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 evenly stirred to form a film. However, because the resin addition is very small, filling is minimal.
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. Second, the stress level of the powder is less than the one of the powder in angular form. Furthermore, the strength and stress concentration of plastic sealed material from spherical Quartz powder are the best. Final, the spherical quartz powder has a smooth and low friction coefficient. The mold wear is also minimal, so 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.
2. This surface is spherical in silicon oxide and has good 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.

Spherical Quartz powder
produced?
The sphere of quartz is made from 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. These methods are high-temperature plasma melt, high-temperature melting injection, and gas combustion torch method.
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 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 or 1kg/bag at 25kg/barrel. Or as you request.
Delivery of Spherical siO2 powder and quartz powder
Shipping by express, air or sea can all be arranged as soon as payment is received.
