Special characteristics
- High purity: EXCELICA™ is produced in a closed system using highly purified materials, resulting in silica with a trace of impurities such as radioelements, heavy metal elements, or ionic elements. Especially the amount of uranium or thorium contained, which emits alpha rays causing semiconductor memory malfunctions, in EXCELICA™ is less than 0.1ppb.
- Amorphous: The X-ray diffraction pattern shows that EXCELICA™ is amorphous.
