Spherical quartz powder
It is made by using a carefully selected, irregular-angled, silicon micropowder for the raw material. This material is then shaped into a round shape with flame melting to produce a silica powder that has a low stress, small specific surface, and good fluidity.
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 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 less thermal expansion coefficient. The performance of the electronic component produced is better if the thermal expansion coefficient of silicon monocrystalline is close to that of the molding compound.
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-abrasive surface with a low coefficient of friction. It also wears the mold less, which increases its service life by several times.
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, low radiation, resistance to dip-soldering and reflow-soldering, as well as good plastic sealing 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 is also widely used to produce optical fibers and high-grade cosmetics.
