Fused Silica Powder The material is high-quality fused sand crushed with a jet or vibration mill. It then undergoes classification. Performance-wise, it is characterized by a small coefficient of expansion, low stress and chemical corrosion resistance. Fused silicon has low radioactivity and good electrical radiation.

Where is fused silicon used in industry and why?

The silica powder, when mixed with a certain amount of silica, can be used to fill in the spaces between the cement particles. It will also form a solid gel with the hydration material and with the alkaline magnesium oxide. The following functions can be played by mortar, refractory castables and silica dust in cement-based concret:

Fused silica powder improves corrosion resistance.

2. Fused silicon powder can be used to reduce concrete pumping resistance by retaining water and preventing bleeding.

Concrete can be significantly improved by adding a layer of silicon powder.

The fusion of silicon powder can be used to reduce the dust that falls on concrete and castables sprayed and increase the thickness.

Fused silicon powder has been used in C150 Concrete Engineering as a key component for high-strength, lightweight concrete.

Use of fused silicon powder in concrete or low-cement castables can improve durability and reduce costs.

7.Fused Silicon Powder can effectively prevent the concrete alkali-aggregate reaction.

Castable refractories can be made more compact by adding fused silicon powder. The mullite is formed more easily when Al2O3 and silicon coexist. This improves the high temperature strength of the material.

Quartz powder summary Natural quartz (SiO2) or Fused Silica powder Powder is obtained by breaking (natural quartz high temperature melting, cooled SiO2). Other multi-channel processing methods include flotation, pickling, purification of high-purity drinking water, and other multichannel processes. Quartz powder is an inorganic nonmetallic nontoxic material that is non-toxic and odorless. It has excellent development potential because of its high temperature resistance, high insulation properties, high dielectrics, high filling characteristics, low thermal conductivity coefficient, hardness and corrosion resistance. Quartz powder is used mainly in integrated circuit packaging for large-scale, as well as in aerospace and aviation, coatings and paints, binders and catalysts, precision castings, high voltage components, daily cosmetics and many other high-tech areas. Due to its wide range of applications, it is rich. Divide Level
There are several types of silicon fine particles: common silicon fine, silicon grade powder for electronic applications, silicon grade powder for electrical purposes, silicon grade powder for molten silicon, ultrafine silicon grade powder and "spherical' silicon grade powder.

Divide by use
You can divide the silicon fine particles into paint coating, epoxy floor, silicone fine powder and sealant.

The production processes are divided into two categories:
Silicon fine powder is classified into crystalline, molten, square quartz, and active.
1. Crystalline silicon Powder
The crystalline silica powder This is natural high-grade quartz that has been produced through a unique grinding process without iron. Its color is white and pure. The process maturation has given it stable chemical and physical characteristics, along with a controllable, reasonable particle size distribution. The crystalline silica fine powder can also be classified into high purity, electronic grade and general filler grade. The crystalline fine powder is widely utilized.
2. Fused Silica powder
Fused Silica powder This powder is made from high-quality natural Quartz, but it is also a powder that is created by a unique process. In this case, the molecular structures are changed from an ordered arrangement to one of disorder. The powder is white in color, has a high purity, and also has characteristics like: low expansion coefficient, good electromagnetic radiation, chemical stability, such as chemical corrosivity, reasonable or controllable particle sizes. Widely used is the range of molten fine silicon powder.
3. Fang Shiying silicon
Fang Shiying is a silicon powder made by a unique, high-quality process using natural quartz. The crystal structure of the high-purity silica can be permanently changed by rapid cooling after calcination at high temperatures. Its chemical properties are stable, its particle size is controlled, and it has a reasonable or orderly distribution. It is widely utilized.
4. Active silicon fine powder
The surface of silicon particles is treated with silane to improve the hydrophobic properties. This also enhances the chemical and mechanical properties of the mixture. Surface treatment of fine silicon powder particles is to improve performance of filler system.
As the technology industry continues to advance, species numbers will increase.
