What Advantages does Spherical Silica Powder Have?

What Is Silica Powder? Silica Powder is composed of natural quartz (also known as fused quartz), and is prepared by crushing, grinding fine, classification and acid treatment.

Silica is an example of silicon dioxide, with the chemical formula SiO2. It is one type of silica and is used in many organisms. The main ingredient of sand is silica. The most abundant and complex family of materials that includes silica is made up of many mineral compounds and synthesized products. fused-quartz and aerogel are just a few examples.

It can be used to make structural materials and microelectronics, which are electrical insulators.

What Is Spherical Silica Pulp?

Spherical powder features a flat surface, large surface area and strong chemical properties.

First, the powder is very fluid. The resin can be stirred evenly into a thin film. It is easy to add resin, but the quartz powder filling quantity is large. A mass fraction of up to 90% can be achieved. A higher filling quantity of quartz powder will result in a lower thermal conductivity. Additionally, the thermo expansion coefficient of the plastic sealant material is less. However, monocrystal silica thermal expansion coefficient can be correlated with the temperature of quartz. These factors affect the quality of electronic components.

Second, the stress for spherical granules is 60% less than that of angull powder. The stress concentration in plastic seals made with spherical Quartz powder is lowest, while the strength is highest. Final, the surface quality of spherical quartz powder is extremely smooth. The friction coefficient and wear are low, as well as the mold’s service life.

For what purpose is Spherical Silica Powder used?

These materials are used primarily as electronic packing materials. Three main components of electronic packaging materials are: substrate, plastic sealing material, lead frame and solder. The advantages of plastic packaging include its simplicity, cost-effectiveness, affordability, and mass production. Plastic packaging currently accounts for over 95% of all integrated circuits worldwide. EMC (epoxy plastic package) is the mainstay of integrated circuit packaging. More than 95% use epoxy plastic sealants for their microelectronic components.

The main requirements for integrated circuit packaging are low humidity resistance, low stress and dip resistance. They also require good sealing performances. Inorganic fillers must be used in epoxy resin. The most common inorganic additives are currently quartz powder. Microelectronics has seen rapid advancement, making large-scale integration circuits more difficult to manufacture. Quartz powder serves as an important support for EMC materials. Not only does it conform to the specific scope of the EMC material, but also meets the requirements of high purity radioactive elements and low levels of radioactivity, particularly when designing the particles to meet the required spherical specifications.

It is a good-looking powder of silicon, with high purity chemical elements and low levels of radioactive elements. This allows it to be compatible with high-end embedded circuits. The product can significantly reduce the temperature expansion coefficient of plastic sealing materials, lower its dielectric constant, increase stress and greatly improve rigidity.

Spherical Quartz Powder can be used not only in electronic packaging but also in high-grade cosmetics, precision ceramics, precise grinding of opto devices, electronic components and filler for special paint coats.
