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, classification, and iron processing to meet the requirements for powder.
Silica is a form of silicon oxide. Its chemical formula is SiO2. In nature, it is the most common type of quartz. 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 of all, the resin is evenly mixed into a thin 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?
Mainly used to make electronic packages. The main components of electronic packaging materials are plastic sealing material, substrate material, and lead frame. Plastic packaging has seen rapid development since its inception. This plastic packaging account for an increasing amount of packaging. More than 95% of all integrated circuit market share is held by plastic packaging. 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. 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 encapsulate specific scopes but also meets the requirements of high purity radioactive elements.
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, weather resistance. fire resistance.
In addition to its use in electronic packaging, spherical Quartz Powder can be used extensively in the manufacture and processing of high-grade optical ink, high-grade precision clays, precision grinding optical devices and electronic parts, as well as in filler for special paint coats.
