What is spherical Quartz Powder?

Spherical quartz powder is a good choice for its smooth surface, high specific area and excellent chemical properties. First, the spherical material is very fluid and can be mixed evenly with resin to form an even layer. 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 the monocrystalline silicon thermal expansion coefficient. The stress of the powder spherical is 60% lower than the stress of the powder angular. Furthermore, the strength and stress concentration of the plastic molding compound made with spherical Quartz powder are the lowest and best. Finally, the spherical material has a smooth, low friction coefficient and wear on the mold which can increase the mold’s life expectancy.

Spherical quartz powder’s main applications

There are many uses for sphered quartz powder. Electronic packaging is the biggest market in this application area. 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 materials for 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. Today, 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 and abrasion resistance. It also reduces impact resistance, weather resistance. compression resistance, moisture resistance and flame resistance. This makes it an essential key material for electronic packages. In addition to its main use in the field electronic packaging, spherical Quartz powder can also widely be used in the manufacturing of high-grade cosmetics. High-grade precision ceramics. Precision grinding optical devices and electronic components.
