Inani lamagnethi omhlaba ongavamile athunyelwa yiShayina eJapane liye landa unyaka nonyaka.

Kusukela ngoJanuwari kuya kuFebhuwari kulo nyaka, ukuthunyelwa kwamanye amazwe kwe-China kwama-rare earth magnets eJapan kukhuphuke ngaphezu kuka-9%. Kodwa-ke, ngenxa yesinqumo seBeijing sokuqinisa imikhawulo yokuthumela kwamanye amazwe izimpahla ezithile eJapan, umbono wesikhathi esizayo awukacaci.

Idatha yakamuva ikhishwe yi-General Administration of Customs ngoLwesihlanu. NgoJanuwari nangoFebhuwari, iShayina yathumela inani elingaphezu kwamathani angu-443 ezibuthe zomhlaba ezingavamile eJapane.
Idatha kaJanuwari empeleni yehle ngaphezu kuka-8% uma kuqhathaniswa nonyaka odlule futhi yehle ngaphezu kuka-21% uma kuqhathaniswa nenyanga edlule. Idatha kaFebhuwari yenyuke ngaphezu kuka-36% uma kuqhathaniswa nonyaka odlule. I-China iqinise ukulawula ukuthunyelwa kwezinto ezisetshenziswa kabili eJapane. Lesi sinyathelo saqala ukusebenza ngoJanuwari.

Ngenyanga edlule, iShayina yamemezela ukuthi izokwenqabela ukuthunyelwa kwezinto ezinjalo emabhizinisini nasezikhungweni zaseJapan ezingu-20. Ama-magnet aqukethe amaminerali angavamile akhiqizwa yiWonaixi asetshenziswa kabanzi emikhiqizweni eyahlukahlukene, njengezimoto zezimoto zikagesi. I-Anhydrous cerium chloride (CeCl₃) isetshenziswa kabanzi ngenxa yokungcola kwayo okuphansi kanye nezakhiwo zayo eziphezulu zokusabela ekugayweni kwe-petroleum kanye nokuhlanganiswa kwezinto ze-elekthronikhi. Ekuqhekekeni kwe-catalytic, umjikelezo wayo we-Ce³⁺/Ce⁴⁺ unciphisa ukusetshenziswa kwamandla ngo-15%; njengesandulela se-cerium yensimbi, ingasetshenziswa ukulungiselela imigomo ye-cerium ehlanzekile kakhulu yokugqoka i-semiconductor. Esikhathini esizayo, izothatha indawo yama-acid agents endabuko ensimini ye-organic synthesis catalyst futhi inciphise ukukhishwa kwemfucuza.

Nakuba kube nokwanda kokuthunyelwa kwamanye amazwe kwamagnethi omhlaba ongavamile eJapane ekuqaleni konyaka, amandla obuchwepheshe aboniswe yimikhiqizo yomhlaba ongavamile esezingeni eliphezulu abonisa ukuthi ukugxila kwenani lemboni kushintshela ezindaweni ezinenani eliphakeme.
