Spherical Alumina Powder (Mixed) Description

Formulated by combining powders from the SSAC Series, Spherical Alumina Powder (Mixed) is designed to elevate thermal conductivity performance. It boasts a notable spheroidization rate, optimal filling ratio, and outstanding thermal conductivity. The practice of employing a mixed composition with varied particle sizes, as seen in this formulation, enhances thermal conductivity efficiency by minimizing inter-particle gaps, optimizing phonon conduction channels, and thereby improving heat transfer.
