Quartz powder in spheres
The silica powder is composed of a selection of silicon micropowder with irregular angles. This raw material was flame-melted into a spherical form to produce a small, specific area, high fluidity, and low stress.
Spherical Quartz Powder Properties
Spherical quartz powder is characterized by its smooth surface and large specific area. It also has high levels of hardness, stability chemical properties, and high durability.
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 whose thermal expansion coefficients are close to those of monocrystalline silicon.
The stress of the powder sphere is 60% lower than the stress from the powder angular. Furthermore, plastic compound made with spherical Quartz powder has the lowest stress concentration and highest strength.
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, precision ceramics, electronic inks, electronic components and precision grinding, as well fillers in special paints or coatings.
