The chemical chilinganizo chascandium oxide is Chithunzi cha Sc2O3, cholimba choyera chomwe chimasungunuka m'madzi ndi asidi otentha. Chifukwa cha zovuta kuchotsa mwachindunjiscandium mankhwalakuchokera ku scandium yokhala ndi mchere, scandium oxide pakadali pano imapezedwanso ndikuchotsedwa muzinthu za scandium zomwe zimakhala ndi mchere monga zotsalira za zinyalala, madzi oyipa, utsi, ndi matope ofiira.
Scandiumndi chinthu chamankhwala chokhala ndi chizindikiro Sc ndi nambala ya atomiki 21. Chinthu chimodzi ndi chitsulo chofewa, choyera chasiliva, chomwe nthawi zambiri chimasakanizidwa ndigadolinium, erbium, etc., ndi kupanga kochepa kwambiri, ndipo zomwe zili pansi pa nthaka zimakhala pafupifupi 0.0005%. Scandium ndi chinthu chofunikira kwambiri. Mayiko otukuka monga Europe ndi United States ayambitsa kulimbikitsana koyenera ndi kusanja. Mwachitsanzo, pamndandanda wa migodi 35 yofunika kwambiri yofalitsidwa ndi United States, scandium yalembedwa ngati zinthu zopangira mafakitale; "Malangizo a Gulu Loyamba la Kugwiritsa Ntchito Chiwonetsero cha Zida Zatsopano Zofunikira (Kusindikiza kwa 2018)" loperekedwa ndi Unduna wa Zamakampani ndi Ukadaulo Wachidziwitso umakhudzanso zida 3 zatsopano zophatikiza scandium ndi zinthu zake.
Scandium oxide
Pakadali pano,scandium oxidewakhala ankagwiritsa ntchito aloyi, maselo mafuta, cathode zipangizo, scandium sodium halogen nyali, chothandizira, activators ndi ziwiya zadothi. Aluminium-scandium alloys opangidwa ndi scandium ndi aluminiyamu ali ndi ubwino wocheperako, mphamvu zambiri, kuuma kwakukulu, pulasitiki yabwino, kukana kwa dzimbiri ndi kukhazikika kwamphamvu kwa kutentha. Amagwiritsidwa ntchito bwino pamapangidwe a zida zoponya, ndege, ndege, magalimoto ndi zombo. Nyali za scandium-sodium halogen zopangidwa kuchokera ku scandium oxide zili ndi ubwino wowala kwambiri, kuwala kwabwino, kupulumutsa mphamvu, moyo wautali komanso kuthyola chifunga champhamvu. Amapulumutsa magetsi ochulukirapo 80% kuposa nyali za incandescent ndi magetsi ochulukirapo 50% kuposa nyali za mercury. Moyo wautumiki ndi maola 5,000 mpaka 25,000, omwe ali oyenera makamaka kumalo akunja. Malinga ndi "2021-2026 China Scandium Oxide Industry Market In-Depth Research and Development Prospects Forecast Report" yotulutsidwa ndi Xinshijie Industry Research Center, scandium oxide ndiyokwera mtengo, yomwe imalepheretsa kugwiritsa ntchito kwake kwakukulu. Kukula kwa msika wapadziko lonse lapansi pano ndi pafupifupi ma yuan 400 miliyoni.
SOFC
Solid oxide fuel cell (SOFCs) imakhala ndi mafuta operekedwa kunja ndi okosijeni, cathode, anode ndi electrolyte. Monga gwero lamphamvu komanso loyera lamagetsi, amadziwika kuti batire yobiriwira yazaka za zana la 21. Mphamvu yosinthira mphamvu yama cell amafuta ambiri ndi 50-70%, pomwe mphamvu yathunthu ya ma SOFC ogwiritsa ntchito kutentha kophatikizana ndi mphamvu yamagetsi imatha kufika 80%. Atha kugwiritsidwa ntchito ngati malo opangira magetsi okhazikika m'magawo aboma monga magetsi akuluakulu apakati, magetsi apakatikati, ndi magetsi ang'onoang'ono kuphatikiza kutentha ndi magetsi. Kuphatikiza apo, atha kugwiritsidwanso ntchito ngati magwero amagetsi am'manja monga magwero amagetsi apamadzi ndi magwero amagetsi agalimoto, komanso kukhala ndi chiyembekezo chogwiritsa ntchito kwambiri.
Scandium okhazikika cerium zirconium composite ufa (wotchedwa scandium zirconium ufa) angagwiritsidwe ntchito ngati electrolyte chuma olimba okusayidi mafuta maselo (SOFC). Zinthuzi pakadali pano ndizopangidwa ndi ma electrolyte omwe ali ndi mbiri yabwino kwambiri, ndipo madulidwe ake pa 780 ℃ akufanana ndi a YSZ pa 1000 ℃. Izi zitha kulowa m'malo mwa zida zachikhalidwe za yttria zokhazikika za zirconia, zokhala ndi madulidwe apamwamba komanso kukhazikika kwanthawi yayitali, zomwe zimatha kuchepetsa kutentha kwa SOFC, kuchepetsa kugwiritsa ntchito mphamvu, komanso kusintha mphamvu zamagetsi.
