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.

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.
