High Purity Spherical quartz powder Spherical SiO2,99.9%

The 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, the resin is incorporated into a smooth film, but the addition of resin to the mixture is not large. 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 has a smaller thermal expansion factor. This affects the efficiency of electronic components. Second, the stress level of the spherical powder can be 60% less than the angular, so the strength and stress concentration of plastic sealing materials made 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.

It is simple. Spherical Quartz powder produced?
The sphere quartz powder is composed 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. At the moment, preparation 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 to make high temperature vulcanized Silicon 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 widely used in electronic packaging. It can also be used extensively in the manufacture of advanced precision ceramics, precise grinding of opto-mechanical devices, and as a filler in special paints or coatings.

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 reducing the performance of the product.

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 25kg/barrel. Or as you request.
Delivery of Spherical siO2 Powder and quartz powder After receipt of payment, items may be shipped by air or sea as soon as they are possible.
