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 properties, they have been widely used in many areas, including electronics, petrochemical, refractories as well as papermaking and pharmaceuticals. Alumina’s application capabilities in many areas are directly related to their morphology. The Al2O3 powders of different sizes have varied morphologies. Spherical particles can exhibit a more regular structure, smaller surface areas, higher packing density, and greater fluidity. This is able to greatly enhance the product’s application potential.

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 filler spherical alumina can be found in many thermal interface materials. Its thermal conductivity is approximately 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 that have spherical aluminum powder. Additionally, ceramics can be made tougher by using spherical-alumina. It can increase the ceramic’s toughness by reducing the sintering temperatures and if the powder contains 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 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. High specific area, low wear and long service lives are some of the benefits that spherical Alumina offers. It is impossible to replace the catalyst and carrier made of spherical aluminum.

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 spherical alumina. The advantages of spherical allumina powder include high solid content and good fluidity. They also have high mechanical and chemical properties.
