Shipping and Packing of Silicon Nanoparticles Nano Sil Powder
