What Advantages does Spherical Silica Powder Have?

What is Silica Powder and How Does It Work? Quartz powder (or silica) is made from quartz (natural quartz, fused quartz), by crushing, picking up, cleaning, acid treating, crushing, fine grinding 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 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 the electronic components that will 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?

Mainly used to make electronic packages. Substrate material, plastic sealing material, and lead frame/solder are the main materials used in electronic packaging. Plastic packaging has seen rapid development since its birth. The current global market for integrated circuits is 95% because of 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 stress, low moisture, low alpha radiation, dip resistance, reflow weldability, and low humidity. Inorganic fillers must be used in epoxy resin. Quartz powder is the most common inorganic material. 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 and low radioactive elements demands, especially when it comes to the shape of the particles using the spherical requirements.

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 and reduce stress. Also, it can increase the rigidity. Tensile resistance, compression resistance, weather resistance. Fire resistance.

This powder can be used for electronic packaging as well as in the production of high-grade optical ink, precision ceramics, precision grinding optical devices, and electronic components.
