The purpose of the silicon powder

Silicon powder (Microsilica or Silica Fume), also called micro silicon powder, scientific name "Silica Fume, also known as Silica Fume, is an industrial electric furnace in the process of high temperature silicon and ferrosilicon smelting industry, along with the waste gas emitted by special capture device to collect smoke. Scientific name "silicon ash", Microsilica, or Silica Fume, is an industrial electric furnace in the process of high temperature silicon and ferrosilicon smelting industry, along with the waste gas emitted by special capture device to collect smoke. In the escape of smoke, SiO2 accounted for about 90% of the total ash content, granularity is very small, the average particle size is almost nanoscale, known as the silicon powder.

The specific use of all kinds of micro silicon powder is as follows: 1. The silicon powder, the main purpose for epoxy resin protective layer castable, potting materials, welding electrode, metal casting, ceramics, silicon rubber, coatings and other chemical industry. 2. Electrical grade silica powder, main use for insulation pouring of ordinary electric parts, high-voltage electrical insulation pouring, APG process injection material, epoxy potting compound, high-grade ceramic glaze, etc. 3. The electronic grade silicon powder, the main purpose is mainly used for integrated circuits, electronic encapsulation materials and packaging materials. 4. Molten Shi Yingwei powder, raw material used in melt Shi Yingwei powder (WG) is a natural quartz by the high temperature melting, cooling after amorphous SiO2, through multi-channel process of micro powder. The product high purity, small thermal expansion coefficient, low internal stress, high moisture resistant, fine properties such as low level. For large and very large scale integrated circuit encapsulation material, epoxy castable, potting compound, and other chemical fields. 5. The superfine Shi Yingwei powder, main use Is mainly used in coating, paint, engineering plastics, adhesives, rubber, kratos senior ceramic precision casting. 6. Nano SiOx, nano SiOx, as an important part of the nanometer materials, mainly used in electronic packaging materials, polymer composite materials, plastics, coatings, adhesives, rubber, paint, ceramics, glass fiber reinforced plastic, drug carrier, cosmetics and antibacterial materials and other fields, has become a traditional product of upgrading of new materials.
