Scandium oxide (Sc2O3) yog ib qho tseem ceeb tshaj plaws ntawm cov khoom lag luam scandium. Nws cov khoom physicochemical zoo ib yam li cov tsis tshua muaj hauv ntiaj teb oxides (xws li La2O3, Y2O3 thiab Lu2O3), yog li cov txheej txheem tsim khoom siv hauv kev tsim khoom zoo sib xws. Sc2O3 tuaj yeem tsim cov khoom siv scandium (Sc), cov ntsev sib txawv (ScCl3, ScF3, ScI3, Sc2 (C2O4) 3, thiab lwm yam) thiab ntau yam scandium alloys (Al Sc, Al Zr Sc series). Cov khoom lag luam scandium no muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo rau kev lag luam. Vim tias Sc2O3 muaj qee tus yam ntxwv, nws muaj cov ntawv thov zoo hauv aluminium alloys, hluav taws xob lub teeb qhov chaw, lasers, catalysts, activators, ceramics, aerospace thiab lwm yam kev lag luam, thiab nws txoj kev vam meej yog dav heev.
Nyob rau xyoo 1970, Tuam Tshoj pib tsim cov khoom lag luam Sc2O3, thiab cov khoom hnyav hnyav nkag mus rau hauv khw. Nyob rau xyoo 1980, kev tsim khoom ntawm Sc2O3 hauv Suav teb tau nce mus txog qhov kawg, nrog cov khoom tsim tawm ntau dua 100 kg, feem ntau xa tawm mus rau Nyiv thiab Tebchaws Meskas. Txij li thaum xyoo 1990, Russia tau tsim cov khoom lag luam Sc2O3 ntau thiab muab tso rau hauv kev lag luam thoob ntiaj teb ntawm tus nqi qis, uas tau cuam tshuam loj heev rau kev tsim cov khoom lag luam scandium oxide hauv Suav teb, ua rau kev tsim cov Sc2O3 ntawm qis qis. Ntau cov kab ntau lawm tau raug tshem tawm, ua rau Tuam Tshoj lub peev xwm ntau lawm thiab cov khoom lag luam poob qis. Txawm li cas los xij, nyob rau xyoo tas los no, kev txhim kho ntawm Sc Al alloy thiab cov khoom siv hluav taws xob hluav taws xob hauv Suav teb tau txhawb kev tsim cov khoom lag luam ntawm Sc2O3. Tuam Tshoj yog nplua nuj nyob rau hauv scandium peev txheej. Nws tau tshaj tawm tias tam sim no, kev lag luam khaws cia ntawm scandium hauv ntiaj teb yog kwv yees li 2 lab tons, thaum nyob hauv Suav teb muaj txog 600000 txog 650000 tons, suav txog li 30 feem pua ntawm lub ntiaj teb tag nrho.
