Application:

1) Ordinary silicon powder:

It is used in epoxy resin castable, potting material, protective layer of welding electrode, metal casting, ceramics, silicone rubber, coating and other chemical industries.

 

2) Electrical grade silicon powder:

It is used for insulation pouring of ordinary electrical parts, insulation pouring of high-voltage electrical appliances, APG process injection material, epoxy potting material, high-grade ceramic glaze, etc.

 

3) Electronic grade silicon powder:

It is mainly used for plastic sealing and packaging materials of integrated circuits and electronic components.

 

4) Fused quartz powder: 

the raw material of fused quartz micro powder is amorphous SiO2 of natural quartz after high-temperature melting and cooling, which is processed by multi-channel process. the product has high purity, low coefficient of thermal expansion, low internal stress, high moisture resistance and low radioactivity. It is used for plastic sealing materials, epoxy castables, potting materials for large-scale and ultra large-scale integrated circuits, and other chemical fields.

 

5) Ultrafine quartz powder:

Mainly used in coatings, paints, engineering plastics, adhesives, rubber, precision casting, high-grade ceramics.

 

6) Nano silicon powder:

It belongs to nano materials, which are mainly used in the fields of electronic packaging materials, polymer composites, plastics, coatings, rubber, pigments, ceramics, adhesives, FRP, drug carriers, cosmetics and antibacterial materials. It has become a new material for upgrading and upgrading traditional products.

the function of micro silicon powder is mainly used in mortar and concrete, wall decoration materials and other building materials and industrial materials, as well as some special uses, such as anti caking agent in chemical fertilizer industry.
