Icyumweru gishize (4-7 Mutarama), isoko yisi idasanzwe yatangije umutuku wambere wumwaka mushya, kandi ibicuruzwa nyamukuru byiyongereye mubice bitandukanye.Umucyo udasanzwe isi praseodymium neodymium yakomeje kuzamuka cyane mucyumweru gishize, mugihe isi idasanzwe idasanzwe dysprosium terbium relay hamwe na gadolinium holmium yageze hejuru cyane mumyaka.Muri iki cyumweru, imitekerereze ikabije mu nganda yahurijwe hamwe, amasoko yafashe iya mbere yo kugura no kuyakurikirana, kandi ubushyuhe bw’ubucuruzi muri rusange bwiyongereye vuba.Nyuma yumwaka mushya, igitutu cyamafaranga yinganda cyaragabanutse.Byongeye kandi, ibikoresho bizahagarikwa kandi bigaruke mugihe cyibiruhuko, kandi ubucuruzi bwibigo byimbere kandi byimbere birashyuha vuba
Ku giciro cyo hejuru, icyifuzo cya praseodymium na neodymium kiri hejuru kuruta uko byari byitezwe.Muri icyo gihe, isoko ryuzuyemo ibiteganijwe hamwe nibitekerezo byo gutondekanya isi idasanzwe mumajyaruguru icyumweru gitaha.Mbere y’ibirori, kubera guhagarika Miyanimari by'agateganyo, hari ibintu bimwe na bimwe bikurura isi ku isi idasanzwe, amagambo yavuzwe yari menshi, kandi igiciro cyazamutse kubera kubura inkunga yo gutanga amasoko mu majyepfo.Nyuma yumwaka mushya, ihererekanyabubasha rya praseodymium na neodymium ryatangiye kumenyera kurwego rwo hejuru, rihora rifata kandi rirenga urwego rwo hejuru rwashize, ibikoresho bya magnetiki byo hepfo byari bikenewe gutegurwa, hamwe nigiciro kinini cyo gusinya ibyuma bya dysprosium nibindi ibikoresho bidasanzwe by'isi byazamutse.
Kugeza ubu, bitewe n’ishyaka ryiyongera ryo gutegura ibicuruzwa ku mpande zose z’inganda, igiciro cy’amafaranga cyarazamutse, kandi igipimo nacyo cyiyongereye ugereranije n’ubucuruzi mu gihe cy’ibaruramari.Amarushanwa yabatanga isoko akunda kuba muburyo bwo kwishyura.Ingaruka zibiri zitangwa nibisabwa, ibyago byo kuzamuka kwizamuka rya praseodymium na neodymium nabyo biriyongera.Kugeza ubu, kuzamuka kwisi bidasanzwe gushyigikirwa nibisabwa.Nyamara, icyifuzo gishimangirwa cyane n’ubukungu n’ubukungu bushingiye kuri politiki, kandi bifitanye isano rya bugufi n’ifaranga rinini hamwe n’imiterere ya “karuboni ebyiri” mu gihe cy’icyorezo cy’isi ku isi.
Urebye ishyaka ryiyongera muri iki gihe, kuri ubu, amasoko y'ibikoresho arangije buri cyiciro cy'inganda ahura n'ingaruka zikomeye.Iterambere ridafite ishingiro ryangije cyane gutegura ibicuruzwa bisanzwe no kubyaza umusaruro hejuru no hepfo.Muri icyo gihe, inganda za neodymium fer boron nazo ntizatinyuka gutanga ibicuruzwa kumanuka.Nubwo igiciro cyibyuma bya magnetiki cyiyongera hamwe nibishoboka byinshi, ibicuruzwa bimwe byatakaye icyarimwe, izamuka ryihuse akenshi rizagabanya igihe cyo kuzamuka kwisoko kandi bigira ingaruka kumajyambere yurwego rwinganda.
