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 the following properties: Spherical powder fluidity It is excellent, and resin is uniformly mixed 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. 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 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.

It is simple. Spherical Quartz powder produced?
The spheral quartz dust is produced from quartz stone that has been purified and then ultrafine ground. This causes the phase, crystal, and shape of the powder 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.

Applicaciones Spherical Quartz powder :
Spherical sio2 quartz powder is most commonly used to make high-temperature silicone rubber. It can also be used as a silicone defoaming agent.
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 the area of 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 powder: Vacuum packaging, 100g to 500g or 1kg/bag at 25kg/barrel. Or as you request.
Delivery of Spherical siO2 Powder and quartz powder Shipments could be made by sea or air as soon as payment receipt is received.
