Scandium oxide
Scandium (III) Oxide lossis Scandia yog qhov sib xyaw ua ke nrog cov ntawv Sc2o3. Cov tsos yog zoo dawb hmoov ntawm cubic system. Nws muaj cov lus qhia sib txawv xws li scandium trioxide, scandium (iii) oxide thiab scandium soquoxide. Nws cov khoom siv tshuaj physico-tshuaj lom yog heev ze rau lwm lub ntiaj teb tsis tshua muaj txiaj ntsig zoo li La2O3, Y2O3 thiab Lu2O3. Nws yog ib qho ntawm ntau cov oxides ntawm lub ntiaj teb tsis tshua muaj zoo nrog lub siab melting point. Raws li kev siv thev naus laus zis, Sc2o3 / Treo yuav 99.999% ntawm siab tshaj plaws. Nws yog soluble nyob rau hauv kub acid, txawm li cas los insoluble hauv dej.
