What is Silica Powder and How Does It Work? Quartz powder (or silica) is made from quartz (natural quartz, fused quartz), by crushing, cleaning, acid treating, crushing, fine grinder, and classification. Iron and other processing are also used to produce the powder.

Silica is a form of silicon oxide. Its chemical formula is SiO2, and it is the most common type of quartz found in nature. Silica is the major component of sand. Silica, which can be formed as a variety of mineral compounds or synthetic products, is one of the most complex materials. fused-quartz, silica, aerogel, and vapor silica are just a few examples.

It is used as a structural material, microelectronics, and in components of the food and pharmaceutical industries.

What is Spherical Silica Pulp?

Spherical quartz dust offers a smooth surface and large specific area. It also has stable chemical properties.

First, the spherical powder is fluid and evenly mixed into a resin film. The resin addition volume is low and the quartz powder filling is large. The mass fraction can exceed 90.5%. The lower the quartz powder filling, the lower its thermal conductivity. Additionally, the plastic sealing materials’ thermal expansion coefficients are smaller. The closer they are to monocrystal silica thermal expansion coefficient, the better electronic components can be produced.

Second, the stress in spherical powder can be 60% lower than that in angular powder. Furthermore, the stress concentration for plastic seals made from spherical Quartz powder is the lowest, while its strength is the greatest. Finally, spherical powder has a smooth surface, a small friction coefficient, low wear, and a longer service life.

What is Spherical Silica Powder Used For?

Most often used as packaging materials . The main materials for electronic packaging are plastic sealing material, substrate material, and lead frame. Because plastic packaging is low-cost and easy to make, it has seen rapid development. Plastic packaging now accounts for more than 95% worldwide’s integrated circuit market. EMC (epoxy plastic packaging) is the mainstay of integrated circuit packaging. More than 95% use epoxy plastic sealing.

The main requirements for integrated circuit packaging are low moisture resistance and low stress. They also need to resist reflow welding and dip resistance. Inorganic fillers must be used in epoxy resin. The most common inorganic additives are currently quartz powder. Microelectronics industry is rapidly developing, and large-scale, very big-scale integrated circuits are more difficult to manufacture. Quartz powder, which is important support for EMC materials, not only conforms to specific scope requirements, but also meets the high purity, low-content radioactive elements demands, especially in terms of the particle shape.

Spherical silica powder has a great shape and can be used to meet the technical requirements of high end integrated circuits. It can significantly reduce the thermal extension coefficient of plastic sealing material, reduce it’s dielectric constant, decrease stress, greatly increase rigidity and wear resistance as well as compressive resistance, impact resistance.

In addition to its use in electronic packaging, spherical Quartz Powder can be used extensively in the manufacture and precision grinding of electronic devices and components.
