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, chemical stability and thermal stability, safety, as well as insoluble in water.
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 The advantages include a smooth surface and large specific area. They also have high hardness and stability.
First, the spherical particles have good fluidity. They can mix resin with it to form a smooth film. The resin can be added in small amounts, but the amount of quartz powder used for filling is substantial. 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 in angular granules. Also, the stress concentration and strength of plastic sealant made from spherical Quartz powder are the lowest and highest. Because the yield of the integrated circuit chip is high when it is sealed with spherical packing material made from spherical quartz powder, mechanical damage is very difficult 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, plasma heating furnace and chemical synthesis are the most common methods of making spherical powder.
1. Flame melting method Ball formation is achieved by using a high temperature flame gun that emits 1600-2000 high temperatures flame. The powder then absorbs heat from the flame and becomes molten. This heat is transferred to the powder inside, which is 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 can also be called local thermodynamic equilibrium or hot plasma. The plasma’s main features include the temperature of the local electron, the ion, and the gas (Tg), which are all almost identical. 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 : Silica sol emulsion at a specific temperature was treated using ammonia/ammonium bicarbose. The gel was then treated with acid to obtain hydrated, spherical, silica. Finally, the gel was refined and heat-treated in order to obtain spherical, silica powder. It has low uranium and is easy for people to agglomerate.
4. Hydrolysis is a method : Add the liquid SiCl4 and deionized water with various dispersants to the hydrolysate at a constant speed. Then stir the hydrolysate with a quartz rod at 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 in large or very large-scale integrated systems as a packaging material and substrate.
Spherical quartz powder is also widely used in electronic dyes, optical fiber, precision ceramic manufacturing, electronic components of precision grinding, electronic inks, and special paint coatings.
