Faʻaaogaina alumina e tele micro-auala, o lea la o le faʻapitoa vaega e lapoʻa. E mafai ona faʻaaogaina o adsorbent, desiccant, defluorinating agents ma catalyst carrier. O se ituaiga o suʻesuʻega vai desiccant ma le pou-molemal adsorbent, e tusa ai ma le adsorbed molemino polarization, o le faʻapipiʻi malosi e malosi mo le vai, oxide, acetic acid, alkali ma isi Activated alumina o maualuga malosi, maualalo abrasion, leai faʻaluluina i le vai, leai se faʻalauteleina, leai se pauta, leai se māvae.
