O le alumina sili ona lelei ose mea taua tele mo sima aoga.Pa'u alumina sili xz-L20, lapopo'a 100 nm, lanu pa'epa'e, 99% o mea mautu.E mafai ona faʻaopoopoina i Various resins faʻavae vai, i totonu o suauʻu faʻavae resins, solvents ma paʻu i se faʻaopoopoga tulaga o le 3% -5%, lea e mafai ona faʻaleleia atili le maaa o mea e oʻo atu i le 6-8H pe sili atu foi.
O le Saito Q-A1203, faʻatasi ai ma le maualalo o le vailaʻau ma le maualuga o le vevela, e leʻo se alumina faʻamamago, ma e leai se gaioiga faʻamalosi.O loʻo i ai le malosi o le vevela, faʻalelei lelei, tulaga tioata mautu, maualuga maʻaʻa ma lelei tulaga mautu, ma e mafai ona faʻaaogaina lautele i le faʻamalosia ma le faʻamalosi o palasitika eseese, paʻu, ceramics, mea faʻafefe ma isi oloa, aemaise lava le faʻaleleia o le mafiafia, mae'a, vevela ma malulu vaivai, gau gau, fetolofi tetee o ceramics ma le ofuina o mea polymer.
