Neodymium, element 60 ye tafura yemaperi.
Neodymium inosanganiswa ne praseodymium, zvese zviri zviviri marara nezvinhu zvakafanana. Muna 1885, mushure mekunge Sweden Chemist Sheriya akawana musanganiswa weLanthanumuye praseodymium uye neodrium, Austria welsbrach akapatsanura mbiri dze "nyika yepasi": Neodymium oxide uyepraseodymium oxide, uye pakupedzisira vakaparadzaniswaneodymiumuyePraseodymiyokubva kwavari.
Neodymium, sirivha chena simbi ine basa rinoshanda zvemakemikari, nekukurumidza nekukurumidza oxidize mumhepo; Zvakafanana nePraseodymium, zvinobata zvishoma nezvishoma mumvura inotonhora uye nekukurumidza kuburitsa hydrogen gasi mumvura inopisa. Neodymium ine yakaderera mukati mekuputika kwepasi uye inonyanya kuvapo muMonazi uye Bastnaesite, ine huwandu hwaro hwechipiri kune cerium.
Neodymium yakanyanya kushandiswa segirazi remahara muzana ramakore re19. RiniNeodymium oxideyakanyungudutswa mugirazi, yaizoburitsa mimvuri dzakasiyana-siyana kubva kune inodziya pink kune bhuruu zvichienderana neye ambient mwenje wechiedza sosi. Usarerutsa girazi rinokosha reNeoodymium ion inonzi "neodymium girazi". "Mwoyo" lasers, uye hunhu hwayo hunosarudza zvakananga uye hunhu hwe laser mudziyo wekubuda simba. Iyo yazvino inozivikanwa seye laser inoshanda svikiro pasi pano rinogona kuburitsa simba rakanyanya. Iyo neodymium ion in neodymium girazi ndiyo kiyi yekumhanyisa kumusoro uye pasi "yemagetsi emagetsi ekuchinja, iyo inogona kukwidziridzwa nanojing nanojeli yeiyo Nanojera 10-9 laser simba re" zuva diki ". Iyo yepasi rose neodymium girazi laser Fusion mudziyo weUnited States, akasimudza tekinoroji yekunyungudika yeiyo neodymium girazi kusvika padanho rutsva uye rakanyorwa seyekutumira kweinomwe zvishamiso zvinoshamisa munyika. Muna 1964, iyo Shanghai Institute yeChictics neChina Chikoro cheChinese chesainzi yakatanga kutsvagisa kiyi yekiyi yekunyungudika, kunyatsojeka, kugadzirisa uye kuongororwa kwegirazi reiyo neodymium. Mushure memakumi emakore ekuongorora, kupwanya kukuru kwakazoitwa mumakore gumi apfuura. Chikwata cheUri chiri chekutanga munyika kuti uzive iyo shanghai Ultra yakanyanya uye Ultra pfupi laser mudziyo ne 10 watt laser kubuda. Yayo musimboti ndeyekushanda kiyi kiyi tekinoroji yeakakura-chiyero uye yakakwirira-performance laser nd girazi grass batch kugadzirwa. Naizvozvo, nhoroondo yeChinese yeScience Shanghai Institute yeAptices uye Chinoita Machina Chave Chinyorwa Chekutanga Munyika Kuzvimiririra Kuzvimiririra Kurovedza muviri Kugadzira Tekinoroji yeLaser nd Girazi.
Neodymium inogona zvakare kushandiswa kugadzira iyo ine simba zvachose magmet inozivikanwa - Neodymium iron boron alloy. Neodymium iron boron alloy yaive mubairo unorema wakapihwa neJapan muma1980 ekupwanya monopoly yevagari vazhinji vemutori muUnited States. Masayendisiti Masayewa Zuokawa rudzi rutsva rwemagineti isingagumi, iyo iri magineti yemagineti inoumbwa nezvinhu zvitatu: neodymium, simbi, uye Boron. Masayendisiti eChinese akagadzirawo nzira itsva yekuchinjisa, kushandisa induction kupisa kwechinyakare kutadza kukura kwemagineti, kupfupikisa kutenderera kwekutanga, uye kuderedza kuderedza mari yekugadzira.
