Izindlela zokukhipha zescandium
Isikhathi eside ngemuva kokutholakala kwayo, ukusetshenziswa kwe-scandium akuzange kuboniswe ngenxa yobunzima bayo ekukhiqizeni.Ngokuthuthuka okwandayo kwezindlela zokuhlukanisa izakhi zomhlaba ezingavamile, manje sekukhona ukugeleza kwenqubo evuthiwe yokuhlanza izinhlanganisela ze-scandium.Ngenxa yokuthi i-scandium ine-alkalinity ebuthakathaka kakhulu uma iqhathaniswa nezakhi ze-yttrium ne-lanthanide, ama-hydroxides aqukethe amaminerali axutshwe yi-elementi yomhlaba engavamile equkethe i-scandium.Ngemuva kokwelashwa, i-scandium hydroxide izoqala ukushona phansi lapho idluliselwa esixazululo futhi iphathwa nge-ammonia.Ngakho-ke, ukusetshenziswa kwendlela yemvula elinganiselwe kungayihlukanisa kalula nezinto ezingavamile zomhlaba.Enye indlela ukusebenzisa i-hierarchical decomposition of nitrate ukuze uhlukanise, njengoba i-nitric acid iyona elula kakhulu ukubola futhi ingafinyelela inhloso yokuhlukanisa i-scandium.Ukwengeza, ukululama okuphelele kwe-scandium ehambisana ne-uranium, i-tungsten, i-tin namanye ama-mineral deposits nakho kuwumthombo obalulekile we-scandium.
Ngemva kokuthola inhlanganisela ehlanzekile ye-scandium, iguqulwa ibe yi-ScCl3 futhi ihlanganiswe ne-KCI ne-LiCI.I-zinc encibilikisiwe isetshenziswa njenge-cathode ye-electrolysis, okwenza i-scandium igibele ku-zinc electrode.Khona-ke, i-zinc iyahwamuka ukuze kutholakale i-metallic scandium.Lena insimbi emhlophe eyisiliva ekhanyayo, futhi izakhiwo zayo zamakhemikhali nazo zisebenza kakhulu.Ingasabela ngamanzi ashisayo ukuze ikhiqize i-hydrogen.
Sikhandimuinezindawo zokuminyana okuhlobene okuphansi (cishe ilingane ne-aluminium) nendawo yokuncibilika ephezulu.I-Nitriding (SCN) inephuzu lokuncibilika elingu-2900 ℃ kanye nokuhanjiswa okuphezulu, okuyenza isetshenziswe kabanzi ezimbonini zikagesi nezomsakazo.I-Scandium ingenye yezinto zokwakha ama-thermonuclear reactors.I-Scandium ingashukumisa i-phosphorescence ye-ethane futhi ithuthukise ukukhanya okuluhlaza kwe-magnesium oxide.Uma kuqhathaniswa nezibani ze-mercury ezinengcindezi ephezulu, izibani ze-sodium ezibukhali zinezinzuzo ezifana nokusebenza kahle kokukhanya okuphezulu kanye nombala wokukhanya omuhle, okuwenza afanelekele ukuqoshwa kwefilimu nokukhanyisa kweplaza.
I-Scandium ingasetshenziswa njengesengezo se-nickel chromium alloys embonini ye-metallurgical ukukhiqiza ama-alloys aphikisana nokushisa okuphezulu.I-Scandium iwumthombo obalulekile wamapuleti okubona umkhumbi-ngwenya.Ukushisa okuvuthayo kwe-scandium kufinyelela ku-5000 ℃, okungasetshenziswa kubuchwepheshe bomkhathi.I-Sc ingasetshenziselwa ukulandelela imisebe ngezinjongo ezihlukahlukene.I-Scandium kwesinye isikhathi isetshenziswa kwezokwelapha.
