    I-Scandium Oxide

    I-Scandium(III) I-Oxide okanye i-scandia yi-inorganic compound ene-formula ye-Sc2O3. Imbonakalo yayo yi-powder emhlophe ecolekileyo ye-cubic system. Ineempawu ezahlukeneyo ezifana ne-scandium trioxide, i-scandium(III) oxide kunye ne-scandium sesquioxide. Iipropati zayo ze-physico-chemical zisondelelene kakhulu nezinye ii-rare earth oxides ezifana ne-La2O3, i-Y2O3 kunye ne-Lu2O3. Yenye yee-oxides ezininzi zezinto ze-rare earth ezine-melting point ephezulu. Ngokusekelwe kubuchwepheshe bangoku, i-Sc2O3/TREO inokuba yi-99.999% ephezulu. Inyibilika kwi-asidi eshushu, nangona kunjalo ayinyibiliki emanzini.
