Among the many thermal conductive materials, spherical aluminum oxide has become a "star material".High energy consumption fields such as new energy vehicles and 5G promote the application of spherical alumina in the field of thermal management, the demand for spherical alumina is increasing, and the market continues to expand. In addition to being used as a thermal conductive material, spherical alumina is also widely used in advanced ceramics, catalysis, grinding and polishing, composite materials and so on.
Spherical Al2O3 Properties
The numerous crystal forms and unique physical and chemical properties of alumina and its hydrate determine that they are widely used in the fields of electronics, petrochemical industry, refractories, ceramics, abrasives, papermaking, pharmaceuticals, aerospace and so on. The application properties of alumina products in many fields are closely related to the morphology and size of raw material powder particles. Among the powder particles of different shapes, the spherical Al2O3 particles have regular morphology, smaller specific surface area, larger packing density and better fluidity, which can greatly improve the application performance of the products.
Spherical Alumina Powder Applications
Spherical Alumina Powder used as Thermal Conductive Material Thermal conductive material is the most important application of spherical alumina. As a thermal conductive material, spherical alumina is divided into thermal interface materials, thermal conductive engineering plastics, thermal conductive aluminum-based copper clad laminates, thermal conductive plastic sealing materials and so on. Thermal interface materials are materials used for IC packaging and electronic heat dissipation, which can fill the micro-gaps caused by the combination or contact of the two materials, thus reducing the impedance formed in the process of heat transfer and improving heat dissipation. Spherical alumina is a common inorganic filler in thermal interface materials, and its thermal conductivity is up to 30~42W/ m K.
Spherical Alumina Powder used in Ceramics Adding a certain amount of spherical alumina powder in the production process of ceramics will change the properties of ceramics to a great extent. The low temperature brittleness of ceramics greatly affects the application range of ceramics. Ceramic materials with spherical alumina powder can be used to make low temperature resistant plastic ceramics. In addition, spherical alumina can greatly improve the toughness of ceramics. When the content of spherical alumina powder is 5.0%, it can effectively improve the toughness of ceramics and reduce the sintering temperature.
Spherical Alumina Powder used as Polishing Abrasive Compared with traditional granular or flake alumina, spherical alumina has better dispersion and fluidity. Spherical alumina powder abrasives can be evenly distributed in the polished products, the phenomenon of abnormal accumulation of powder will not occur, and the particle surface is smooth, which can avoid scratches on the workpiece surface, so as to improve the finish of the polished surface.
Spherical Alumina used as catalyst and its carrier Because there are a large number of unsaturated chemical bonds and catalytic active centers on the surface of alumina, it shows high chemical activity. Moreover, spherical alumina has the advantages of low particle wear, long service life and large specific surface area. Therefore, the performance of the catalyst and catalyst carrier made of spherical alumina can not be replaced by other materials.
Spherical alumina used in 3D printing Spherical alumina is the most commonly used material for 3D printing because of its high strength, high spheroidization and high temperature resistance. Because spherical alumina powder has good particle fluidity, chemical reaction rate and stacking property, it has the advantages of high solid content, good fluidity, easy cleaning and high mechanical properties as printing slurry.
