Waizviziva here? Neodymium yakawanikwa naCarl Auer muVienna muna 1885. Auer yakaparadzana neodymium uye praseodymium kubva musanganiswa we neodymium uye praseodymium ne spectral analysis uchidzidza diammonium nitrate tetrahydrate. Auer akatumidza neodymium "Neodymium" mukukudza weGerman chemist Welsbach, akawana yttrium, kubva pashoko rechiGiriki rekuti "neos", rinoreva "nyowani", uye "didymos", zvinoreva "mapatya".
Mushure mekuwanikwa kwaAuer neodymium, mamwe makemikari akanga asina chokwadi nekuwanikwa. Zvisinei, muna 1925, muenzaniso wekutanga wesimbi yakachena yakagadzirwa. Mumakore ekuma1950, Lindsay Chemical Division yakacheneswa neodymium neion exchange. Kwenguva yakati mushure mekuwanikwa kwayo, neodymium haina kushandiswa zvakanyanya. Nekudaro, nekuvandudzwa kwesainzi uye tekinoroji, neodymium yakatanga kushandiswa muminda yakawanda nekuda kwekusiyana kwayo kwemuviri nemakemikari. Mumakore ekuma1930, bhizimusi neodymium raishandiswa sedhayi regirazi, uye girazi reneodymium raishandiswa kugadzira girazi rine tsvuku tsvuku kana orenji.
Neodymium yakwezva kutarisisa kwakawanda nekuda kwekusiyana kwayo kwemuviri nemakemikari zvimiro. Mumakore achangopfuura, kushandiswa kwayo mundima dzakawanda kwave kuchiwedzera, uye ukoshi hwayo hwave huchiwedzera kuoneka. Saka, chii chakasarudzika nezve neodymium? Nhasi, ngatiburitsei chakavanzika cheneodymium.
Zvishandiso zveNeodymium
1. Magnetic Materials: Kunyanya kushandiswa kweneodymium kuri mukugadzirwa kwemagineti echigarire. Kunyanya, neodymium iron boron magnets (NdFeB) ari pakati peakasimba anozivikanwa magineti echigarire. Aya magineti anoshandiswa zvakanyanya kushandura uye kuchengetedza simba mumidziyo yakaita semotor, jenareta, magineti resonance imaging zvishandiso, hard disk drive, vatauri, uye mota dzemagetsi.
