About Silicon Nanoparticles Nano Si Powder:
Silicon nanoparticles (SiNPs) These quantum dots, which are free of metal and have a biocompatible surface, can be customized in size or luminescence. Silicon nanoparticles The particles are pure, amorphous nanosilicon dioxide. The particle diameter and particle range are both less than 5 nanometers. Nano silicon powder This is a novel generation of optoelectronic semiconducting materials that have wide gaps and are also high-power light sources.

Silicon nanoparticles Mesoporous Silicon Nanoparticles are important in drug delivery, nanomedicine, and other applications. Silicon nanoparticles The unique physical properties of these materials, their active surface state, photoluminescence, biocompatibility and distinctive photoluminescence have drawn a great deal of attention over the past decade.

What is Silicon Nanoparticles Nano Si Powder produced ?
Reverse microemulsion, flame synthesis or the widely used Sol-gel are all methods for synthesizing silicon nanoparticles. In a microemulsion reverse, surfactant molecule dissolved within an organic solvent forms spherical micelles. In the presence or water, polar head group organizes itself to form microcavities containing water.

In order to synthesize silicon nanoparticles in reverse micelles, it is possible to carefully control the addition of the silicon alkoxide catalyst to the medium. The cost of reverse micro emulsification and the difficulty in removing surfactant are its main drawbacks.

By reacting 1kg of sulphuric acids 3M with 190g Olivine at 90degC, 65g of Nano-silicon are produced. The silicon produced is characterized by a specific area of 100-500m2/g, an average particle size of 5- 20 nm, and a specific area in micropores ranging from 20-200m2/g.

Nano Si Powder Application:

1. Anode materials for lithium batteries
Anode materials of rechargeable Lithium batteries are made with silicon nanoparticles, which are produced from nano Si powder. Or, the surface of nano silica powder is coated in graphite, improving the capacity by over 10 and the number of charge-discharge cycles.
2. Nano-silicon semiconductors light-emitting material
Silicon/silicon-oxide nanostructures, designed on a substrate of silicon, can achieve photoluminescence or forward bias (including 1.54 and 1.62um), from near-ultraviolet through to near-infrared.
3. Aluminum castable
The addition of Si powder in high temperature furnaces reduces the creep rate, which can lead to cracks or spalling on the furnace lining caused by shrinkage and creep. It also improves the service life.
4. Tire cord fabric
Addition of silicon nanoparticles in the tire cord fabric can increase 300% constant tensile stresses, tensile characteristics, tear strength, decrease Mooney viscosity and have a certain strengthening effect on the compound.
5.Coatings
By adding silicon nanoparticles, the coating can be made more resistant to aging, staining and scrubbing, as well as have better anti-aging and scrub-resistant properties.
