Qaabka kiimikada eescandium oxide is Sc2O3, adag cad oo ku milma biyaha iyo aashitada kulul. Sababtoo ah dhibka soo saarista tooska ahalaabta scandiumScandium oo ay ku jiraan macdan, scandium oxide ayaa inta badan laga soo saaraa lagana soo saaraa alaabada iskaandiyamka oo ay ku jiraan macdanta sida hadhaaga qashinka, biyaha wasakhda ah, qiiqa, iyo dhoobada cas.
Scandiumwaa curiye kiimiko ah oo leh calaamada Sc iyo lambarka atomiiga 21. Walaxda keli ahi waa bir kala-guur oo jilicsan, silvery-cad, oo inta badan lagu qaso.gadolinium, erbiumiwm, oo leh wax-soo-saar aad u yar, iyo waxa ku jira qolofka dhulku waa qiyaastii 0.0005%. Scandium waa badeecad istaraatiijiyadeed oo muhiim ah. Wadamada horumaray sida Yurub iyo Maraykanka ayaa soo bandhigay dhiirigelin iyo kala saarid la xidhiidha. Tusaale ahaan, liiska 35 macdanta muhiimka ah ee Maraykanku daabacay, scandium waxa loo taxaabay sida alaabta ceeriin ee warshadaha; "Hagaha Dufcadda Koowaad Bandhigga Qalabka Cusub ee Muhiimka ah (2018 Edition)" oo ay soo saartay Wasaaradda Warshadaha iyo Tignoolajiyada ayaa ku lug leh 3 qalab oo cusub oo ku lug leh scandium iyo alaabteeda.
Scandium oxide
Hadda,scandium oxideayaa si weyn loogu isticmaalay Alloys, unugyada shidaalka, qalabka cathode, scandium sodium halogen lamps, kicinta, activators iyo ceramics. Aluminium-scandium alloys oo ka samaysan scandium iyo aluminium waxay leeyihiin faa'iidooyinka cufnaanta hoose, xoogga sare, adkaanta sare, caaga wanaagsan, caabbinta daxalka iyo xasilloonida kulaylka xooggan. Waxaa si fiican loogu isticmaalaa qaybaha qaab dhismeedka gantaalada, hawada sare, duulista, baabuurta iyo maraakiibta. Scandium-sodium halogen nalalka laga sameeyay scandium oxide waxay leeyihiin faa'iidooyinka dhalaalka sare, midabka iftiinka wanaagsan, badbaadinta tamarta, cimri dheer iyo awooda jabinta ceeryaamo xoog leh. Waxay badbaadiyaan 80% koronto ka badan nalalka shidan iyo 50% koronto ka badan nalalka meerkuriga. Nolosha adeeggu waa 5,000 ilaa 25,000 saacadood, taasoo si gaar ah ugu habboon meelaha bannaanka ah. Sida laga soo xigtay "2021-2026 Shiinaha Scandium Oxide Warshadaha Suuqa Si qoto dheer Cilmi-baarista iyo Warbixinta Saadaasha Horumarka ee Horumarinta" oo ay sii daysay Xarunta Cilmi-baarista Warshadaha Xinshijie, scandium oxide waa qaali, taas oo xaddidaysa codsigeeda ballaaran. Baaxadda suuqa caalamiga ah ee hadda waa qiyaastii 400 milyan yuan.
SOFC
Unugyada shidaalka adag (SOFCs) waxay ka kooban yihiin shidaal dibadda laga keeno iyo oksidaant, cathode, anode iyo electrolyte. Sida ilo tamar hufan oo nadiif ah, waxaa loo yaqaan baytariga cagaaran ee qarniga 21aad. Waxtarka tamarta beddelka tamarta ee unugyada shidaalka guud waa 50-70%, halka waxtarka dhammaystiran ee SOFC-yada isticmaalaya nidaamka kulaylka iyo tamarta la isku daray ay noqon karto ilaa 80%. Waxaa loo isticmaali karaa sidii saldhigyo koronto oo go'an oo ku yaala goobaha madaniga ah sida sahay koronto oo ballaaran, koronto qaybsan oo dhexdhexaad ah, iyo kulaylka iyo korontada guriga oo isku jira. Intaa waxaa dheer, waxaa sidoo kale loo isticmaali karaa ilaha tamarta wareega sida ilaha tamarta markabka iyo ilaha tamarta gaadiidka, waxayna leeyihiin rajooyin codsi oo ballaaran.
Scandium xasiloon cerium zirconium budada isku dhafan (oo loo yaqaan 'scandium zirconium budada') waxaa loo isticmaali karaa walxo elektrolyte ah oo loogu talagalay unugyada shidaalka adag ee oksaydhka (SOFC). Maaddadan hadda waa maaddada elektrolytka ee ugu sarreeya ee la soo sheegay, iyo conductivity 780 ℃ waxay la mid tahay kan YSZ ee 1000 ℃. Alaabtani waxay bedeli kartaa agabka yttria ee xasiloon ee zirconia, oo leh firfircooni sare iyo xasilloonida muddada dheer, taas oo yarayn karta heerkulka shaqada ee SOFC, hoos u dhigi karta isticmaalka tamarta, iyo hagaajinta waxtarka beddelka tamarta.
