Spherical Quarz SiO2 Powder Introduction
Spherical powder of Quartz
Also know:
Silica powdered sphere
Amorphous Quartz can be described as an amorphous type of quartz. Silica is its main ingredient. Silica is small round particles. Powder is light in color with uniformly sized particles.
Quartz powder in the form of spheres
It is used for large-scale, integrated Circuit Packaging packaging. This can be used in high-tech areas such as aerospace and fine chemicals.
Physical Characteristics of Spherical Quartz siO2 pulver
Quartz powder in the shape of spheres
The option to have a surface that is flat or with a particular material can be available.
You can combine the powder with resin to create a smooth coating. It is possible to combine quartz powder and resin into the mixture, but the result will be quite large. You can achieve mass fractions up to 90%. Higher amounts of filling can lower the thermal conductivity for quartz powders. The thermo expansion coefficient of plastic sealants is lower than that of quartz powders. The performance of electronic components can be affected by this.
Spherical powder has a stress level that is 60% less than angular. A second reason is the high strength and low stress levels of spherical Quartz powder plastic sealant. The spherical powder plastic packaging protects the integrated circuit chip. Because the packaging is made out of spherical powder quartz, mechanical damage cannot occur during transportation, installation or usage.
Powdered dust also has an advantage due to its non-sticky and smooth surface. You can also expect a longer shelf life.

Spherical Quartz SiO2 Pulverization Methods
Two of the most popular methods to make sphere quartz are flame melting and plasma heating furnace.
1.
Flame melting method
The basic concept behind ball-forming comes from high-temperature torch gun that can emit 1600-2500 flame temperatures. After the powder has been heated, its surface absorbs heat. This heat then causes the powder to melt. Finaly, the heat transfers to powder. The particles then become completely molten. The object will move in the same way as before, but surface tension will ensure it does so. Best is the stablest form.
2.
Plasma heating furnace method
The plasma is sometimes called hot plasma. The temperature at which electrons (Te), or ions, respectively are heated is one of the key characteristics of hot plasma. There are many types of thermal plasma.
Plasma melting at high frequencies is used for the manufacture of quartz crystal powder. It is safe and stable, has high yields, low temperatures, and a faster rate of spheroidization. Similar to flame melting, the principle and method of plasma generator is also identical. The plasma generator replaces heat from high temperatures.
3.
Chemical Synthesis
First, silica sol can be made into gel using ammonia/ammonium carbose. Acid was used to treat the gel for hydrated, spherical silica. By heating the silica powder, it was finally obtained. The product is very easy to mix and has a low amount of uranium.
4.
Hydrolysis is just one way to do it.
Combine the SiCl4 liquid, deionized water and mix well. Also, stir the hydrolysate using a quartz rod. After filtering the hydrolysate, you will dry it and then dehydrate it until it is equal in weight. It is then controlled at a temperature of 100 to 200. The material is heated in a furnace to be sintered. You can obtain extremely purified quartz particles with the right sizes through high-temperature crystal production and dehydroxylation.
Spherical Quartz SiO2 Application Pulverization
Quartz powder is highly resistant to heat, dielectricity, moisture and other factors. It is easy to mix and can be used as a filler.
Additionally, you can find spherical Quartz powder in electronic ink, optical fiber and many other optical devices. It can also be used in the production of special paint coat fillers.
