The properties of the sphered quartz powder are excellent, with a large specific area, smooth surfaces, and high hardness.
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, the resin is incorporated into a smooth film, but the addition of resin to the mixture is not large.
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 spherical product is less than the one of the angull powder. Furthermore, it has the highest stress concentration and strength. 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.
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 spheral quartz dust is made from quartz stone. After its purification and ultrafine milling, it undergoes a high-temperature field so that the phase, crystal, and shape of the powder change instantly, from solid state to molten, to solid-state to solid-state. Methods for preparing sphere quartz powder include gas combustion flame and high-temperature plasma melt, injection, or high-temperature melting.
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.
Spherical quartz is used primarily in electronic packaging. However, it's also used extensively in the manufacture of advanced precision ceramics, precise grinding of optical components and inks as well as filler in special paints.
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: Vacuum packaging, 100g to 500g, 1kg/bag or 25kg/barrel. Or as requested.
