Neodymium, mmewere 60 nke tebụl oge.
Ejikọtara Neodymium na praseodymium, ha abụọ bụ Lanthanide nwere ihe ndị yiri ya.Na 1885, mgbe Swedish chemist Mosander chọpụtara ngwakọta nkelanthanumna praseodymium na neodymium, ndị Austrian Welsbach nke ọma kewapụrụ ụdị "ụwa na-adịghị ahụkebe" abụọ: neodymium oxide napraseodymium oxide, ma mesịa kewapụneodymiumnapraseodymiumsite na ha.
Neodymium, ọla ọcha ọcha nke nwere kemịkalụ kemịkalụ na-arụ ọrụ, nwere ike ikuku oxidize ngwa ngwa;Yiri praseodymium, ọ na-eji nwayọ na-emeghachi omume na mmiri oyi ma na-ahapụ ngwa ngwa hydrogen gas n'ime mmiri ọkụ.Neodymium nwere ọdịnaya dị ala n'ime eriri ụwa ma dị na monazite na bastnaesite, yana ụbara ya nke abụọ na cerium.
A na-ejikarị Neodymium mee ihe dị ka agba na iko na narị afọ nke 19.Mgbe oleneodymium oxideagbazere ka ọ bụrụ iko, ọ ga-emepụta ndo dị iche iche sitere na pink na-ekpo ọkụ ruo na-acha anụnụ anụnụ dabere na isi iyi ọkụ ambient.Elelelịla iko pụrụ iche nke ion neodymium a na-akpọ “iko neodymium”.Ọ bụ "obi" nke lasers, na àgwà ya na-ekpebi kpọmkwem ike na àgwà nke mmepụta ike nke ngwaọrụ laser.A maara ya ugbu a dị ka onye na-arụ ọrụ laser na Ụwa nke nwere ike ịmepụta ike kachasị elu.The neodymium ions na neodymium iko bụ isi ihe na-agba ọsọ na ala na "skyscraper" nke ike ọkwa na-akpụ kacha ike laser n'oge nnukwu mgbanwe usoro, nke nwere ike na-amụba nanojoule na-adịghị elebara larịị 10-9 laser ume na larịị nke.

A pụkwara iji Neodymium mee ka a mara ihe magnet na-adịgide adịgide kachasị ike - neodymium iron boron alloy.Neodymium iron boron alloy bụ ụgwọ ọrụ dị arọ nke Japan nyere na 1980 iji mebie ikike nke General Motors na United States.Ọkà mmụta sayensị nke oge a Masato Zuokawa chepụtara ụdị ndọta ọhụrụ na-adịgide adịgide, nke bụ magnet alloy nke nwere ihe atọ mejupụtara: neodymium, iron, na boron.Ndị ọkà mmụta sayensị nke China emepụtala usoro ọhụụ ọhụrụ, na-eji induction kpo oku sintering kama ịmegharị omenala na ọgwụgwọ okpomọkụ, iji nweta njupụta nke ihe karịrị 95% nke uru ihe omimi nke magnet, nke nwere ike izere oke ọka nke magnet, belata. usoro mmepụta ihe, ma na-ebelata ọnụ ahịa mmepụta ihe.
