I-Scandiumiyisici esiyivelakancane nesibalulekile esiye sathola ukunakwa okukhulu eminyakeni yamuva ngenxa yezakhiwo zayo ezihlukahlukene ezinenzuzo. Yaziwa ngezakhiwo zayo ezingasindi futhi ezinamandla aphezulu, okuyenza ibe yinto efunwa kakhulu ezimbonini ezifana ne-aerospace, electronics namandla avuselelekayo. Nokho, ngenxascandiumukushoda kanye nezindleko eziphezulu, ukukhishwa kwayo kanye nenqubo yokucwengisiswa kungaba yinselele. Enye indlela ehloliwe ukuguqulai-scandium oxidephakathiscandium metal. Kodwa kungabai-scandium oxidesicwengisiswe ngempumelelo sibescandium metal?
I-Scandium oxideiwuhlobo oluvame kakhulu lwescandiumetholakala emvelweni. Kuyimpushana emhlophe evamise ukukhiqizwa njengomkhiqizo ekucutshungulweni kwensimbi efana ne-uranium, ithini ne-tungsten. Ngenkathii-scandium oxideyona ngokwayo inezinye izinhlelo zokusebenza embonini ye-ceramics, amandla ayo angempela asemandleni ayo okuguqulelwa kuwoscandium metal.
Inqubo yokucwenga iqala ngokukhiqizwa kwei-scandium oxidefuthi kuhilela izinyathelo ezimbalwa. Okokuqala, insimbi equkethe i-scandium ikhishwa phansi futhi idlule uchungechunge lwezinqubo zokuzuza ukuze kuhlukaniswe izakhi ezibalulekile nokungcola. I-concentrate ewumphumela bese icutshungulwa ngokuqhubekayo ukuze ikhiqize ukuhlanzeka okuphezului-scandium oxideimpushana.
Once thei-scandium oxideitholakala, isinyathelo esilandelayo ukuyiguqulelascandium metal. Lolu shintsho lufezwa ngenqubo ebizwa ngokuthi ukunciphisa. Kuye kwaphenywa izindlela ezihlukahlukene zokunciphisa, kodwa indlela evamile kakhulu ihilela ukusetshenziswa kwensimbi ye-calcium njenge-ejenti yokunciphisa.I-Scandium oxideixutshwa ne-calcium bese ishiselwa emazingeni okushisa aphezulu endaweni engenalutho noma endaweni engenalutho. Lokhu kubangela ukuthi i-calcium isabele nge-oxygen engaphakathii-scandium oxide, okuholela ekwakhekeni kwe-calcium oxide kanyescandium metal.
Nokho, ukucwengai-scandium oxideku-scandium metal akuyona inqubo elula. Ukuqinisekisa uguquko oluyimpumelelo, kunezinselelo ezithile okudingeka zinqotshwe. Obunye bobunzima obuyinhloko busekusebenzeni kabusha okuphezulu kwe-scandium.I-Scandiumisabela kalula nge-oxygen, i-nitrogen ngisho nomswakamo osemoyeni, okwenza kube lula ukungenwa yi-oxidation nokunukubezeka. Ngakho-ke, inqubo yokunciphisa idinga ukulawulwa ngokucophelela ukuze kuvinjelwe ukusabela okungafuneki futhi kugcinwe ukuhlanzeka kwensimbi ye-scandium ephumela.
Enye inselele izindleko eziphezulu zokukhiqizai-metal scandium. Ngobascandiumiyivelakancane ngokwemvelo, ukukhishwa kwayo nokucwengisiswa kwayo kudinga ubuchwepheshe obuphambili kanye nemishini ekhethekile, okuholela ezindlekweni zokukhiqiza eziphezulu. Ngaphezu kwalokho,scandiumisidingo sihlala sivilapha, siqhubekela phambiliscandiumamanani.
Naphezu kwalezi zinselele, siyaqhubeka nokwenza ucwaningo kanye nomsebenzi wokuthuthukisa ukuze sithuthukise ukusebenza kahle kanye nokuphumelela kwezindlekoscandium metalukukhiqiza. Le mizamo ihlose ukwenza lula inqubo yokucwenga kanye nokuthuthukisa izindlela ezisimeme nezinomnotho zokukhipha kanye nokucwengisiswa kwe-scandium.
Ngokufigqiwe,i-scandium oxideingacwengwa ibescandium metalngenqubo yokunciphisa.Nokho, lokhu kuguqulwa akunazo izinselele ngenxascandiumukusebenza kabusha kanye nezindleko zokukhiqiza eziphezulu ezihambisana nokukhipha nokucwengisiswa kwayo. Njengoba ubuchwepheshe buthuthuka futhi nesidingo sescandiumukwanda, izinqubo zokucwenga zesikhathi esizayo zingase zisebenze kahle futhi zingabizi kakhulu, zenzescandium metalinto efinyeleleka kakhudlwana futhi esetshenziswa kabanzi kuzo zonke izimboni.
