    Scandium(III) Oxide tabi scandia jẹ agbo aibikita pẹlu agbekalẹ Sc2O3. Hihan jẹ itanran funfun lulú ti onigun eto. O ni awọn ọrọ oriṣiriṣi bi scandium trioxide, scandium(III) oxide ati scandium sesquioxide. Awọn ohun-ini physico-kemikali rẹ sunmo pupọ si awọn oxides aiye toje bi La2O3, Y2O3 ati Lu2O3. O jẹ ọkan ninu ọpọlọpọ awọn oxides ti awọn eroja aiye toje pẹlu aaye yo to gaju. Da lori imọ-ẹrọ lọwọlọwọ, Sc2O3/TREO le jẹ 99.999% ni giga julọ. O ti wa ni tiotuka ninu gbona acid, sibẹsibẹ insoluble ninu omi.
