Spherical quartz powder It is made by using a carefully selected, irregular-angled, silicon micropowder for the raw material. This material is then shaped spherically through flame melting to produce a silica powder with low stress, a small specific surface, and good fluidity.

Spherical Quartz Powder Properties

Spherical Quartz Powder has excellent properties including smooth surface, large surface area specific, high hardness, and stable chemical property.
Firstly, 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, the stress on the spherical crystal powder is 60% less than the stress on the angular quartz powder. And the plastic molding material made from the spherical glass powder has the least concentration of stress and the greatest strength.

Finaly, the spherical shaped powder has a smooth, non-stick surface with a low coefficient of friction. It also wears the mold less, which increases its service life by more than ten times.

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 complex.

Microelectronic packaging requires a high level of moisture resistance, low radiation, low stress and good sealing after integrated circuits are 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.
