We provide 9N (99.9999999%) high-purity, uniform-sized spherical silicon at the μm level. It can be used for solar cells, MEMS, etc. We can also provide high-purity 6N (99.9999%) spherical silicon spheres that are uniform in mm units at low cost. It is also suitable as a starting material for silicon ingot manufacturing and as a filter material in a high temperature environment.
