Spherical Quartz Powder – Properties and Applications |


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 low friction.


Spherical Quartz Powder Properties

Spherical quartz powder is characterized by its smooth surface and large surface area. It also has high chemical stability.

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.

The stress of the powder spherical is 60% lower than the stress of an angular, so the compound plastic made with spherical Quartz powder has the lowest stress concentration and highest strength.

The powder’s smooth surface and low friction coefficient can reduce wear to the mold. These factors will help extend its service life.


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, low radiation and resistance to dip and reflow soldering. It also needs to perform well in plastic sealing 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 optical lenses, as well as special paints and coatings fillers.
