Spherical quartz powder It is made from carefully selected irregularly angled silicon micropowder. It is then processed by flame melting into a cylindrical shape to produce a silica powder with a low stress, small specific surface, and high fluidity.

Spherical Quartz Powder Properties

Spherical Quartz Powder has excellent properties including a smooth surface, a large specific surface area as well as high hardness.
The powder is fluid, and it mixes evenly with the resin. This forms 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 less thermal expansion coefficient. The performance of electronic components is improved when they are closer to monocrystalline silicon’s thermal expansion coefficient.

Second, the stress on the spherical grains is only 60% the stress on the angular grains. And the plastic molding compounds made with spherical quarts powder have the least concentration of stress and the greatest 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 at least one time.

Applications for Spherical quartz powder

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 complex.

Microelectronic packaging requires a high level of moisture resistance, a low level of stress, sensitivity to alpha radiation 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 radioactivity 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.
