Spherical Alumina Powder (Narrow Particle Size Distribution) Description

Spherical Alumina Powder (Narrow Particle Size Distribution) is produced using the high-temperature melting-sphere-jet method, followed by processes such as sieving, purification, and additional treatments to achieve its final form. Exhibiting a high spheroidization rate, optimal filling ratio, excellent thermal conductivity, and a narrow particle size distribution, this powder leverages its unique physicochemical properties. It is extensively used in epoxy molding compounds, thermal interface materials, thermal plastics, and thermal clads.
