Introduction to Spherical Quartz siO2 Powder
Spherical powder of quartz
Also called:
Spherical silicon powder
Amorphous quartz is an amorphous powder made of quartz. The main ingredient, silica, has individual particles that are round. This white powder has uniform particle sizes, high transparency, excellent chemical stability and thermal stability.
Quartz powder in spheres This is the main use of it for large-scale integrated Circuit Packaging packaging. It’s also useful in the high-tech industries of aerospace, fine chemicals and everyday cosmetics.
The Physicochemical Characteristics of Spherical Quartz SiO2 Pulver
Quartz powder in spheres It offers the benefits of having a flat surface and a high specific area.
First, the powder can be mixed with resin easily to create a smooth film. It is easy to add resin, but the quantity of quartz powder used in the mixture is quite large. A mass fraction of up to 90% can be achieved. A higher filling quantity of quartz powder will result in a lower thermal conductivity. Additionally, the thermo expansion coefficient of the plastic sealing materials is smaller. This affects the effectiveness of the components.
Spherical powder’s stress is 60% less than angular powder. Second, plastic sealing material made with spherical Quartz powder has the lowest stress concentration and highest strength. The integrated circuit chips are protected with plastic packaging material made of spherical quartz powder. This makes it difficult for mechanical damage to occur during transport, installation, or use.
A third advantage is the smooth surface of the spherical dust, which has low friction and wear. The mold’s service life is also extended.
Spherical Quartz SiO2 Pulverization Methods
Flame melting, plasma heating furnace and chemical synthesis are the most common methods to prepare spherical powder.
1. Flame melting method The basic principle behind ball-forming is that high-temperature torch guns emit 1600-2000 high temperatures of flame. Once the powder is in the zone of high-temperature flare, the powder’s angular surface absorbs heat. This heat then moltens it. Finally, the heat is transferred into the powder and the particles become completely molten. Surface tension causes the object to always move to the stable condition, while the spherical form is the best, in order to accomplish the goal of the product ball.
2. Plasma heating furnace method Known as hot plasma or local thermodynamic equilibrium plasma. The main characteristic of hot plasma is its temperature. The thermal plasma category includes arc plasma, highfrequency plasma, induction plasma, and hi-frequency plasma.
High-frequency plasma melting is used to make spherical powder of quartz. It uses a moderate temperature range, stability control, high yield, and can attain a higher rate of spheroidization. Similar to the flame melting process, its principle and processes are the same. However, the plasma generator replaces the heat source at high temperatures.
3. Chemical Synthesis To make silica powder, heat treated silica sol gel at a specific temperature with ammonia/ammonium bicarbose. This product is low in uranium, and it is very easy to agglomerate.
4. Hydrolysis is a method You will add the SiCl4 liquid to deionized water and mix it at constant speed. At the same time, the hydrolysate will be stirred with a quartz rod. After drying, washing, filtering and aging the hydrolysate, it is dehydrated to an even weight using a temperature control box between 100 and 200. It then goes to high-temperature sintering. You can get high-quality spherical quartz with the desired particle sizes by using high-temperature Sintering Dehydroxylation. Crystal shape conversions at different temperatures are also possible.

The quartz powder has a high level of dielectricity, heat resistance, moisture resistance and corrosion resistance. It is also highly fillable and low in cost.
Spherical quartz powder is also widely available in electronics ink, optical fibre, high quality precision ceramic manufacturing and other optical devices. It can also be used as special paint coat fillers.
