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 and nontoxic material that is odorless, nontoxic, nonpollutible. It has many advantages, including its high temperature resistance, insulation, dielectric, filling capacity, low thermal conductivity coefficient, chemical stability, hardness and corrosion resistance. It 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 and high-voltage components, daily cosmetics, and other high tech fields. 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 epoxy floor with silicone fine powder and sealant silicon fine, as well as electron-level plastic, silicon grade powder, precision ceramics, and silicon powder.

Divided into production processes
Silicon fine powder can also be 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 three different grades: electronic grade crystalline silicone fine powder, general filler grade and high purity. 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 to a chaotic arrangement. His color is white, has a high purity, and also possesses the following properties: low expansion coefficient, good electromagnetic radiation, chemical stability, such as chemical corrosivity, reasonable or controllable distribution of particle sizes. Widely used is the range of fine silicon molten 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 the silicon fine particles is modified with a material like a silane. This increases the hydrophobic properties of silicon fines powders and improves the mechanical and chemical properties. Surface treatment of fine silicon powder particles improves the performance of filler systems.
As the technology industry advances, so will the number of species.
