What is Silica Powder and How Does It Work? Quartz powder (or silica) is made of pure quartz.
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 (as a electrical insulator), and in components of the food and pharmaceutical industries.

What is Spherical Silica Pulp?
Spherical quartz dust has many advantages including a smooth surface and large specific surface 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 thermal expansion coefficients of plastic sealing materials 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 of angul powder. Furthermore, the stress concentration of the plastic seal made from spherical Quartz powder is the lowest, while the strength is highest. 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?
These materials are used primarily as electronic packing materials. Substrate material, plastic sealing material, and lead frame/solder are the main components of electronic packaging. Plastic packaging has seen rapid development since its inception. The current global market for integrated circuits accounted for over 95% of plastic packaging’s market share. This is due to its simplicity, cost effectiveness, and mass production. 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, low stress and dip resistance. Reflow welding is also an option. Inorganic fillers must be used in epoxy resin. At present, quartz powder is the most common inorganic ingredient. Microelectronics industry is rapidly developing, and large-scale, very big-scale integrated circuits are more difficult to manufacture. Quartz powder is used as an important support for EMC materials. Not only does it conform to specific scope requirements, but also meets the high purity, low-content radioactive elements demands, especially when it comes to the shape of the particles.

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.

In addition to its use in the field electronic packaging, spherical Quartz Powder can also widely be used in high-grade cosmetics, high precision ceramics, precision grinding optical devices, and electronic components and as a filler for special paint coats.
