Crystalline quartz powder is a great choice because of its smooth surface and large specific area. It also has high stability chemical properties.
About Spherical Quartz Powder Spherical SiO2
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
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. The spherical powder's stress is less than the angular, so the strength and stress concentration of plastic sealing material made of spherical Quartz powder are the same. 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.

Performance of Spherical quartz powder Spherical siO2
1. You can add high sphericity to uniform size but the viscosity is not affected.
Technical Parameter Spherical quartz powder Spherical siO2
2. The surface of spherical silica oxide is fluid, with uniform film formation when stirring with resin. There's little resin used, and it has high fluidity. A lower thermal conductivity is better for electronic components. It will also reduce the thermal expansion coefficient.
3. Spherical silicon dioxide-filled plastic is used to encapsulate the integrated circuit chips. The yield is good, the friction coefficient is low, and mold wear is minimal. This makes the mold last a very long time. It is possible to improve the mold performance over angle powder. You can double the life expectancy.
It is simple.

The sphere quartz powder is made out of quartz crystal after ultrafine milling and purification. This causes the phase, crystal, and shape to change instantly from solid to liquid state to solid-state. The most common methods of preparation are high-temperature plasma melt, high-temperature melting injection, and gas combustion torch method.
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 and precision ceramics.
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.
Packaging of Spherical Quartz Powder Spherical SiO2 powder: Vacuum packaging, 100g to 500g, 1kg/bag and 25 kg/barrel. Or as you request.
