Nā hiʻohiʻona:
Hoʻokaʻawale ʻia nā ʻāpana Nano-silica e like me ko lākou ʻano: P-type (Porous particles) a me S-type (Spherical particles). P-type nano-silic surface he mau nano-porous me ka pore rate o 0.611ml /g; No laila, ʻoi aku ka nui o ka SSA P-type i ka hoʻohālikelike ʻana me ke ʻano S (E nānā i ka US3440). ʻO US3436 ka S-type a ʻo kāna SSA he ~170-200m2/g. Eia hou, P-type ultraviolet reflectivity he> 85% , S-type: >75%.
