High Purity Spherical quartz powder Spherical SiO2,99.9%

About Spherical Quartz Powder Spherical SiO2
Spherical quartz The powder's excellent qualities include a flat surface, large specific area and high stability. First, powder has excellent properties. Spherical powder fluidity It is excellent, and resin is thoroughly mixed to form a smooth film. However, because the resin addition is so small, it is easy for the filling quantity of quartz powder It is extremely high and can exceed 90.5%. A higher filling quantity of quartz powder means a lower thermal conductivity. Also, the plastic sealing material's thermal expansion coefficient is smaller. The closer the thermo expansion coefficient for monocrystalline silicon is, the more efficient the electronics components will perform. A second advantage is that the stress level of the spherical powder can be 60% less than the one of the angulous powder. Furthermore, the strength and stress concentration of plastic sealants made from spherical Quartz powder are the best. Final, the surface quality of the spherical quartz powder is very smooth. The friction coefficient and wear are low, which means that the mold's service life can be increased by up to 1 time.

It is simple. Spherical Quartz powder produced?
The spherical quartz powder is made out of quartz stone. After its purification and ultrafine milling, it undergoes a high-temperature field so that the phase, crystal, and shape changes instantaneously. It is currently possible to prepare it using high-temperature plasma melt, high-temperature melting injection, or gas combustion flame.

Applicaciones Spherical Quartz powder :
Spherical sio2 quartz powder is most commonly used for high temperature silicone rubber, silicon defoaming agent and advanced printing ink.
Spherical silica is a good form, with high chemical purity and low radioactive elements, it can meet all the technical requirements for high-end integrated systems. The application of this powder can significantly reduce the thermal expansion coefficient of encapsulation materials, decrease stress and increase rigidity, wear resistance and weather resistance. Products that have good insulation properties and resist to ultraviolet radiation are now the essential key components of electronic packaging materials.
The main use of sphere quartz powder in electronics packaging is to make electronic ink and optical fiber. It can also be used for the production of high-end cosmetics, electronic ink and precision grinding optical components and optical devices.

Storage Conditions of Spherical quartz Powder Spherical SIO2
Spherical siO2 powder should be stored in dry, cool, and closed areas. This will prevent moisture from oxidizing and affecting dispersion performance.

Transport and packing of Spherical siO2 powder
You can pack it in two plastic bags with the inside.
