Scandium muaj tus lej atomic 21 thiab tau sawv cev rau hauv lub sijhawm teem los ntawm lub cim 'Sc'.
Scandium yog muab rho tawm los ntawm ib qho ntawm Scandinavia cov zaub mov tsis tshua muaj. Thaum raug huab cua, nws tsim ib tug daj los yog pinkish cam khwb cia. Scandium muaj cov cuab yeej yooj yim tarnishing thiab hlawv thaum ignited. Nws tseem yuav yaj hauv cov kua qaub thiab ua rau cov roj hydrogen.
Scandium yog tsim los ntawm cua sov scandium fluoride (ScF3) nrog calcium hlau. Cov tshuaj tsis zoo no tuaj yeem pom hauv cov khoom siv hauv tsev xws li tsom iav, lub teeb txuag hluav taws xob, teeb fluorescent, thiab TV.
Scandium tau pom tias txo cov khoom tawg yooj yim hauv lub zog siab aluminium alloy vuam. Scandium tau dhau los ua neeg nyiam tshaj li qhov tsim nyog catalyzer rau polishing iav. Aluminium scandium alloys feem ntau yog siv hauv kev lag luam aerospace thiab cov khoom ua si (xws li baseball, tsheb kauj vab, thiab lwm yam)
Scandium muaj nyob rau hauv cov kab mob hauv qhov xwm txheej. Nws yog 50th feem ntau cov khoom nyob rau hauv lub ntiaj teb, thiab nws muaj peev xwm pom nyob rau hauv ib tug kab nyob rau hauv ntau tshaj 800 minerals. Tag nrho cov khoom txhua xyoo yuav tsuas yog 50 kg.
