Nta:
Nano-silica hais raws li lawv cov qauv tau muab faib ua ob hom: P-hom (Porous hais) thiab S-hom (Spherical hais). P-hom nano-silica nto muaj ib tug xov tooj ntawm nano-porous nrog lub pore tus nqi ntawm 0.611ml / g; yog li ntawd, P-type muaj SSA loj dua piv rau S-hom (Saib US3440). US3436 yog S-hom thiab nws SSA yog ~ 170-200m2 / g. Ntxiv mus, P-hom ultraviolet reflectivity yog> 85%, S-hom:> 75%.
