Silica Powder

The silica powder is an important raw material for the production of polysilicon. Silica powder reacts with anhydrous hydrogen chloride in a fluidized bed reactor. It generates trichlorosilane.
Silica fume is a fine silica powder material generated in the smelting of ferrosilicon alloy and industrial silicon. The process produces the SiO2 and Si gas.
Activity of silica powder (coupling agent) filled natural rubber, butadiene rubber, rubber compound, the powder is easily dispersed, the performance of the mixing process, rolling and extrusion is very good, and can increase the curing rate of vulcanizates for rubber to enhance the viscous effect, especially ultra-fine grade silica powder, replace part of the silica fill in the rubber compound, are very good role for improving the physical indicators of the products and reduce production costs.
The 'Global and China Silica Fume Powder Market - Industry Analysis, Size, Share, Growth and Forecasts 2016-2021' is a professional and in-depth study on the current state of the global Silica Fume Powder industry with a focus on the Chinese market.
Micro-silica fume, also known as silica fume, silicon powder, in the smelting of the silicon alloy or industrial silicon, silicon vapor is discharged through the flue after oxidation, obtained by the special design of the precipitator collection of amorphous, powdered silica. 
According to metal powder supplier, different milling method of silica fume activity is differentiated, what determine the active factors have: powder on the microstructure, surface area, particle size, surface protection and equipment steel consumption.
The silica sol is a colloidal solution of silica fine particles dispersed in water, also known as silica sol, or silica hydrosol. 
According to metal powder supplier, add silicon powder can change some of the important physical performance of concrete, silica particles can be filled with a relatively greater porosity of the cement particles, reduce the pore volume, but the silicon powder’s specific surface area on the workability have a great impact. 
Silicon powder also called micro silica fume, scientific name is "silicon fume", also known as silica fume, is an industrial furnace in high temperature smelting industrial silicon and ferrosilicon process, with exhaust gas escaping smoke through a special collection device collection and processing to obtain.
Because of high absorption rate of nanometer silica fume and lithium battery, nanometer silica fume can significantly improve capacity of lithium battery. Nanometer silica fume and graphite can become alternatives of nano toner as raw materials.
From a comprehensive perspective, the effect of silica fume to improve the durability of concrete is the most significant, and can be used for almost any durability requirements of the environment. Impermeability, generally, the effect of silica fume increased impermeability is greater than the increase of strength,silicon powder mixed with a small dosage of low-strength concrete. 
Recently, silica fume prices have raised. In the market, resource of high-quality silica fume (silica content is more than 90%) constraints and the international market has continuous expanding demand for micro-silica fume.
Because of the great attention of environmental protection, many countries require that electric furnace flue of silicon and industrial silicon ferroalloy should be released after removing dust. In this way, the silica fume increased, and it encourages people to find ways for silica fume application.
Silica particles are extremely fine, compared with other powder materials, its specific surface area is up to 20000-280000cm2/g, about 50 times greater than the fly ash, about 50 to 100 times greater than concrete. 
Titanium is a metal element, below 0.83mm titanium particles are called titanium powder. Titanium powder can be divided into pure titanium powder, alloy titanium powder, titanium hydride powder, metal titanium powder, sponge titanium powder, titanium nitride powder, titanium carbide powder.
