What is Spherical Quartz SiO2 Powder?

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, thermal stability and 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 This product has many benefits, such as a smooth surface and large specific area. It also has stable chemical properties.
First, the spherical 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 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-powder 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, and chemical synthesis are the most common methods for 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 is also known locally as thermodynamic equilibrium plasma. The plasma’s main features include the temperature of the local electrons (Te), ions (Ti), or 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 : 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 heated-treated to obtain spherical, silica powder to meet customer needs. 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.

Spherical Alumina Powder And The Applications of Spherical Alumina

One of the thermally conductive material is aluminum. Spherical aluminum oxide It is now a “star product”. High-energy consumption areas like new energy vehicles, 5G, and thermal management encourage the use of spherical. This is why the market for spherical alu continues to grow. Spherical Alumina is widely used not only as a thermal conductive substance but also in advanced ceramics, catalysis and grinding, polishing and composite materials.

Spherical Property

Because of their many crystal shapes and unique chemical and physical properties, Alumina and its Hydrate are used widely in the areas of electronics, petrochemical, refractories ceramics papermaking pharmaceuticals aerospace, and other fields. Alumina’s application capabilities in many areas are directly related to their morphology. The Al2O3 powder particles that are spherical have the best properties. Their morphology is regular, has a lower specific surface area and greater packing density, as well as better fluidity. This can significantly improve product performance.

Spherical Application

Used as Spherical Allumina Powder Thermal Conductive Materials The most significant use of spherical aluminum is thermal conductive material. Spherical alumina can be classified as thermal interface material, thermal-conductive engineering plastics and thermally conductive plastic sealing substances. The thermal interface materials can be used to IC packaging or electronic heat loss. These materials fill in any gaps caused by contact between the materials. This reduces the heat transfer resistance and improves heat dissipation. Inorganic thermal fillers such as sphered aluminum are common. Its thermal conductivity can reach 3042W/m K.

Ceramics using Spherical Allumina Powder
The properties of ceramics can be greatly affected by adding a small amount of spherical aluminum powder to their production. Low temperature brittleness in ceramics has a significant impact on their ability to be used for various purposes. For low-temperature plastic ceramics, you can use ceramic materials with spherical aluminum powder. Additionally, ceramics can be made tougher by using spherical-alumina. It can increase the ceramics’ strength and decrease the melting temperature by reducing the amount of spherical allumina powder to 5.0%.

As a polishing agent, use Spherical Allumina Powder
Spherical or flake-alumina alumina offers better fluidity and dispersion than conventional granular or flake. Because spherical powder abrasives are evenly distributed within polished products, there is no possibility for powder to accumulate in large quantities. The particle surface can also be smooth, which helps avoid scratches and improves polishing.

Spherical Led luminaire Use Both its catalyst and its transporter
High chemical activity is possible because of the large amount of unsaturated chemical bonding and catalytic activ centers that are found on the surface. Spherical Alumina offers the benefits of high chemical activity, low wear, and long service lives. It also boasts a large specific area. It is impossible to replace the performance and characteristics of the catalyst made of spherical aluminum with other materials.

Spherical Alumina Use in 3D printing
Due to its strong strength, high spheroidization rate and resistance to high temperatures, 3D printing is a popular use of sphered-alumina. The advantages of spherical allumina powder include high solid content and good fluidity. They also have high mechanical and chemical properties.

The Properties And Application of Spherical Alumina

What exactly is Spherical Alumina, and how can it help you? Spherical aluminum refers to a form of alumina having a spherical shape. The type of crystal phase it has is called -alumina. Why should we emphasize the “spherical” shape? The reason is that the area of application for alumina is too large, and performance in many areas of application is directly affected by the size and morphology of raw powder particles. Spherical powder particles can have different shapes but have regular morphology. A smaller specific area, higher bulk density, better fluidity and a greater application performance. Spherical aluminum is one of the finer chemical products in the alumina family. It is capable of compress molding and sintering ceramics with outstanding quality. The regular morphology is also good for grinding and polishing materials. In the petroleum industry it can be used to catalyze superfine, spherical, and aluminum powder. This can decrease wear and prolong the product’s service life, thus lowering production costs. Spherical Alumina can be used in the following: 1. As a ceramic material Spherical Allumina exhibits excellent compression molding characteristics and sintering capabilities, making it a great choice for high-quality ceramic products. 2.
