Ubunzima Ekukhuphukeni Kwezintengo Zomhlaba Ezingavamile ngenxa Yokwehliswa Kwezinga Lokusebenza Lamabhizinisi Abalulekile Kazibuthe
Isimo semakethe yomhlaba eyivelakancane ngoMeyi 17, 2023 Intengo iyonke yomhlaba ongavamile e-China ibonise ukuthambekela okukhuphukayo okukhuphukayo, okubonakaliswa ikakhulukazi ekwenyukeni okuncane kwamanani e-praseodymium neodymium oxide, i-gadolinium oxide, ne-dysprosium iron alloy ukuya kuma-yuan angama-465000/ ton, 272000 yuan/kuya...Funda kabanzi -
Ukwethulwa kwe-thortveitite ore
I-Thortveitite ore I-Scandium inezakhiwo zokuminyana okuphansi kwesihlobo (cishe ilingane ne-aluminium) kanye nephoyinti lokuncibilika eliphezulu. I-Scandium nitride (ScN) inephuzu lokuncibilika elingu-2900C kanye nokusebenza okuphezulu, okuyenza isetshenziswe kabanzi ezimbonini zikagesi nezemisakazo. I-Scandium ingenye yezinto ezisetshenziswa...Funda kabanzi -
Izindlela zokukhipha i-scandium
Izindlela zokukhipha i-scandium Isikhathi eside ngemva kokutholakala kwayo, ukusetshenziswa kwe-scandium akuzange kuboniswe ngenxa yobunzima bayo ekukhiqizeni. Ngokuthuthuka okwandayo kwezindlela zokuhlukanisa izinto ezingavamile zomhlaba, manje sekunohlelo oluvuthiwe lokugeleza kokuhlanza amaskandi...Funda kabanzi -
Ukusetshenziswa okuyinhloko kwe-scandium
Ukusetshenziswa okuyinhloko kwe-scandium Ukusetshenziswa kwe-scandium (njengento eyinhloko yokusebenza, hhayi i-doping) kugxilwe endaweni ekhanyayo kakhulu, futhi akuyona ihaba ukuyibiza ngokuthi iNdodana Yokukhanya. 1. Isibani sesodium ye-Scandium Isikhali sokuqala esiwumlingo se-scandium sibizwa nge-scandium sodium lamp, wc...Funda kabanzi -
Izakhi Zomhlaba Ezingavamile | I-Lutetium (Lu)
Ngo-1907, u-Welsbach no-G. Urban benza olwabo ucwaningo futhi bathola into entsha evela ku-"ytterbium" besebenzisa izindlela zokuhlukanisa ezihlukene. U-Welsbach waqamba lesi sici ngokuthi Cp (Cassiope ium), kuyilapho u-G. Urban wayiqamba ngokuthi Lu (Lutetium) esuselwe egameni elidala lika-Paris elithi lutece. Kamuva, kwatholakala ukuthi uCp kanye...Funda kabanzi -
Isici somhlaba esingavamile | I-Ytterbium (Yb)
Ngo-1878, u-Jean Charles kanye no-G.de Marignac bathola into entsha engavamile yomhlaba ku-"erbium", ebizwa ngokuthi i-Ytterbium ka-Ytterby. Ukusetshenziswa okuyinhloko kwe-ytterbium kungokulandelayo: (1) Isetshenziswa njengesivikelo esishisayo. I-Ytterbium ingathuthukisa kakhulu ukumelana nokugqwala kwe-zinc ene-electrodeposited ...Funda kabanzi -
Isici somhlaba esingavamile | I-Thulium (Tm)
I-Thulium element yatholwa nguCliff eSweden ngo-1879 futhi yaqanjwa ngokuthi i-Thulium ngegama elidala elithi Thule eScandinavia. Ukusetshenziswa okuyinhloko kwe-thulium kanje. (1) I-Thulium isetshenziswa njengomthombo wemisebe wezokwelapha okhanyayo nolula. Ngemuva kokucwiliswa ekilasini elisha lesibili ngemuva koku...Funda kabanzi -
Isici somhlaba esingavamile | I-erbium (Er)
Ngo-1843, i-Mossander yaseSweden yathola i-element erbium. Izakhiwo ezibonakalayo ze-erbium zigqame kakhulu, futhi ukukhanya okuphuma ku-1550mm kwe-EP+, obekulokhu kukhathaza njalo, kunokubaluleka okukhethekile ngoba lobu bude begagasi butholakala ngokunembile ekuphazamisekeni okuphansi kwe-optic...Funda kabanzi -
Isici somhlaba esingavamile | i-cerium (Ce)
I-elementi 'cerium' yatholwa futhi yaqanjwa ngo-1803 ngu-German Klaus, abaseSweden Usbzil, kanye no-Hessenger, kukhunjulwa i-asteroid Ceres eyatholwa ngo-1801. Ukusetshenziswa kwe-cerium kungafingqwa kakhulu kulezi zici ezilandelayo. (1) I-Cerium, njengesengezo sengilazi, ingamunca i-ultravio...Funda kabanzi -
