What Is Spherical Alumina ()?
Spherical Alumina It is, therefore, a type of alumina that has a spherical morphology. The crystal phase is a-alumina.Why should we emphasize the “spherical” shape? The reason is that the area of application for alumina products can become too large, and performance in many areas of application is closely tied to the size and morphology of raw powder particles. Spherical particles can have different shapes but have the following characteristics: a smaller surface area, greater bulk density, better fluidity and a more regular morphology.
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 is used in
1. As a ceramic material
Spherical Alumina This is a very important property for high-quality ceramic products.
You can avoid scratches using spherical-alumina polishing abrasives.
3. It is used in the petrochemical sector
Higher requirements for the distribution of pore sizes and the structure of the carrier alumina are being made in the Petrochemical Industry. You can adjust the configuration of the particles to alter the size distribution and size of the spherical Alumina Powder.
4. To act as catalyst
Directly using spherical aluminum as a catalyst may reduce abrasion, increase service life and lower production costs.
5. For surface protective coating
Spherical powder particles of sphere-shaped oxide are sprayable on metals, plastics, and other materials. They can improve surface hardness and corrosion resistance as well as wear resistance and resistance to fire.
6. Materials that are luminescent
Alumina powder shaped into spheres has high bulk density. This can help reduce scattering from the luminous bodies, reduce lost light and improve light transmission.
7. This is used in the electronic industry
Because of the outstanding characteristics of spherical aluminum in terms of electrical, thermal and physical properties, it is extensively used in the area of semiconductor electronic packaging.
