Vaega:
Nano-silic particles e tusa ai ma lo latou fausaga ua vaevaeina i ni ituaiga se lua: P-ituaiga (Porous particles ) ma S-ituaiga (Spherical particles). P-ituaiga nano-silic surface o loʻo i ai se numera o nano-porous ma le fua o le pore o le 0.611ml / g; o lea, P-ituaiga e sili atu le tele o SSA faʻatusatusa i S-ituaiga (Vaai US3440). US3436 o le S-ituaiga ma lona SSA e ~ 170-200m2/g. E le gata i lea, o le P-ituaiga ultraviolet reflectivity o le> 85%, S-ituaiga:> 75%.
