Introduction to Spherical Quartz siO2 Powder
Spherical powder of quartz
Also known as
Spherical silicon powder
Amorphous quartz is a powder of amorphous silica. The individual particles are spherical. It is white in color, with uniform particle sizes, good transparency, chemical and thermal stability, safety, insoluble in water, and has high levels of safety.
Quartz powder in spheres
It is used to make large-scale integrated circuit packaging. It is also used for high-tech applications such as aerospace, fine chemicals and daily cosmetics.
Physicochemical properties of Spherical Quartz SiO2 powder
Quartz powder in spheres
It offers the benefits of a smooth surface and large specific area.
First of all, the powder is fluid and can be stirred with resin to form an even film. The addition of resin is minimal and quartz powder is relatively large. The mass fraction can go up to 90.5%. The more quartz powder added to the mix, the lower its thermal conductivity. Additionally, the less thermal expansion coefficient the plastic sealing material has, the higher the performance of electronic components.
Second, the stress in spherical granules is less than that of angular granules. Also, the stress concentration and strength of plastic sealant made of spherical Quartz powder are the lowest and highest. When the integrated circuit chip has been encapsulated in spherical-pulverized plastic packing material, it yields a high yield and is very difficult to cause mechanical damage during transportation, installation and use.
Third, because the surface of the powder is smooth, it has a low friction coefficient, wear is minimal and molds can last for more than one time.

Spherical Quartz SiO2 Pulverization Methods
Flame melting method, plasma heating furnace technique, chemical synthesizer method, and hydrolysis are the most common methods to prepare sphere quartz powder.
1.
Flame melting method
The principle behind ball-forming is that high-temperature torch guns emit 1600-2000 high temperature flame. Once the powder is in the high-temperature area, its angular surface absorbs heat. This heat is transferred to the powder and the powder particles become completely molten. Surface tension causes the object to always move to the stable condition, while the spherical shape is the most stable, in order to accomplish the purpose of the product balls.
2.
Plasma heating furnace method
Hot plasma is also known locally as thermodynamic equilibrium plasma. The plasma’s main features include the temperature of the local electron, the ion and the gas (Tg). The thermal plasma category includes arc plasma, high-frequency and induction plasma.
High-frequency plasma melting is an efficient method of producing spherical quartz. The method uses moderate temperatures, stable control, high yield, and a high yield to achieve a higher level of spheroidization. Similar to the flame melting method, its principle and procedure are the same. The only difference is that the high temperature heat source is switched to a plasma generator.
3.
Chemical synthesis
The silica sol was heated up to form a silica gel. It was then treated with ammonia/ammonium bicarbose for spherical gel. It has low uranium and is easy for people to agglomerate.
4.
Hydrolysis is a method
The hydrolysate is mixed with the deionized water and different dispersants at constant speed. At the same time, the quartz rod is used to stir the hydrolysate with high speed. After washing, drying, and filtering, the hydrolysate has been dried, dehydrated to a constant weight in an oven at 100-200 degrees Celsius, and then transferred to the high temperature sintering furnace. High-temperature dehydroxylation at different temperatures can result in high-purity spherical quartz crystal powder.
Spherical Quartz SiO2 Pulverized for Applications
Quartz powder’s superior performance includes high dielectric, heat resistance and moisture resistance. It is also resistant to corrosion. It can be used as a substrate or packaging material in large-scale and very large-scale integrated Circuits.
Spherical quartz powder is also widely used in electronic Ink, optical Fiber, high grade precision ceramic manufacturing and optical devices. It can also be used as special paint coatings fillers.
