What is spherical Quartz Powder?

Spherical quartz powder is a good choice for its smooth surface, large specific area and high chemical stability. The first is that the spherical material has good fluidity. It can be mixed evenly with resin to form the film. Although the amount of resin used is minimal, the quartz powder filling volume can be high and may reach as high as 90.5%. The thermal conductivity of the molding compound will be lower if the quartz powder is used as a filler. The performance of electronic components that are produced is better when they are close to monocrystalline silicon’s temperature expansion coefficient. Second, the stress of the cylindrical powder is only 60% lower than the stress of angular powder. Furthermore, the plastic molding compound made with spherical Quartz powder has the lowest stress concentration, as well as the highest strength. The spherical material has a smooth, low friction coefficient and wear-resistant surface that can help extend the mold’s life.

Spherical quartz powder’s main applications

There are many uses for sphered quartz powder. Electronic packaging is its biggest market. Electronic packaging is the support industry for integrated circuits. As integrated circuits become more complex, the requirements for packaging materials are rising. Packaging forms are continually optimized and up-dated to meet these new requirements. The main components of electronic packaging include substrate materials, plastic materials, lead frames, and solder. Plastic packaging has grown rapidly because of its simplicity, cost-effectiveness, and ability to be mass produced. Plastic packaging is responsible for 95% global integrated circuits market.

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 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 of spherical Quartz powder are the lowest and highest. It is therefore difficult to damage the integrated circuit chips during transport, installation and use if the integrated circuit chip has been encapsulated in spherical packing material made of spherical quartz powder.
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 The principle behind ball-forming is that high-temperature torch guns emit 1600-2500 high temperature flame. Once the powder is in the high-temperature area, its angular surface absorbs heat. This heat is transferred to the powder inside, 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 product’s purpose.
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 Te, the ion Ti 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 plasma generator is switched from a high-temperature heat source.
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 different dipersants at constant speed. The hydrolysate can then be stirred 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.

What is spherical Quartz Powder?

Spherical Quartz Powder, also known by spherical Silica powder, is an amorphous powder of quartz that has particles that are spherical in form and whose main constituent is silicon dioxide.

Spherical quartz is used primarily for copper clad laminations and epoxy mold compound fillers in large scale integrated circuit packaging. However, it also has applications across high-tech areas such as aerospace, fine chemicals, and everyday cosmetics.

Why is Quartz Powder Spheroidized

1. The ball has a small surface area, isotropy, fluidity, and filling quantity. It can have a mass ratio of 90.5%. The filling speed of silica micropowder can be increased.

The filling rate for silicon micropowder is higher, but the plastic sealing compound’s thermal expansion coefficient is lower. The thermal conductivity of the plastic sealing material is also lower, so it is more similar to monocrystalline silicon. This will improve the performance of electronic components.

2. The strength and stress concentration of the plastic sealing compound made from spherical dust is the lowest. The plastic sealing compound made of spherical is stronger than the one made from angular. It has a stress level of 0.6. When the integrated circuit chips are encapsulated by the spherical dust plastic sealing compound, the yield is high. However, it is difficult to cause mechanical damage during transportation, installation and use.

3. Spherical powder’s friction coefficient is low, so the mold wear is very minimal. The mold also has a long service-life. The service life of the mold is doubled when compared to angular powder. The cost of plastic sealing compound packaging molds is high. It is therefore necessary for some to be imported.

4. Silicon micropowder has the ability to strengthen epoxy resin. Spherical powder can also enhance this effect.

What is it? Spherical Quartz Powder ? Spherical quartz powder, made from quartz stone, is obtained after purification. Amorphous powder is made from irregularly angular particle into regular spherical particles.
The key features of Spherical Quartz Powder
Spherical quartz powder offers the benefits of a smooth surface and large specific surface area. It also has high hardness and stability. First, the spherical material is very fluid. The resin is mixed evenly with it to form a film. The greater the amount of quartz powder used to fill the mold, the lower its thermal conductivity. Also, the thermal expansion coefficients of the molding compound are smaller. And the higher the thermal expansion of single-crystalline silicon, the better the electronic components will perform. The stress of spherical granules is less than half that of angular powder. Furthermore, the mold compound made of spherical granules has the lowest stress concentrations and highest strength. Finally, the surface of spherical quartz powder is smooth. The friction coefficient is low and the wear on molds is minimal. This can help extend the mold’s life expectancy by up to one-third.
