Āhuatanga:
Ko nga matūriki Nano-silica e ai ki o raatau hanganga ka wehewehea ki nga momo e rua: P-momo (Porous particles ) me S-momo (Spherical matūriki). P-momo nano-silica mata he maha o te nano-porous me te tere pore o 0.611ml /g; no reira, he nui ake te SSA momo-P ki te whakataurite ki te momo-S (Tirohia te US3440). Ko te US3436 he momo-S me tana SSA he ~170-200m2/g. I tua atu, P-momo ultraviolet reflectivity he> 85% , S-momo:> 75%.

Nga Tikanga Whakamatau:
1. Te tikanga tuku irahiko moroiti (TEM), he iti te matūriki nano-silica, he iti te tohatoha matūriki.
2. Ko te tikanga BET, ko te matūriki nano-silica he nui te waahanga mata motuhake.
3. Ko te tikanga whakakitenga infrared, he matūriki nano-silica te maha o nga roopu hydroxyl me nga here toenga haunga kore i runga i te mata, ka hanga i te rereke mai i te ahua pumau o te hangahanga waikura silicon.
4. Cary-5E tikanga whakamātautau spectrophotometer, matūriki nano-silica--te whakaata teitei ki te ngaru roa me te marama e kitea ana mo te UV.
5. Omnisorp100CX rohe mata me te porosity tātaritanga, P-momo nano-silica mata kei roto i te maha o nano porous ki te tere pore o 0.611ml /g.
