Quartz powder summary Natural quartz (SiO2) or Fused Silica powder Powder is obtained by breaking (natural quartz high temperature melting, cooled SiO2), flotation (or vibration or airflow), 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 is also non-pollutible. Quartz powder is used mainly in integrated circuit packaging for large-scale, as well as in aerospace and aviation, coatings and paints, binders or catalysts, medical precision castings and high-voltage components, daily cosmetics. 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.

Divided by production process
Silicon fine powder is classified into crystalline, molten, square quartz, and active.
1. Crystalline silicon Powder
The powder is crystalline silica 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 crystalline silicone powder. 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 orderly to a chaotic arrangement. His color is white, has a high purity, and also has characteristics like: low line 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 high-purity silicon obtained by calcination at high temperatures can be permanently changed through rapid cooling. Its chemical properties are stable, it has a reasonable or ordered particle size distribution and is controlled. 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. The main purpose of surface-treatment of silicon fine powder is to improve the performance and efficiency of the filler.
As the technology industry continues to advance, species numbers will increase.
