I-Scandium(III) I-Oxide okanye i-scandia yikhompawundi ye-inorganic kunye ne-formula Sc2O3. Imbonakalo yimpuphu emhlophe ecocekileyo yecubic system. Inamabinzana ahlukeneyo afana ne-scandium trioxide, i-scandium(III) oxide kunye ne-scandium sesquioxide. Iimpawu zayo ze-physico-chemicals zisondele kakhulu kwezinye ii-oxides zomhlaba ezinqabileyo ezifana ne-La2O3, Y2O3 kunye ne-Lu2O3. Yenye yeeoksidi ezininzi zezinto ezinqabileyo zomhlaba ezinendawo ephezulu yokunyibilika. Ngokusekwe kubuchwephesha bangoku, iSc2O3/TREO inokuba ngama-99.999% phezulu. Iyanyibilika kwiasidi eshushu, nangona kunjalo ayinyibiliki emanzini.
