What is spherical quartz powder?

Spherical quartz powder has excellent properties such as smooth surface, large specific surface area, high hardness and stable chemical properties. First of all, the spherical powder has good fluidity and is evenly mixed with the resin to form a film. The amount of resin added is small, the filling amount of quartz powder is high, and the mass fraction can reach up to 90.5%. The higher the filling amount of quartz powder, the lower the thermal conductivity, and the smaller the thermal expansion coefficient of the molding compound. The closer to the thermal expansion coefficient of monocrystalline silicon, the better the performance of the electronic components produced. Secondly, the stress of the spherical powder is only 60% of the stress of the angular powder, and the plastic molding compound made of spherical quartz powder has the least stress concentration and the highest strength. Finally, the spherical powder has a smooth surface, low friction coefficient, and low wear on the mold, which can prolong the service life of the mold by more than one time.

The main application areas of spherical quartz powder

Spherical quartz powder has a wide range of applications, and its use as an electronic packaging material is the largest market in its application field. Electronic packaging is the supporting industry of integrated circuits. With the development of large-scale and very large-scale integrated circuits, integrated circuits are becoming more and more sophisticated, and the requirements for packaging materials are getting higher and higher, and the packaging forms are continuously optimized and updated. The three main materials of electronic packaging are substrate materials, plastic packaging materials, lead frames and solder. Due to its low cost, simple process, and suitable for mass production, plastic packaging has developed rapidly since its inception, and its share of packaging is increasing. At present, plastic packaging accounts for 95% of the integrated circuit market in the world. 


Spherical silicon powder is not only good in shape, but also has high chemical purity and low content of radioactive elements. It can meet the technical requirements of high-end integrated circuits. Its application can greatly reduce the thermal expansion coefficient of the plastic packaging compound, reduce its dielectric constant, and reduce stress. The earth enhances the rigidity, abrasion resistance, weather resistance, impact resistance, compression resistance, tensile resistance, moisture resistance, and flame resistance of the product, so that the product has good arc resistance insulation characteristics and UV radiation resistance, etc., and has become an electronic package Indispensable key material. In addition to being mainly used in the field of electronic packaging, spherical quartz powder can also be widely used in the manufacture of electronic inks, optical fibers, high-grade cosmetics, high-grade precision ceramics, precision grinding of optical devices and electronic components, and as fillers for special paints and coatings.
