Fa'amatalaga o le Oloa

O le fausaga o le tioata tetragonal, samasama pe a vevela, samasama pogisa mumu pe a liusuavai, o le amphoteric compound. E fai si faigofie ona solo i le vai, e faigofie ona solo i acids ma bases malolosi, ma e fausia ai masima faalua. Density 5.49 ~ 6.02g/cm3. O le tulaga e liusuavai ai e 733 ℃. O le tulaga e pupuna ai e 1260 ℃. E amata le sublimation i le 450℃ ma e saunia e ala i le acid thermal decomposition sa'o. E fa'aaogaina mo le antisepsis ma le fa'ailoaina o siama i tui puipui.
