Kuleli sonto (7.4-7.8, okufanayo ngezansi), imikhiqizo yomhlaba engavamile ekhanyayo futhi elula emakethe yomhlaba engavamile ibonise ukwehla, futhi izinga lokwehla kokukhanya okungavamile komhlaba kwakushesha.Amathuba okuthi iminotho emikhulu eYurophu nase-United States iwele ekuntekeni komnotho engxenyeni yesibili yonyaka asobala, futhi imiyalo yokuthekelisa ngokusobala ibe nezimpawu zokuwohloka.Nakuba ukunikezwa komfula nakho kwehlile, uma kuqhathaniswa nezinga elintengantengayo lesidingo, kubonakala sengathi kusenensada.Ithemba eliphelele lenyuka nomfula lenyuke kuleli sonto, futhi umhlaba okhanyayo nolula ongavamile uwele esimweni esisobala sokuqedwa kwamabhidi.
Kuleli sonto, imikhiqizo ye-praseodymium ne-neodymium iqhubekile nokuthambekela kokwehla kweviki eledlule.Ngokuhoxiswa kwamandla ahlukahlukene, ukufunwa nokulindelwe okubuthakathaka, okuqhutshwa ingcindezi yokubhida, isivinini sokulungiswa kokwehla kwamabhizinisi akhuphukayo sashesha kakhulu.Isinyathelo semakethe kwaba umthengi, futhi intengo yokuthenga ishaye phansi ngokuphindaphindiwe ngenxa yethonya elingokwengqondo elithi "ukuthenga kodwa ungathengi".
Ithintwa i-praseodymium ne-neodymium, isidingo seminye imikhiqizo esindayo engavamile yomhlaba nayo iyabanda, futhi imikhiqizo ye-gadolinium yehle kancane.Kodwa-ke, ngenxa yokwehla kancane kwentengo yezimayini zomhlaba ezingavamile, imikhiqizo ye-dysprosium yazinza ekupheleni kwesonto eledlule, futhi yehla kancane ngokuhambisanayo ngenxa yomthelela wesimo sengqondo sisonke.I-Dysprosium oxide yehle ngo-8.3% kusukela ngo-Ephreli.Ngokuphambene, inani eliphakeme lomlando lemikhiqizo ye-terbium ligcinwe isigamu sonyaka, futhi ukusetshenziswa kwazo zonke izinhlangothi ochungechungeni lwezimboni kwehlisiwe ngokwesaba amanani aphezulu kanye nokungabaza.Kodwa-ke, uma kuqhathaniswa, isidingo se-terbium ezikhathini zamuva nje sithuthukile uma siqhathaniswa nesikhathi sangaphambilini.Umthamo wezimpahla eziningi emakethe mncane futhi ngokuvamile kunamanani aphezulu, ngakho-ke ukuzwela ezindabeni zemakethe kubuthakathaka kancane.Ku-terbium ngentengo yamanje, kungcono ukusho ukuthi ingaphansi kokulawulwa kwevolumu ephelele kunokwandisa indawo yokusebenza kanye nesikhathi sokwehla, Lokhu kukhulise ingcindezi yokuzinza intengo ye-terbium, ngakho-ke uhla lwe-bearish abanikazi bempahla bemboni baphansi kakhulu kunalabo be-dysprosium.
Ngokombono wamanje we-macro, idola laseMelika laphuka lakhuphuka.Ezinye izindaba bezithi kuzodambisa ukuntengantenga okuzayo e-United States, uhulumeni wase-US bekulindeleke ukuthi axegise intela e-China, kanti ubhubhane ezingxenyeni eziningi zomhlaba lwalwa.Ngaphezu kwalokho, ubhadane ezingxenyeni ezihlukahlukene zezwe lwaphindeka, ngakho isimo sengqondo sasingenathemba.Ngokombono wezinto eziyisisekelo zamanje, ukwehla ngokushesha kwamanani entengo yomhlaba engavamile kuye kwabangela ingcindezi ethile ekuthengeni okuphansi komfula.Njengamanje, izinkomba zomhlaba ezingavamile zasekhaya akulindelekile ukuthi zande.Amabhizinisi amaningi asekhaya azophothula izinkomba eziningi kulo nyaka.Imiyalo yenhlangano yesikhathi eside iqinisekisa isidingo esithile esingaphansi komfula, futhi inani elincane lesidingo lingase liholele ekubhideni okukhulu.
