Spherical Alumina Powder And The Applications of Spherical Alumina

One of the thermal conductive material is aluminum.

Spherical aluminum oxide

It is now a “star product”. Spherical alu is a popular choice in areas such as thermal management and vehicles that consume high amounts of energy, 5G, and other newer energy vehicles. 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 Al2O3 Property

Because of their many crystal shapes and unique chemical and physical properties, Alumina and its Hydrate are used widely in electronics, petrochemical industries, refractories ceramics papermaking pharmaceuticals aerospace, and other fields. Alumina’s application capabilities in many areas are directly related to their morphology. The Al2O3 powders of different sizes have different morphologies. However, the Al2O3 spheres are more uniform in morphology.

Spherical Application

Used as Spherical Allumina Powder

Material that conducts heat
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 filler spherical alumina can be found in many thermal interface materials. It has a thermal conductivity up to 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 smoothed, which will prevent scratches from the workpiece’s surface and improve polishing.

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 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.
