Quartz powder in spheres
The silica powder is made with a selection of irregular-angled silicon nanopowder. This raw material was then flame melted into a spherical form to produce a small, specific area, high fluidity, low stress, and high flexibility.
Spherical Quartz Powder Properties
Spherical quartz powder is a great choice because of its smooth surface and large specific area. It also has high stability chemical properties.
First, the powder is fluid and evenly mixes with the resin. This creates a film. It is easy to add resin, but the amount of quartz powder used is very large. The mass fraction can even reach 90.5%. A higher amount of quartz powder is used to fill the mold, which results in a lower thermal conductivity. Also, the thermo expansion coefficient of the compound will be smaller. A better performance is achieved by electronic components if the thermo expansion coefficient for monocrystalline silicon is close to it.
Additionally, the stress level of the spherical granular powder is less than 60%, so the plastic molding compound made with spherical Quartz powder is both the strongest and has the lowest stress concentration.
Finally, the smooth, non-sticky surface of the spherical dust can increase the mold’s life expectancy by reducing friction and wear.
Spherical quartz powder applications
It has many applications. Electronic packaging is its largest use. Electronic packaging is an industry that supports integrated circuits. As integrated circuits become increasingly sophisticated and larger-scale, very large-scale, or even extremely large-scale, they require more packaging material. Packaging forms and specifications are continually optimized and improved.
Microelectronic packaging requires it to exhibit high levels of moisture resistance, low stress, resistance to dip and reflow soldering as well as good plastic sealing properties after integrated circuits are packaged. The important EMC support material, Spherical Quartz Powder, requires that the particles are the correct size.
Apart from being used in electronic packaging, spherical Quartz Powder can also be used to make high-grade cosmetics and precision ceramics. It is also used as a filler for coatings and paints.
