Alumina / Al2O3

High-purity synthesis spherical alumina

  • ● Two average particle sizes are available: 0.25 µm and 10 µm.
  • ● High purity, high sphericity, non-porous surface, and excellent dispersibility.
  • ● Different to molten alumina, this alumina contains fewer ionic impurities such as Na,
    so it can also be used for high-heat resistant or high-voltage resistant applications.
  • ● Alumina with higher purity than the AO-5 type can also be provided.
