What is spherical Quartz Powder?

Spherical quartz powder is a good choice for its smooth surface, large specific area and high chemical stability. The first is that the spherical material has good fluidity. It can be mixed evenly with resin to form the film. Although the amount of resin used is minimal, the quartz powder filling volume can be high and may reach as high as 90.5%. The thermal conductivity of the molding compound will be lower if the quartz powder is used as a filler. The performance of electronic components that are produced is better when they are close to monocrystalline silicon’s temperature expansion coefficient. Second, the stress of the cylindrical powder is only 60% lower than the stress of angular powder. Furthermore, the plastic molding compound made with spherical Quartz powder has the lowest stress concentration, as well as the highest strength. The spherical material has a smooth, low friction coefficient and wear-resistant surface that can help extend the mold’s life.

Spherical quartz powder’s main applications

There are many uses for sphered quartz powder. Electronic packaging is its biggest market. Electronic packaging is the support industry for integrated circuits. As integrated circuits become more complex, the requirements for packaging materials are rising. Packaging forms are continually optimized and up-dated to meet these new requirements. The main components of electronic packaging include substrate materials, plastic materials, lead frames, and solder. Plastic packaging has grown rapidly because of its simplicity, cost-effectiveness, and ability to be mass produced. Plastic packaging is responsible for 95% global integrated circuits market.


Spherical silica powder is not only beautiful in form, but also has high chemical purity. It is able to meet the technical requirements of high end integrated circuits. It can be used to reduce the plastic packaging material’s thermal expansion coefficient and dielectric constant. The earth increases the product’s rigidity, weather resistance. impact resistance. tensile strength, moisture resistance and flame resistance. This makes it an essential component of electronic package design. In addition to its main use in electronic packaging, spherical Quartz powder can also serve as filler for special paints or coatings.
