Scandium Oxide
Scandium (III) Oxide los yog scandia yog ib qho inorganic compound nrog cov mis Sc2O3. Nws zoo li hmoov dawb zoo ntawm lub cubic system. Nws muaj ntau yam kev qhia xws li scandium trioxide, scandium (III) oxide thiab scandium sesquioxide. Nws cov khoom physico-chemical zoo ib yam li lwm cov oxides av tsawg xws li La2O3, Y2O3 thiab Lu2O3. Nws yog ib qho ntawm ntau cov oxides ntawm cov khoom av tsawg nrog lub melting point siab. Raws li cov thev naus laus zis tam sim no, Sc2O3 / TREO tuaj yeem yog 99.999% ntawm qhov siab tshaj plaws. Nws yaj tau hauv cov kua qaub kub, tab sis tsis yaj hauv dej.
