Neodmium, tinye tebụl 60 nke tebụl.
A na-ejikọ neoodmium na paraseymium, nke a bụ lanthanide na ihe ndị yiri ya. N'afọ 1885, mgbe Swedish chemistisy Mosander chọpụtara ngwakọta nkelanthanumna paseodmium na neoodmium, ndị Austrians Wellsbach nke ọma kewapụrụ ụdị abụọ "ụwa dị ụkọ": neoodmium oxide naPraseodmium Oxide, ma mesịa kewapụ yaneodmiumnaPraseodmiumsite na ha.
Neadmium, ọla ọcha ọcha na ihe ndị na-arụ ọrụ kemịkal, nwere ike ịme ọsọ ọsọ na ikuku; Yiri onye na-eto eto, o mere nwayọ na mmiri oyi ma hapụ gas hydrogen ngwa ngwa. Neoodmium nwere obere ọdịnaya n'ime ala nke ụwa na-adị ugbu a na nke ndị Monazite na Basta na nke na-enweghị atụ.
A na-eji Neodmium na-ejikarị iko iko na narị afọ nke 19. Mgbe oleneodmium oxidegbazee n'ime iko, ọ ga-amịpụta ụdị dị iche iche sitere na pink na-acha anụnụ anụnụ na-acha anụnụ anụnụ dabere na isi ọkụ ọkụ ọkụ. Eledala iko pụrụ iche nke neodmium anya "neoodmium iko". Ọ bụ "obi" lasers, na àgwà ya na-ekpebi n'ụzọ nwere ike ịdị mma nke laser arụpụta. A maara ya ugbu a dị ka laser na-arụ ọrụ ọkara nke ụwa nke nwere ike iwepụta ike kachasị. Ionzọ neoodmium eons na neodmium iko bụ isi ihe na-agba ọsọ na ala na "skycraper" larịị nke nanojoule na-eleghara anya 10-9 laser ike na ọkwa nke "obere anyanwụ". Ngwaọrụ neodmium nke kachasị ukwuu n'ụwa, emegoro teknụzụ na-aga n'ihu na-agbaze iko neodmium ka ọ bụrụ ọkwa ọhụrụ ma depụta ya dị ka teknụzụ asaa na mba. N'afọ 1964, akara ngosi nke Spanghai na ezigbo arụ ọrụ nke sayensị nke sayensị na-eme ka nyocha dị na nzere anọ na-aga n'ihu, na-edinarị na nnwale nke neodmium iko. Mgbe iri afọ nke njem nyocha, emechara nnukwu ihe mberede na afọ iri gara aga. Ndị otu Hu Lili bụ nke mbụ n'ụwa ka ha mata Shanghai Ultra Ugbo na Ultra obere laser na 10 Watt Laser arụpụta. Isi ya bụ ijikọ teknụzụ igodo nke nnukwu na arụmọrụ dị elu na-arụ ọrụ na-arụ ọrụ. Ya mere, onye China Academy of Sciences of Sknghai Institute of SkyPer na igwe na-adịbeghị abụrụla ụlọ ọrụ mbụ n'ụwa iji na-eme ka teknụzụ mmepụta usoro zuru ezu.
A nwekwara ike iji Neodmium mee ihe kachasị mara mma nke na-adịgide di ike - neoodmium ígwè boron bon alloy alloy. Neoodmium Ígwè alloy bụ ụgwọ ọrụ nke Japan dị na 1980s mebie ihe zuru ezu na United States. Ọkà mmụta sayensị nke sayensị Masato Zukawa mepụtara ụdị ndọta ọhụrụ, nke bụ ndọhọta alloy mejupụtara ihe atọ: neodmium, ígwè, na boron. Ndị ọkà mmụta sayensị China mepụtakwara usoro mgbasa ozi ọhụrụ.
