The silicon powder manufacturer is made of natural quartz (silica) or fused quartz (amorphous silica after high-temperature calcination, fusion and cooling of natural quartz) or alkali-free glass, which is crushed, crushed, sieved and classified, and then spheroidized production. The fine powder for grinding and flotation is produced through a variety of processing technologies, such as separation, gravity separation, magnetic separation or acid leaching purification, washing, dehydration, drying, powder grinding (or vibration grinding, jet milling, etc.), airflow classification Wait for many processing micro powders.

Silica powder is a non-toxic, odorless, and pollution-free white inorganic non-metallic mineral material. Because it has excellent physical properties, extremely high chemical stability, unique optical properties and reasonable and controllable particle size distribution; and also has good high temperature resistance, acid and alkali corrosion resistance, poor thermal conductivity, high insulation, and expansion rate Low, stable chemical performance, high hardness and other excellent characteristics, so it is widely used in optical glass, electronic packaging, electrical insulation, ceramics, paint coatings, precision casting, silicone rubber, medicine, cosmetics, electronic components, ultra-large integrated circuits and microelectronics, Mobile communications, notebook computers, aviation, aerospace and other production fields. Silicon powder is also an important raw material for the production of polysilicon, which is the main raw material for solar cells. With the rapid development of China's high-tech and new materials, the use of silicon powder in my country is increasing. Will become larger and larger, and the application areas will become wider and wider.

According to the production process and combining the characteristics of raw materials, according to the production process and raw material characteristics, silicon powder can be divided into: crystalline silicon powder, fused silicon powder, composite silicon powder, cristobalite silicon powder and active silicon powder.

The above is the common-sense problem of silica powder manufacturers that the editor tells you. You can understand the simple description. The content is for reference only. If you want to know more inquiries, please feel free to contact our manufacturer.
