High Purity Spherical quartz powder Spherical SiO2,99.9% | TRUNNANO

Posted on 2023-04-14 By admin

Powdered spheres of quartz have excellent physical properties, including a flat surface and large area.
Purity: 99.9%

Shape: Spherical

Size: 300nm


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 has a smaller thermal expansion factor. The more the thermo expansion coefficient for monocrystalline silicon is, the better electronic 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 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.

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.

Spherical Quartz powder


produced?


The spherical quartz powder is made out of quartz stone. After its purification and ultrafine milling, it undergoes a high-temperature field so that the phase, crystal, and shape changes instantaneously. 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.

The excellent shape of sphere silica powder can not only meet all the technical requirements of high-end integrated systems, but also reduces the thermal expansion coefficient of encapsulation materials, decrease stress and increase rigidity, wear resistance and weather resistance. Products with high arc resistance insulation properties and ultraviolet radiation resistance have been deemed indispensable 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, electronic ink and precision grinding optical components and optical devices.


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 or 1kg/bag at 25kg/barrel. Or as you request.

Delivery of Spherical siO2 powder and quartz powder


Could be shipped by sea, air or express once payment has been received.


Technology Co. Ltd. (), is a trusted supplier and manufacturer of chemical material. We have more than 12 years experience providing high-quality chemicals, Nanomaterials and other super-high quality chemicals.
