Spherical Alumina Powder (Conventional Type) is manufactured through the high-temperature melting-sphere-jet method, followed by processes such as sieving and purification to obtain the final product. It demonstrates a notable spheroidization rate, a substantial filling ratio, and elevated thermal conductivity. Due to its distinctive and outstanding physicochemical properties, Spherical Alumina Powder has found extensive applications as a filler in thermal interface materials, thermal engineering plastics, aluminum-based Copper-Clad Laminates, and similar applications.
