What are the specific characteristics of silicon powder?

Crystalline silicon powder has always been one of the excellent products of our company. Today, Xiaobian is going to talk about the silicon powder.

Common sense of silicon micro powder industry: silicon micro powder is made of natural quartz (SiO2) or fused quartz (amorphous SiO2 after high-temperature melting and cooling of natural quartz) by crushing, ball milling (or vibration, air flow grinding), flotation, acid washing purification, high-purity water treatment and other processes. Silicon powder is a non-toxic, tasteless and pollution-free inorganic non-metallic material. Because of its excellent properties such as good temperature resistance, acid and alkali corrosion resistance, poor thermal conductivity, high insulation, low expansion, stable chemical properties and high hardness, it is widely used in chemical industry, electronics, integrated circuit (IC), electrical appliances, plastics, coatings, advanced paints, rubber, national defense and other fields. With the rapid development of high technology, silicon powder will enter a new historical development period.

Generally speaking, we can divide silicon micro powder into several kinds: Ordinary silicon micro powder, electrical silicon micro powder, electronic silicon micro powder, molten silicon micro powder, ultra-fine silicon micro powder, "spherical" silicon micro powder. Among them, ordinary silicon powder is mainly used in epoxy castables, potting materials, electrode protective layer, metal casting, ceramics, silicone rubber, coatings and other chemical industries.

The electrical grade silicon powder is mainly used for the insulation casting of ordinary electrical parts, high voltage electrical appliances, APG process injection material, epoxy potting material, high-grade ceramic glaze and so on.

Electronic grade silicon powder includes integrated circuits, plastic packaging materials and packaging materials for electronic components.

The raw material of fused silica powder (WG) is amorphous SiO2, which is melted by natural quartz at high temperature and cooled, and then processed by multiple processes. The product has high purity, small coefficient of thermal expansion, low internal stress, high humidity resistance and low radioactivity.
