Thortveitite ore
Scandiumalikatundu wa otsika kachulukidwe wachibale (pafupifupi ofanana aluminiyamu) ndi mkulu kusungunuka mfundo. Scandium nitride (ScN) ili ndi malo osungunuka a 2900C komanso ma conductivity apamwamba, ndikupangitsa kuti igwiritsidwe ntchito kwambiri m'mafakitale a zamagetsi ndi wailesi. Scandium ndi imodzi mwazinthu zopangira ma nyukiliya. Scandium imatha kulimbikitsa phosphorescence ya ethane ndikuwonjezera kuwala kwa buluu wa magnesium oxide. Poyerekeza ndi nyali zamphamvu kwambiri za mercury, nyali za sodium za scandium zili ndi zabwino monga kuwala kwapamwamba komanso mtundu wowala bwino, zomwe zimawapangitsa kukhala oyenera kujambula makanema ndi kuyatsa kwa plaza. Scandium itha kugwiritsidwa ntchito ngati chowonjezera cha nickel chromium alloys mumakampani opanga zitsulo kuti apange ma aloyi osagwirizana ndi kutentha. Scandium ndi chinthu chofunikira chopangira mbale zodziwira zapansi pamadzi. Kutentha kwa scandium kumafikira 500C, komwe kungagwiritsidwe ntchito muukadaulo wamlengalenga. ScN itha kugwiritsidwa ntchito potsata ma radioactive pazifukwa zosiyanasiyana. Scandium nthawi zina imagwiritsidwa ntchito pamankhwala.
Scandium makamaka imachokera ku scandium vanadium mineral. Tongshi yapangidwa ngati zopangira scandium m'maiko ndi zigawo monga Norway, Madagascar, ndi Mozambique. Anthu aku America adakonzanso miyala ya aluminium phosphate ore.
Thortveitite ndi mchere wosowa mwachilengedwe wokhala ndi zinthu zochepa. Ku China, imapezeka makamaka ku wolframite, wolframite, wolframite ndi cassiterite concentrate. Wolframite ndi cassiterite zili ndi SC2O; Kufikira 0.4% ndi 0.2%. Pamitsempha ya quartz ndi greisen deposit yokhala ndi wolframite, zomwe zili mndandanda wa wolframite zimafunika kukhala 0.02% ~ 0.09% pamakampani. Kwa ma depositi a cassiterite sulfide, makampani amafuna kuti ma scandium a cassiterite akhale 0.02% ~ 0.04%
