I-Scandium oxide, kunye nefomula yemichizaSc2O3, sisiqina esimhlophe esinyibilika emanzini kunye neasidi eshushu. Ngenxa yobunzima bokukhupha ngokuthe ngqo iimveliso ze-scandium kwi-scandium equlethe iiminerali, i-scandium oxide okwangoku ifunyenwe kwaye ikhutshwe kwiimveliso ze-scandium eziqulethe izimbiwa ezifana nentsalela yenkunkuma, amanzi amdaka, umsi kunye nodaka olubomvu.
Iimveliso zobuchule
Scandiumyimveliso ebalulekileyo yeqhinga. Ngaphambili, iSebe lezangaphakathi lase-US lipapashe uluhlu lweeminerali zeqhinga ze-35 (iiminerali ezibalulekileyo) ezibhekwa njengento ebalulekileyo kuqoqosho lwase-US kunye nokhuseleko lwesizwe (Uluhlu lokugqibela lweMinerals ebalulekileyo ye-2018). Phantse zonke izimbiwa zoqoqosho zibandakanyiwe, ezifana ne-aluminium esetyenziswa kumashishini, isinyithi seqela leplatinam ezisetyenziselwa ukuveliswa kwe-catalyst, izinto ezinqabileyo zomhlaba ezisetyenziselwa iimveliso ze-elektroniki, i-tin kunye ne-titanium esetyenziselwa ukuveliswa kwe-alloy, njl.
Ukusetyenziswa kweScandium oxide
I-scandium enye isetyenziswa ngokubanzi kwi-alloys, kwaye i-scandium oxide nayo idlala indima ebalulekileyo kwizinto ze-ceramic. Ngokomzekelo, izixhobo ze-tetragonal zirconia ze-ceramic ezinokuthi zisetyenziswe njengezinto ze-electrode kwiiseli ze-oxid eziqinileyo zinepropati ekhethekileyo. I-conductivity yale electrolyte iyanda ngokunyuka kweqondo lokushisa kunye ne-oxygen concentration kwindawo. Nangona kunjalo, i-crystal structure yale nto ye-ceramic ngokwayo ayinakho ukuhlala ngokuzinzileyo kwaye ayinayo ixabiso lezoshishino; kufuneka ifakwe ezinye izinto ezinokulungisa esi sakhiwo ukuze kugcinwe iimpawu zokuqala. Ukongeza i-6-10% ye-scandium oxide ifana nesakhiwo sekhonkrithi, evumela ukuba i-scandium oxide izinze kwi-lattice yesikwere.
I-Scandium oxide inokusetyenziswa njenge-densifier kunye ne-stabilizer yamandla aphezulu, i-high-resistant-resistant engineering engineering material ceramic silicon nitride. Inokuvelisa i-refractory phase Sc2Si2O7 kumda wamasuntswana amahle, ngaloo ndlela inciphisa i-deformation ephezulu yobushushu be-ceramics zobunjineli. Xa kuthelekiswa nokongeza ezinye ii-oxides, inokuphucula ngcono i-high-temperature mechanical propertiesi-silicon nitride. Ukongeza inani elincinci le-Sc2O3 kwi-UO2 kwi-reactor ephezulu yobushushu be-reactor fuel yenyukliya inokuphepha ukuguqulwa kwe-lattice, ukunyuka kwevolumu kunye nokuqhekeka okubangelwa ukuguqulwa kwe-UO2 ukuya kwi-U3O8.
I-Scandium oxide ingasetyenziswa njengento ephuphumayo yokwaleka kwe-semiconductor. I-Scandium oxide ingasetyenziselwa ukwenza i-laser-state solid-state lasers, i-high-definition high-definition electron guns, izibane ze-metal halide, njl.
Uhlalutyo lweshishini
Kwiminyaka yakutshanje, i-scandium oxide iye yatsala ingqalelo ngakumbi nangakumbi kwintsimi yeeseli zasekhaya ze-oksidi eziqinileyo (SOFC) kunye nezibane ze-halogen zesodium ye-scandium. I-SOFC ineengenelo zokuvelisa amandla aphezulu, ukusebenza kakuhle kokuhlanganiswa, ukugcinwa kobutyebi bamanzi, ukukhuselwa kokusingqongileyo okuluhlaza, ukudityaniswa kwemodyuli elula, kunye noluhlu olubanzi lokukhetha amafutha. Inexabiso elikhulu lesicelo kwiinkalo zokuvelisa amandla asasazwayo, iibhetri zamandla emoto, iibhetri zokugcina amandla, njl.
