What fields can the fused silica powder be used in?

What are the characteristics of fused silica powder and what field is it usually used in?

Fused silica powder is a kind of silicon dioxide powder material which is produced by grinding, grading and impurity removal process with fused silica, glass and other materials as the main raw materials. It has the characteristics of high purity, high insulation, low coefficient of linear expansion, low internal stress and excellent motor performance.

Due to its high purity, low dielectric constant, dielectric loss and coefficient of linear expansion, molten silicon powder is superior to crystalline silicon powder in signal transmission speed, transmission quality and reliability of electronic products. It can be used in copper clad laminate used in smart phones, automobiles, network communication and industrial equipment, and in integrated circuit packaging of air conditioners, washing machines, refrigerators, charging piles, photovoltaic modules, etc In the field of adhesive, coating, ceramics, encapsulation materials and so on.

The other spherical silica powder is a kind of spherical silica powder material, which is processed by flame melting method with selected angular silica powder as raw material. It has the advantages of small specific surface area, good mobility and low stress.

Compared with angular silicon micro powder, spherical silicon micro powder has better surface activity and higher filling rate, which can significantly reduce the linear expansion coefficient of copper clad laminate and epoxy plastic sealant and improve the reliability of electronic products. At the same time, spherical silicon micro powder can reduce the wear of equipment and mold in the manufacturing of related products, which can be applied to copper clad laminate for aerospace, radar, computer, 5g communication, etc In the board; in the epoxy molding materials for the packaging of large-scale integrated circuits such as smart phones, digital cameras, flat panel displays, processors and switches; and in the fields of coatings, special ceramics and fine chemicals.
