Imeko yemarike yomhlaba enqabileyo nge-17 kaMeyi ka-2023 Ixabiso lilonke lehlabathi elinqabileyo e-China libonise ukuguquguquka okunyukayo, okubonakaliswa ikakhulu kunyuso oluncinci lwamaxabiso epraseodymium neodymium oxide, igadolinium oxide, kunye ne-dysprosium iron alloy ukuya kuma-465000 yuan/ itoni, 272000 yuan/uku...Funda ngokugqithisileyo -
Ukuqaliswa kwentsimbi ye-thortveitite
I-Thortveitite ore I-Scandium ineempawu zokuxinana kwezihlobo eziphantsi (phantse zilingane ne-aluminium) kunye neqondo eliphezulu lokunyibilika. I-Scandium nitride (ScN) ine-melting point ye-2900C kunye ne-conductivity ephezulu, eyenza isetyenziswe ngokubanzi kumashishini e-electronics kunye nerediyo. I-Scandium yenye yezinto ze...Funda ngokugqithisileyo -
Iindlela zokukhupha i-scandium
Iindlela zokukhutshwa kwe-scandium Ixesha elide emva kokufunyanwa kwayo, ukusetyenziswa kwe-scandium akuzange kuboniswe ngenxa yobunzima bayo kwimveliso. Ngokuphucuka okwandayo kweendlela ezinqabileyo zokwahlula izinto zomhlaba, ngoku kukho inkqubo evuthiweyo yokuhamba yokucoca i-scandi ...Funda ngokugqithisileyo -
Ukusetyenziswa okuphambili kwe-scandium
Ukusetyenziswa okuphambili kwe-scandium Ukusetyenziswa kwe-scandium (njengeyona nto isebenzayo, kungekhona i-doping) igxininiswe kwindlela eqaqambileyo kakhulu, kwaye akusiyo ukugqithisa ukuyibiza ngokuthi nguNyana wokukhanya. 1. Isibane sesodium yeScandium Isixhobo sokuqala somlingo se-scandium sibizwa ngokuba sisibane sesodium ye-scandium, i-whic...Funda ngokugqithisileyo -
Izinto ezinqabileyo zomhlaba | ILutetium (Lu)
Kwi-1907, u-Welsbach kunye noG. Urban baqhube uphando lwabo kwaye bafumanisa into entsha kwi "ytterbium" besebenzisa iindlela ezahlukeneyo zokuhlukana. U-Welsbach wathiya le elementi Cp (Cassiope ium), ngelixa uG. Urban wayibiza ngokuba yiLu (Lutetium) ngokusekelwe kwigama elidala laseParis 'lutece. Kamva, kwafunyaniswa ukuba uCp kunye...Funda ngokugqithisileyo -
Into yomhlaba enqabileyo | I-Ytterbium (Yb)
Ngo-1878, uJean Charles kunye noG.de Marignac bafumanisa into entsha enqabileyo yomhlaba kwi "erbium", ebizwa ngokuba yiYtterbium nguYtterby. Ukusetyenziswa okuphambili kwe-ytterbium ngolu hlobo lulandelayo: (1) Isetyenziswe njengento yokukhusela i-thermal. I-Ytterbium inokuphucula kakhulu ukuxhathisa ukubola kwe-zinc efakwe kwi-electrodeposited ...Funda ngokugqithisileyo -
Into yomhlaba enqabileyo | IThulium (Tm)
I-Thulium element yafunyanwa nguCliff eSweden ngo-1879 kwaye yathiywa igama elithi Thulium ngegama lakudala elithi Thule eScandinavia. Olona setyenziso luphambili lwethulium lulandelayo. (1) I-Thulium isetyenziswa njengomthombo wonyango olula kunye nolula. Emva kokulayishwa kwiklasi yesibini entsha emva...Funda ngokugqithisileyo -
Into yomhlaba enqabileyo | ierbium (Er)
Ngowe-1843, uMossander waseSweden wafumanisa ielement element erbium. Iimpawu ezibonakalayo ze-erbium zivelele kakhulu, kunye nokukhutshwa kokukhanya kwi-1550mm ye-EP +, ehlala ixhalabile, inokubaluleka okukhethekileyo kuba lo bude be-wavelength bubekwe ngokuchanekileyo kwi-perturbation ephantsi ye-optic ...Funda ngokugqithisileyo -
Into yomhlaba enqabileyo | Icerium (Ce)
I element 'cerium' yafunyanwa yaze yabizwa ngo-1803 ngu-German Klaus, i-Swedes Usbzil, kunye ne-Hessenger, kwinkumbulo ye-asteroid Ceres eyafunyanwa ngo-1801. Ukusetyenziswa kwe-cerium kunokushwankathelwa kakhulu kule miba ilandelayo. (1) I-Cerium, njengesongezo seglasi, inokufunxa i-ultravio...Funda ngokugqithisileyo -
