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, 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 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 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 of angul powder. Furthermore, the stress concentration in a plastic seal made of spherical Quartz powder is the lowest, while the strength is highest. The surface of spherical dust is smooth, the friction coefficient and wear are small, and the mold’s life span can be extended to more than one-hundred years.
What is Spherical Silica Powder Used For?
Primarily used as packaging materials . The main materials for electronic packaging are plastic sealing material, substrate material, and lead frame. Plastic packaging has seen rapid development since its inception. The current global market for integrated circuits accounted for over 95% of all 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, low alpha radiation, dip resistance, reflow weldability, and low stress. 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 encapsulate specific scope 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, decrease stress, greatly increase rigidity and wear resistance.
Spherical quartz can be used for electronic packaging. However, it can also widely be used in the production of high-grade optical ink, precision ceramics, precision grinding optical devices and electronic parts, as well as filler in special paint coats.
