Kule veki (i-7.4-7.8, efanayo ngezantsi), ukukhanya kunye nokukhanya okunqabileyo kweemveliso zomhlaba kwimarike yomhlaba onqabileyo kubonise ukuhla, kunye nesantya sokukhanya komhlaba onqabileyo ngokukhawuleza.Amathuba okuba uqoqosho oluphambili lwaseYurophu nase-United States luwele ekudodobaleni kwezoqoqosho kwisiqingatha sesibini sonyaka kucacile noko, kwaye imiyalelo yokuthumela impahla ngaphandle iye yafumana iimpawu zokuwohloka.Nangona unikezelo lomlambo nalo lwehlile, xa kuthelekiswa neqondo elibuthathaka lemfuno, kubonakala ngathi kusekho intsalela.Ukungathembeki okungaphezulu komsinga kunyukile kule veki, kwaye ukukhanya kunye nokukhanya okunqabileyo komhlaba kuwele kwimeko ecacileyo yokupheliswa kwebhidi.
Kule veki, iimveliso zepraseodymium kunye neodymium ziqhubekile nokuhla kweveki ephelileyo.Ngokurhoxiswa kwemikhosi eyahlukeneyo, imfuno kunye nolindelo olubuthathaka, oluqhutywa luxinzelelo lwebhidi, isantya sohlengahlengiso esihlayo samashishini anyukayo sakhawuleziswa kakhulu.Inyathelo lemarike lalingumthengi, kwaye ixabiso lentengiselwano labetha phantsi ngokuphindaphindiweyo ngenxa yempembelelo yengqondo "yokuthenga kodwa ungathengi".
Ichatshazelwa yipraseodymium kunye ne-neodymium, imfuno yezinye iimveliso zomhlaba ezinqabileyo ezinzima nazo ziyabanda, kwaye iimveliso zegadolinium zehle kancinci.Nangona kunjalo, ngenxa yokuhla okucothayo kwixabiso lemigodi yomhlaba enqabileyo enzima, iimveliso ze-dysprosium zizinzile ekupheleni kweveki ephelileyo, kwaye zafumana ukwehla okuncinci ngokuhambelanayo ngenxa yempembelelo yomoya jikelele.I-Dysprosium oxide yehle nge-8.3% ukususela ngo-Epreli.Ngokwahlukileyo, ixabiso lembali eliphezulu leemveliso ze-terbium ligcinwe isiqingatha sonyaka, kwaye ukusetyenziswa kwawo onke amaqela kwi-industrial chain chain kuye kwancitshiswa ngenxa yokwesaba amaxabiso aphezulu kunye nokungabaza.Nangona kunjalo, ngokwentelekiso, imfuno ye-terbium kumaxesha amva nje iphucukile xa kuthelekiswa nexesha elidlulileyo.Umthamo wempahla eninzi kwimarike incinci kwaye kukho amaxabiso aphezulu ngokubanzi, ngoko ke ubuntununtunu kwiindaba zentengiso bubuthathaka kancinci.I-terbium ngexabiso langoku, kungcono ukutsho ukuba iphantsi kolawulo lomthamo opheleleyo kunokwandisa indawo yokusebenza kunye nexesha lokuhla, Oku kuye kwandisa uxinzelelo lokuzinzisa ixabiso le-terbium, ngoko ke uluhlu lwe-bearish abanini bempahla kwishishini basezantsi kakhulu kunabo bedysprosium.
Ngokwembono yangoku enkulu, idola yaseMelika yaphuka kwaye yaphakama.Ezinye iindaba zathi ibikukunciphisa ukudodobala okuzayo e-United States, urhulumente wase-US bekulindeleke ukuba aphumze amaxabiso e-China, kwaye ubhubhani kwiindawo ezininzi zehlabathi ubuyile.Ukongezelela, lo bhubhani wawuphindaphindwa kwiindawo ezahlukahlukeneyo zelo lizwe, ngoko abantu babebonakala bephelelwe lithemba.Ngokwembono yeziseko zangoku, ukwehla ngokukhawuleza kwamaxabiso omhlaba anqabileyo kubangele uxinzelelo oluthile ekuthengeni izinto ezisezantsi.Okwangoku, izikhombisi zomhlaba ezinqabileyo zasekhaya akulindelekanga ukuba zande.Uninzi lwamashishini emveliso yasekhaya aya kugqibezela uninzi lwezalathisi kulo nyaka.Ii-odolo zexesha elide zonxulumano ziqinisekisa imfuno ethile esezantsi, kwaye inani elincinci lemfuno linokukhokelela kwibhidi eqatha.
