Mea Maualuga e le Mamafa i le Tulaga Lelei o le Alumina Grits Pa'epa'e ma le Fa'ata'ita'iga e leai se Totogi
Alumina pa'epa'e ua fa'afefiloi / Corundum pa'epa'eLototeleo se mea e tete'e atu i le vevela maualuga, lea e faia mai le pauta alumina maualuga le tulaga e ala i le fa'a'asuaina i luga atu o le 2000 ℃ i totonu o le ogaumu eletise ma fa'amālūlūina, ma vaevaeina i ni lapopo'a eseese o fatu. O le alumina pa'epa'e ua fa'afefiloi o le mea autu lea mo le gaosiga o mea e tete'e atu i le vevela e le'i fa'atulagaina ma foliga.
O le alumina paʻepaʻe ua faʻafefiloi e faia i le pauta alumina maualalo-sodium e maualuga le mama e ala i le faʻasusuina i le vevela maualuga, faʻamālūlūina ma faʻamaluluina, ona tuʻimomomoina lea. O le oneone alumina paʻepaʻe ua faʻafefiloi o loʻo i lalo o le faʻatonutonuina ma le faʻaeteete ina ia tausia le tufatufaina o le tele o fatu ma le foliga tutusa.
E masani ona faʻaaogaina i mea e faʻapala ai ladle, mea e faʻaaogaina ai uʻamea, mea e faʻafefiloi ai fana e le mafai ona uʻamea ma isi oloa e le mafai ona uʻamea; Mo mea e le mafai ona uʻamea e foliga i ai, e masani ona faʻaaogaina i mea mata e sili ona lelei o piliki corundum, corundum mullite, piliki porous plug e faʻaleleia ai le uʻamea, fana faʻasusu, faia o uʻamea ma le alamanuia faifai pea o le faʻapala.
E mafai fo'i ona fa'aaogaina e fai ma mea e fa'apulusaina ai, fa'apala sa'o, fa'asusu ma ufiufi, fa'apitoa o keramika

Fa'amanuiaga
0-1mm Alumina pa'epa'e e le mafai ona tetee atu i le vevela
1. Maualuga le ma'a'a ma mafiafia vaega. E lelei le lapotopoto o vaega ta'itasi.
2. O le lanu e paʻepaʻe mama, e leai ni mea leaga, ina ia mautinoa le lanu ma le manino o le pepa e teteʻe atu i le ofuina pe teteʻe atu i le ofuina.
3. Tufatufa tutusa o le tele o le vaega, tutusa le foliga o le vaega e tasi, ma sina vaega itiiti o le tete'e i le ofuina.
4. Mautu fa'akemikolo ma le 'āseta, leai se gaioiga a le alkali, mautu i le vevela maualuga e matua lelei lava.
1. Fa'apalapala oneone, fa'apulusaina ma oloina o u'amea ma tioata.
