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 flotation. Quartz powder is an inorganic, nonmetallic, nontoxic material that is non-toxic and odorless. It is also non-pollutible. Mainly used for large-scale integrated-circuit packaging, aerospace, aviation coatings, binders and catalysts. Medical, precision castings. 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 into production processes


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 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 formed from high-quality natural Quartz, but it is also a powder that is created by a unique process. The molecule structure is changed from a ordered to a disordered arrangement. 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 the silicon fine particles is modified with a material, such as silane. This increases the hydrophobicity of the silicon fine particles and improves their mechanical, electron, and chemical properties. The main purpose of surface-treatment of silicon fine powder is to improve performance of the filler.

As the technology industry continues to advance, species numbers will increase.
