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.



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.


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.
