Fa'amatalaga Puupuu

White Fused Alumina o se maualuga mama, minerale gaosia.

O lo'o gaosia e ala i le tu'ufa'atasiga o le Bayer Alumina e fa'atonuina le tulaga mama i totonu o se ogaumu arc eletise i le vevela e sili atu nai lo le 2000˚C soso'o ai ma le fa'agasologa fa'amausaliina.

O le fa'atonuina o le lelei o mea mata'utia ma fa'amaufa'ailoga fa'afefiloi e fa'amautinoa ai oloa e maualuga le mama ma maualuga le pa'epa'e.

E sili atu ona nutimomoia le pa'u mālūlū, fa'amama mai mea fa'amama maneta i fa'amama maneta maualuga ma fa'avasegaina i ni vaega ninii lapopo'a e fetaui ma le fa'aoga mulimuli.
