Ifomula yemichiza yeiscandium oxide is Sc2O3, isiqina esimhlophe esinyibilikayo emanzini kunye neasidi eshushu. Ngenxa yobunzima bokukhupha ngokuthe ngqoiimveliso scandiumkwi-scandium equlethe iiminerali, i-scandium oxide ngoku ikakhulu ifunyanwa kwaye itsalwa kwimveliso ye-scandium equlethe iiminerali ezifana nentsalela yenkunkuma, amanzi amdaka, umsi, kunye nodaka olubomvu.
Scandiumsisiqalelo sekhemikhali esinophawu Sc kunye nenombolo yeathomu engu-21. Into enye yintsimbi ethambileyo, emhlophe-emhlophe, ehlala ixutywagadolinium, ierbium, njl., kunye nemveliso encinci kakhulu, kunye nomxholo kwi-crust yomhlaba malunga ne-0.0005%. I-Scandium yimveliso ebalulekileyo yeqhinga. Amazwe aphuhlileyo anjengeYurophu neUnited States aye azisa ukhuthazo olufanelekileyo nohlengahlengiso. Ngokomzekelo, kuludwe lwezimbiwa ezingama-35 eziphambili ezipapashwe yi-United States, i-scandium idweliswe njengemveliso ekrwada yemizi-mveliso; "Izikhokelo zoMboniso weSicelo seBatch yokuQala yeZixhobo eziNtsha eziNtsha (uHlelo lwe-2018)" olukhutshwe nguMphathiswa wezoShishino kunye neTeknoloji yoLwazi lubandakanya izixhobo ezitsha ze-3 ezibandakanya i-scandium kunye neemveliso zayo.
I-Scandium oxide
Ngoku,iscandium oxideisetyenziswe ngokubanzi kwii-alloys, iiseli ze-fuel, izinto ze-cathode, izibane ze-halogen ze-sodium ye-scandium, i-catalysts, i-activators kunye ne-ceramics. I-aluminium-scandium alloys eyenziwe nge-scandium kunye ne-aluminium ineenzuzo zokuxinana okuphantsi, amandla aphezulu, ubunzima obuphezulu, iplastiki enhle, ukuxhathisa ukubola kunye nokuzinza okuqinileyo kwe-thermal. Zisetyenziswa kakuhle kwiindawo zesakhiwo semijukujelwa, i-aerospace, inqwelomoya, iimoto kunye neenqanawa. Izibane ze-halogen ze-scandium-sodium ezenziwe nge-scandium oxide zineengenelo zokuqaqamba okuphezulu, umbala wokukhanya olungileyo, ukonga amandla, ubomi obude kunye nobuchule obuqinileyo bokuqhekeza inkungu. Zonga i-80% yombane ngaphezulu kunezibane ze-incandescent kunye ne-50% yombane ngaphezulu kunezibane zemercury. Ubomi benkonzo yi-5,000 ukuya kwii-25,000 iiyure, ezifanelekileyo ngokukodwa kwiindawo zangaphandle. Ngokutsho kwe "2021-2026 China Scandium Oxide Industry Report In-Depture Research and Development Prospects Report" ekhutshwe yiXinshijie Industry Research Centre, i-scandium oxide iyabiza, ethintela ukusetyenziswa kwayo okukhulu. Ubungakanani bemarike yehlabathi ngoku bumalunga nezigidi ezingama-400 zeeyuan.
SOFC
I-solid oxide fuel cell (SOFCs) iqulethe amafutha abonelelwe ngaphandle kunye ne-oxidant, i-cathode, i-anode kunye ne-electrolyte. Njengomthombo wamandla osebenzayo nococekileyo, zaziwa njengebhetri eluhlaza yenkulungwane yama-21. Ukusebenza koguqulo lwamandla kwiiseli zamafutha ngokubanzi ngama-50-70%, ngelixa ukusebenza kakuhle okubanzi kwee-SOFCs kusetyenziswa ubushushu obudibeneyo kunye nenkqubo yamandla kunokufikelela kuma-80%. Zingasetyenziswa njengezikhululo zamandla ezisisigxina kumasimi oluntu afana nonikezelo lwamandla oluphakathi nendawo enkulu, unikezelo lwamandla oluphakathi, kunye nekhaya elincinci elidityanisiweyo lobushushu kunye nobonelelo lwamandla. Ukongeza, zinokusetyenziswa njengemithombo yamandla eshukumayo efana nemithombo yamandla enqanawa kunye nemithombo yamandla ezithuthi zothutho, kwaye ibe nethemba elibanzi lesicelo.
I-Scandium izinzile i-cerium zirconium powder composite (ebizwa ngokuba yi-scandium zirconium powder) ingasetyenziselwa njengento ye-electrolyte yeeseli eziqinileyo ze-oxide (SOFC). Esi sixhobo okwangoku sisixhobo se-electrolyte enesona sixhobo siphezulu esixelwayo, kwaye ukuqhuba kwayo kwi-780 ℃ kuthelekiseka naleyo ye-YSZ kwi-1000 ℃. Le mveliso inokutshintsha izinto ze-yttria ezizinzile ze-zirconia, kunye ne-conductivity ephezulu kunye nokuzinza kwexesha elide, elinokunciphisa ubushushu bokusebenza be-SOFC, ukunciphisa ukusetyenziswa kwamandla, kunye nokuphucula ukuguqulwa kwamandla.
