High-purity fused spherical silica "EXCELICA"
EXCELICA is high-purity fused synthetic spherical silica produced by vapor phase reaction. The particle diameter ranges from the several level to 100 microns. Coarse grain cut grades are also available to suit various applications.

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.
