Spherical Alumina Powder (Conventional Type) Description
Spherical Alumina Powder (Conventional Type) is produced by the high-temperature melting-sphere-jet method, and then sieving, purification, and other processes to produce the final object. It exhibits a high spheroidization rate, high filling ratio, and high thermal conductivity. Because of its unique and excellent physicochemical properties, Spherical Alumina Powder has been widely used as the filler of thermal interface materials, thermal engineering plastics and aluminum-based Copper-Clad Laminates, and so on.
