- Product Highlights
- Spherical particles characterized by sharp particle size distribution.
- Average particle size can be controlled from 0.2 to 2.0 µm as desired.
- High purity, fewer ionic impurities, non-porous surface, and excellent dispersibility.
- The SO-E type is the grade compatible with chips (e.g. memory chips).
- High-purity products use the low-alpha beam grade, specialized for chips, such as memory. As regular products do not contain ionic impurities, they can be used for electronic devices.
