Ifomula yamakhemikhali yei-scandium oxide is I-Sc2O3, okuqinile okumhlophe okuncibilika emanzini ne-asidi eshisayo. Ngenxa yobunzima bokukhipha ngokuqondileimikhiqizo ye-scandiumkusuka ku-scandium equkethe amaminerali, i-scandium oxide okwamanje itholwa ngokuyinhloko futhi ikhishwe emikhiqizweni ye-scandium equkethe amaminerali afana nensalela yemfucuza, amanzi angcolile, intuthu, nodaka olubomvu.
I-Scandiumisici samakhemikhali esinophawu Sc kanye nenombolo ye-athomu engu-21. Into eyodwa iyinsimbi eguquguqukayo ethambile, esiliva-emhlophe, evame ukuxutshwai-gadolinium, i-erbium, njll., ngokukhiqizwa okuncane kakhulu, futhi okuqukethwe kuqweqwe lomhlaba cishe ku-0.0005%. I-Scandium iwumkhiqizo wamasu obalulekile. Amazwe athuthukile njenge-Europe ne-United States asethule isikhuthazo nokuhlelwa okufanele. Isibonelo, ohlwini lwamaminerali angu-35 abalulekile ashicilelwe yi-United States, i-scandium ifakwe ohlwini lwezinto ezingavuthiwe ezimbonini; "Imihlahlandlela Yeqoqo Lokuqala Lokuboniswa Kwesicelo Sezinto Ezintsha Ezibalulekile (Ushicilelo luka-2018)" ekhishwe uMnyango Wezimboni Nobuchwepheshe Bolwazi ihlanganisa izinto ezi-3 ezintsha ezihlanganisa i-scandium nemikhiqizo yayo.
I-Scandium oxide
Okwamanje,i-scandium oxideisetshenziswe kabanzi kuma-alloys, ama-fuel cell, izinto ze-cathode, izibani ze-halogen ze-scandium sodium, ama-catalysts, ama-activators kanye ne-ceramics. I-aluminium-scandium alloys eyenziwe nge-scandium ne-aluminium inezinzuzo zokuminyana okuphansi, amandla aphezulu, ubulukhuni obuphezulu, i-plasticity enhle, ukumelana nokugqwala kanye nokuzinza okuqinile okushisayo. Zisetshenziswa kahle ezingxenyeni zesakhiwo zemicibisholo, i-aerospace, izindiza, izimoto kanye nemikhumbi. Izibani ze-scandium-sodium halogen ezenziwe nge-scandium oxide zinezinzuzo zokukhanya okuphezulu, umbala omuhle wokukhanya, ukonga amandla, impilo ende kanye nekhono eliqinile lokuphula inkungu. Zonga ugesi ngo-80% ngaphezu kwamalambu e-incandescent kanye nogesi ongaphezu kwama-50% kunamalambu e-mercury. Impilo yesevisi ingamahora angu-5,000 kuya kwangu-25,000, afaneleka kakhulu izindawo zangaphandle. Ngokusho "kombiko we-2021-2026 China Scandium Oxide Industry In-depth Research and Development Prospects Forecast Report" okhishwe yi-Xinshijie Industry Research Center, i-scandium oxide iyabiza, ekhawulela ukusetshenziswa kwayo kwezinga elikhulu. Usayizi wemakethe yomhlaba wonke wamanje ulinganiselwa ku-400 million yuan.
I-SOFC
Solid oxide fuel cells (SOFCs) aqukethe uphethiloli ohlinzekwe ngaphandle kanye ne-oxidant, i-cathode, i-anode ne-electrolyte. Njengomthombo wamandla osebenzayo nohlanzekile, zaziwa njengebhethri eliluhlaza lekhulu lama-21. Ukuguqulwa kwamandla okusebenza kahle kwamaseli kaphethiloli ajwayelekile kungama-50-70%, kuyilapho ukusebenza kahle okuphelele kwama-SOFC kusetshenziswa isistimu yokushisa ehlangene namandla kungaba phezulu ku-80%. Angasetshenziswa njengeziteshi zikagesi ezingaguquki emikhakheni yomphakathi efana nokuphakelwa kukagesi okuphakathi nendawo enkulu, ukunikezwa kwamandla okusabalaliswa okuphakathi nendawo, kanye nokushisa okuhlanganisiwe kwasendlini kanye nokuphakelwa kukagesi. Ngaphezu kwalokho, angasetshenziswa futhi njengemithombo yamandla eselula njengemithombo yamandla omkhumbi kanye nemithombo yamandla emoto yokuthutha, futhi abe nethuba elibanzi lokufaka isicelo.
I-Scandium ezinzile i-cerium zirconium composite powder (ebizwa ngokuthi i-scandium zirconium powder) ingasetshenziswa njengento ye-electrolyte yamaseli e-solid oxide fuel (SOFC). Le nto okwamanje iwumsebenzi we-electrolyte onokuqhutshwa okuphezulu okubikiwe, futhi ukuqhuba kwayo kokuthi 780 ℃ kuqhathaniswa nalokho kwe-YSZ ku-1000 ℃. Lo mkhiqizo ungangena esikhundleni sezinto ze-yttria ezizinzile ze-zirconia, ezine-conductivity ephakeme nokuzinza kwesikhathi eside, okunganciphisa izinga lokushisa lokusebenza kwe-SOFC, kunciphise ukusetshenziswa kwamandla, futhi kuthuthukise ukusebenza kahle kokuguqulwa kwamandla.
