Scandiumyinto enqabileyo nexabisekileyo efumene ingqalelo enkulu kwiminyaka yakutshanje ngenxa yeempawu zayo ezahlukeneyo eziluncedo. Iyaziwa ngokukhaphukhaphu kwayo kunye neempawu zayo zokuqina okuphezulu, iyenza ibe yinto efunwayo kumashishini afana ne-aerospace, i-elektroniki kunye namandla avuselelekayo. Nangona kunjalo, ngenxascandiumUkunqongophala kunye neendleko eziphezulu, ukutsalwa kwayo kunye nenkqubo yokucoca inokuba ngumngeni. Enye indlela ethe yaphononongwa kukuguqulaiscandium oxidekwiintsimbi yescandium. Kodwa unakoiscandium oxidezisulungekiswe ngempumelelo zibeintsimbi yescandium?
I-Scandium oxideyeyona ndlela ixhaphakileyo yescandiumefumaneka kwindalo. Ngumgubo omhlophe odla ngokuveliswa njengemveliso ekusetyenzweni kweentsimbi ezifana neuranium, itin kunye netungsten. Ngelixaiscandium oxidengokwayo inezinye izicelo kushishino lweseramikhi, amandla ayo okwenene alele kubuchule bayo bokuguqulelwa ekubeniintsimbi yescandium.
Inkqubo yokucoca iqala ngokuveliswa kweiscandium oxidekwaye ibandakanya amanyathelo amaninzi. Okokuqala, i-ore ene-scandium ikhutshwa emhlabeni kwaye iqhubela phambili kwiinkqubo zokuxhamla ukwahlula izinto ezixabisekileyo kwizinto ezingcolileyo. Ugxininiso olubangelwayo luphinde luqhutywe ngakumbi ukuvelisa ukucoceka okuphezuluiscandium oxideumgubo.
Kanye iiscandium oxideifunyenwe, inyathelo elilandelayo kukuguqula ibeintsimbi yescandium. Olu tshintsho luphunyezwa ngenkqubo ebizwa ngokuba kukuncitshiswa. Iindlela ezahlukeneyo zokunciphisa ziye zaphandwa, kodwa eyona ndlela ixhaphakileyo ibandakanya ukusetyenziswa kwesinyithi se-calcium njenge-agent yokunciphisa.I-Scandium oxideixutywe nekhalsiyam kwaye emva koko ifudunyezwe kumaqondo obushushu aphezulu kwivacuum okanye kwiatmosfera engasebenziyo. Oku kubangela ukuba i-calcium isebenze kunye neoksijini engaphakathiiscandium oxide, okubangelwa ukubunjwa kwe-calcium oxide kunyeintsimbi yescandium.
Nangona kunjalo, ukulungiswaiscandium oxidekwintsimbi ye-scandium ayikho inkqubo elula. Ukuqinisekisa inguqu eyimpumelelo, kukho imingeni ekufuneka yoyiswe. Obunye ubunzima obuphambili bukwi-reactivity ephezulu ye-scandium.Scandiumisabela ngokulula ngeoksijini, initrogen kunye nokufuma okusemoyeni, nto leyo eyenza ukuba ichaphazeleke lula kwi-oxidation kunye nongcoliseko. Ngoko ke, inkqubo yokunciphisa kufuneka ilawulwe ngokucophelela ukukhusela ukuphendula okungafunekiyo kunye nokugcina ubunyulu besiphumo se-scandium metal.
Omnye umceli mngeni ziindleko eziphezulu zokuvelisaiscandium yesinyithi. Ngokubascandiuminqabile ngokwendalo, ukutsalwa kwayo kunye nokusulungekiswa kufuna iteknoloji ephezulu kunye nezixhobo ezikhethekileyo, okukhokelela kwiindleko eziphezulu zemveliso. Ukwengeza,scandiumimfuno ihlala icolile, inyusa ngakumbiscandiumamaxabiso.
Ngaphandle kwale mingeni, siyaqhubeka ukwenza uphando kunye nomsebenzi wophuhliso ukuphucula ukusebenza kakuhle kunye nokuphumelela kweendlekointsimbi yescandiumimveliso. Ezi nzame zijolise ekwenzeni lula inkqubo yokusulungekiswa kunye nokuphuhlisa iindlela ezizinzileyo nezinoqoqosho zokutsala kunye nokucokisa i-scandium.
Isishwankathelo,iscandium oxideingaphuculwa ibeintsimbi yescandiumngenkqubo yokunciphisa.Nangona kunjalo, olu tshintsho alunangxaki ngenxascandium's reactivity kunye neendleko eziphezulu zemveliso ezinxulumene nokutsalwa kunye nokucokisa. Njengoko itekhnoloji ihambela phambili kwaye ifunascandiumukwanda, iinkqubo zokusulungekisa kwixesha elizayo zinokusebenza ngakumbi kwaye zingabizi kakhulu, ukwenzaintsimbi yescandiumimathiriyeli efikelelekayo nesetyenziswa ngokubanzi kuwo wonke amashishini.
