Overview of Nano Silicon

/ / no Comments

Nano silicon The term crystalline silicon is used to describe particles that are smaller than 5 nanometers in diameter. Nano silicon powders are characterized by their high purity, fine particle size and uniform distribution. It is non-toxic with a large surface, high surface activity and low bulk density. Nano-silicon powder is a novel generation of optoelectronic semiconducting materials, with a wide gap energy semiconductors. It is also an extremely powerful light source. The main uses of nano-silica powder
The organic silicon polymer is made from organic matter.
The metal silicon is purified into polysilicon.
Metal surface treatment;
Use graphite or nanocarbon powder as anode in lithium batteries to increase their capacity;

Preparation of nano silicon
Nano silicon is prepared by using coarse silicon in the current Nano materials. The millimeter scale coarse silicon is generally crushed down to less than 100 microns, and then ground with a nanometer level using a sandmill. The grinding medium is used to rub, impact and shear the material in this method.
Application of nanosilicon in the floor industry
Nano-silicon The material is a full-water, inorganic mortar. This product is resin-based, and can therefore be used in conjunction with resin products. Nano-silicon products can penetrate concrete and are matched to cement and quartz. This ensures a very strong adhesion with the original substrate, and no cracking or delamination. It is an essential material for modern floors products.

The Applications of Nano Silicon Powder

/ / no Comments

Overview Nano Silicon Powder
The most promising electrode material for next generation lithium-ion batteries is silicon. Its specific capacity (3600mAh/g) is more than 10 times that of graphite (372mAh/g). The material's significant expansion (more than 300%) in loaded (lithiation), and the instability of its solid electrolyte interface (SEI) make it a restricted choice. Poor mechanical stability and chemical passingivation properties make silicon electrodes difficult to cycle. There has been a lot research into these issues and many suggestions for ways to overcome them.
The volume of silicon changes during lithium insertion. It is about 400%. When this happens, the silicon cracks and falls from the collector. The prototype battery loses most of its capacity in a few charge-and-discharge cycles. Lithium-ion silicon's stability and capacity issues are the keys to the success of large-capacity, high-capacity batteries.
Anode materials made of silicon have great potential to improve the efficiency and energy storage capacities of lithium-ion cells. The main drawback of silicon anode materials was their surface passivation via oxidation. This is a process that increases impedance while decreasing the circularity. High-purity silicon materials are capable of achieving high specific capacity without significantly affecting their cycle life.

What is Nano Silicon Powder?

/ / no Comments

Introduction to Nano Silicon Powder Silica Si powder (smoky grey superfine powder) is a smoky, super-fine powder. The color of silica Si powder will vary in shade depending upon how much carbon it has. Silica powder's whiteness is between 40-50. It has a bulk density around 200kg/m3. The true density is 2.2g/cm3. Nano silicon powder This refers to crystalline silica particles less than 5 Nanometers in diameter (billionths off a meter).

Nano Silicon Powder preparation
There are three methods of preparing the ingredients. nano silicon powder Mechanical ball milling, chemical and vapor deposition, as well as plasma evaporation, condensation. The industrial production of silicon powder in western countries began earlier. There are specialized silicon products companies such as Chemicalbook of Japan and DuPont of the United States. The company can use plasma evaporation, condensation and other methods to produce high-quality nano silicon powder in different particle sizes. It is the most advanced production technology in the world.

Nano Silicon Powder: Applications
1. Can be used to produce nano silicon wire for rechargeable lithium-carbon anode materials or nano spherical silicone powder surfaces coated with graphite. It can enhance the electric power and charge/discharge cycle times of rechargeable lithium batteries up to three times.
2. Can be used in high-temperature resistant coatings and other refractory materials. It reacts with organic matter as the raw material in organic silicon polymer substances.
3. The coating can be applied to form nano silicon particle films, which are widely used in solar power.
4. Mixing nano-spherical diamond powder and silicon under high pressure creates nano-sic – diamond composite materials. These materials can be used for cutting to increase strength and toughness.
5. Nano-silicon is used as an anode material in lithium-ion battery batteries. The theoretical specificity of nano-silicon, or nano-silicon carbon, is higher than that of carbon.
6. The silicon nanoparticle substrate was used to design more than ten types silicon nanoparticle/siliconoxid nanostructures. These nanostructures achieved photoluminescence in major band from near ultraviolet to near-infrared as well as low threshold voltage electroluminescence. Forward or reverse bias was applied.

Researches and application prospects of nano silicon powder

/ / no Comments

What is Nano silicon? Nano silicon The smallest diameter of crystal silicon particles is 5 nanometers. Nano silicon powder is high in purity and has small particles. It also has uniform distribution. This product is tasteless and non-toxic thanks to its high surface area, high activity and low bulk density. Nano silicon powder, a new generation optoelectronic materials with high gap energy semiconductors, is also a high power light source material.
Nano silicon research is undergoing new developments
(1) Change the amount of silicon-rich and annealing conditions to control the size or density of silicon nanocrystals. The critical temperature required for the formation of silicon nanocrystals has been suggested by the literature as being 1000oC. We have proved this through experiments. After annealing at 900oC, the high-resolution electron photo of silicon-rich silicone oxide has a silicon content of around 30%. It is obvious that silicon nanocrystals exist.
(2) First time observation of the electroluminescence in Au/(Ge/SiO2) superlattice/p–Si structures. High-resolution electron micrograph showing a four-period Ge/SiO2 supra lattice. The bright-line shows SiO2 having a thickness of 2.0nm. The Ge layer has a thickness at 2.4nm.
(3) The nanoSiO2/Si/SiO2 single-potential high-potential sandwich structure was created on a silicon substrate. It was produced using magnetron-sputtering technology. This allowed for visible electroluminescence. The changes in the thickness (W), which affects the Nano-silicon layer, cause the peak position and intensity for electroluminescence to oscillate synchroeously. Further research and analysis have proven that the oscillation time is 1/2 of the de Broglie wavelength. This is explained by the electroluminescence theory proposed by our group.

(4) Er electroluminescence (with a wavelength 1.54mm) was first realized using the SiO2 :Si Er film grown by magnetron-sputtering.
(5) First time, a UV-violet luminescence of 360nm at a low threshold voltage was achieved in heat-treated natural silicon oxide/pSi. It is the longest wavelength known to be produced by silicon-based ultravioletescence.
The applications prospects for Nano silicon
We have developed more than 10 types of silicon/siliconoxide nanostructures and realized the photoluminescence within the main wavelength bands (including 1.54mm to the near infrared) and the photoluminescence with the Forward or Retro bias Low threshold Voltage Electroluminescence. Furthermore, we proposed widely supported photoluminescence as well as electroluminescence models that provide the foundation for silicon-based optoelectronic Integration. It has significant scientific significance and great application potential.
