Silica / SiO2
High-purity synthesis spherical silica
- ● 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.
- ● Two levels of purity are available: SO-C type (regular) and SO-E type (low-alpha beam).
In particular, 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.
