Spherical Aluminium Oxide Powder (Conventional Type) Description
Spherical Aluminium Oxide Powder (Conventional Type) is produced using a high‐temperature melt process with a ball‐jet technique. The powder is then processed by sieving, cleaning and additional procedures to reach its final state. It achieves a high spheronisation rate, high packing density and high thermal conductivity. Due to its measured physical and chemical properties, the spherical aluminium oxide powder is used as a filler in thermal interface materials, heat‐resistant thermoplastics and aluminium-based copper‐clad laminates, among other applications.
