1.Alamanuia Keramiki:O le paʻu alumina e faʻaaogaina lautele e avea o se mea mataʻutia mo le faia o sima, e aofia ai mea faʻaeletoroni faʻaeletoroni, faʻamaʻi faʻamalama, ma mea faʻapitoa faʻapitoa.
2.Alamanuia Faila ma Abrasive:O le pa'u alumina e fa'aaogaina e fai ma mea e fa'aiila ma fa'ama'i i fa'aoga 'ese'ese e pei o tioata fa'apipi'i, fa'ama'i semiconductor, ma u'amea.
3.Catalysis:O le paʻu alumina o loʻo faʻaaogaina e avea o se lagolago faʻamalosi i le pisinisi petrochemical e faʻaleleia ai le lelei o faʻamalosi faʻaaogaina i le faʻamamaina.
4.Fa'afuifu fa'avevela:O le paʻu alumina e faʻaaogaina e fai ma mea faʻapipiʻi e tuʻuina atu ai le pala ma le ofuina o le tetee i luga o le tele o mea i totonu o le vaalele ma fale taʻavale.
5.Insulation eletise:O le paʻu alumina e faʻaaogaina e avea o se mea faʻapipiʻi eletise i masini eletise ona o le maualuga o le malosi dielectric.
6.Alamanuia afi:O le paʻu alumina e faʻaaogaina e avea o se mea faʻafefete i faʻaoga maualuga-vevela, e pei o le ogaumu, ona o le maualuga o le liusuavai ma le faʻamautuina lelei o le vevela.
7.Fa'aopoopo i Polymers:E mafai ona faʻaaogaina le paʻu alumina e fai ma faʻaopoopoga i polymers e faʻaleleia ai a latou mea faʻainisinia ma vevela.
Afai ei ai ni au fesili.Faamolemole lagona le saoloto e faʻafesoʻotaʻi i matou.
