Product List / Alumina
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.
