Spherical quartz powder It is made by using a carefully selected, irregular-angled, silicon micropowder for the raw material. Then, it is shaped into a round shape with flame melting to get a silica powder that has a low stress, good fluidity, small specific surface, and a small amount of surface area.

Spherical Quartz Powder Properties

Spherical Quartz Powder has excellent properties including a smooth surface and a large surface area. It is also hard, stable, and has a high degree of chemical resistance.
First, the spherical granules are well-mixed with the resin and form a thin film. The resin content is low, while the quartz powder amount is high. This can result in a mass fraction of up to 90.5%. The more quartz powder that is added to the mold, the less thermal conductivity it has and the smaller its thermal expansion coefficient. The performance of electronic components is improved when they are closer to monocrystalline silicon’s thermal expansion coefficient.

Second, spherical quartz has the lowest stress and highest strength.

Finaly, the spherical shaped powder has a smooth, non-abrasive surface with a low coefficient of friction. It also wears the mold less, which increases its service life by a factor of two.

Spherical quartz powder applications

It has many applications. However, its main market is electronic packaging. Electronic packaging is an important industry that supports integrated circuits. The packaging requirements are increasing as integrated circuits get larger and more sophisticated.

Microelectronic packaging requires a high level of moisture resistance, low radiation, low stress and resistance to dip or reflow soldering. Also, the plastic seal must be good after the integrated circuit has been packaged. Spherical Quartz Powder is an essential support material for EMC. Not only does it need to have a particle size that meets the packaging range, but its purity and radioactive element content must also be low.

Quartz powder, which is spherical in shape, can be used for a variety of purposes, including electronic packaging. It can also be used as a filler in paints or coatings.
