The Difference Between Microsilica Powder And Microsilica Powder Is Analyzed in Detail

In the actual transaction process, many manufacturers regard silicon powder as micro-silicon powder, but because of the essential difference between the two, there is often a deviation in the transaction process, which makes the product indicators provided by the manufacturer and the index parameters of the demand side very different.
The difference in appearance between microsilica powder and microsilica powder
In terms of appearance, silicon powder and micro-silicon powder are basically relatively easy to distinguish. Silicon powder is a non-toxic, tasteless inorganic nonmetallic material with pure quality, white color and balanced particles. According to the different silica raw materials, reducing agents or furnace conditions, the vast majority of micro-silica powder is gray or dark gray. In the process of formation, due to the effect of surface tension during the process of phase transformation, amorphous spherical particles are formed, and the surface is relatively smooth, and some are the agglomeration of multiple spherical particles stuck together. White microsilica powder is rare and limited in quantity.
Differences in properties and uses between microsilica powder and microsilica powder
From the performance or effect of silicon powder and micro-silicon powder: silicon powder has good temperature resistance, acid and alkali corrosion resistance, poor thermal conductivity, high insulation, low expansion, chemical stability, high hardness and other excellent properties. According to its use, silicon powder is divided into the following categories:
1, ordinary silicon powder, mainly used in epoxy resin castable, potting material, welding electrode protective layer, metal casting, ceramics, silicone rubber, coating and other chemical industry.
2, electrical grade silicon powder, mainly used in ordinary electrical insulation casting, high voltage electrical insulation casting, APG process injection material, epoxy potting material, ceramic glaze and so on.
3, electronic grade silicon powder, mainly used in integrated circuits, electronic components of plastic sealing materials and packaging materials.
4, molten quartz powder (WG) used raw materials are natural quartz after high temperature melting, cooling amorphous SiO2, through the process of processing of micro-powder. The product has high purity, low thermal expansion coefficient, low internal stress, high moisture resistance, low radioactivity and other excellent characteristics. Mainly used in large scale and very large scale integrated circuit for plastic sealing material, epoxy castable, potting material, and other chemical fields.
5, ultrafine quartz powder, mainly used in coatings, paints, engineering plastics, adhesives, rubber, casting ceramics.
6, nano SiOx, as an important member of nanomaterials, is mainly used in electronic packaging materials, polymer composite materials, plastics, coatings, rubber, pigments, ceramics, adhesives, glass fiber reinforced plastic, drug carriers, cosmetics and antibacterial materials and other fields, has become a new material for upgrading traditional products.
