DaahfurkiiNeodymium
Karl von Welsbach (1858-1929), daahfurahaNeodymium
Sannadkii 1885kii, waxa helay farmashiistaha Australiya Carl Auer von WelsbachneodymiumVienna.Wuu kala saarayneodymiumiyopraseodymiumka simmetricalneodymiumagabka iyadoo la kala saarayo ammonium dinitrate tetrahydrate crystalline iyo nitric acid, oo lagu kala soocay iyada oo loo marayo falanqaynta spectral.Si kastaba ha ahaatee, may ahayn ilaa 1925 in ay ku kala tageen qaab saafi ah.
Laga soo bilaabo 1950-meeyadii, daahir-sare (in ka badan 99%)neodymiumInta badan waxaa lagu helay habka sarrifka ion ee monazite.Birta lafteeda waxa lagu helaa korontolaysiis ee milixdeeda halide.Waqtigan xaadirka ah, inta badanneodymiumwaxaa laga soosaaraa dhagaxa Bastana (Ce, La, Nd, Pr) CO3F waxaana lagu sifeeyaa soo saarista dareeraha.Nadiifinta sarrifka Ion waxaa loo hayaa diyaarinta nadiifinta ugu sareysa (sida caadiga ah>99.99%).Sababtoo ah dhibka ah in meesha laga saaro raadadkii ugu dambeeyaypraseodymiumwaagii wax soo saarka ee ku tiirsanaanta tignoolajiyada kiristaalka tallaabo-tallaabo, horeneodymiumdhalooyinka la soo saaray 1930-kii ayaa lahaa midab guduudan ama oranji ah oo saafi ah marka loo eego noocyada casriga ah.
Biraha NeodymiumWaxay leedahay dhalaal bir ah oo qalin ah oo dhalaalaya, barta dhalaalaysa 1024 ° C, iyo cufnaanta 7.004g/cm ³, Waxay leedahay paramagnetism.Neodymiumwaa mid ka mid ah kuwa ugu firfircoonbiraha dhulka dhif ah, kaas oo si degdeg ah oksidizes iyo madoobaada hawada, samaynta lakabka oksaydh ah ka dibna siigo, soo bandhigay birta si ay u sii oksijiinta.Sidaa darteed, cabbir sentimitir ahneodymiummuunada si buuxda ayaa oksaydhaysan loogu sameeyaa hal sano gudaheed.Si tartiib ah uga falceli biyo qabow oo degdeg u gali biyo kulul.

Waxqabadka laysarka eeneodymiumwaxaa sabab u ah kala guurka 4f orbital electrons ee u dhexeeya heerarka tamarta kala duwan.Qalabkan laser-ka ah ayaa si weyn loogu isticmaalaa isgaarsiinta, kaydinta macluumaadka, daaweynta caafimaadka, farsamaynta farsamada, iyo qaybaha kale.Iyaga ka mid ah,yttrium aluminiumgarnet Y3Al5O12: Nd (YAG: Nd) waxaa si weyn loogu isticmaalaa waxqabadkeeda wanaagsan, iyo sidoo kale Nd dopedgadolinium scandiumgallium garnet oo leh waxtar sare.

Isticmaalaha ugu weyn eeneodymiumwaa bir neodymium boron magnet joogto ah.Neodymium iron boron magnets waxay leeyihiin wax soo saar tamar bir ah oo sarreeya waxaana loo yaqaan 'boqorka magnets-ka joogtada ah' ee casriga ah.Waxaa si weyn loogu isticmaalaa warshadaha sida elektiroonigga ah iyo mishiinada sababtoo ah waxqabadkooda wanaagsan.Francis Wall, oo ah borofisar macdan qodista ka dhiga Cumburn School of Mining ee Jaamacadda Exeter ee UK, ayaa yidhi: “Marka la eego magnets-ka, runtii ma jiro tartan lala galoneodymium.”Horumarka guusha leh ee Alfa magnetic spectrometer waxay calaamad u tahay in sifooyinka birta ee kala duwan ee Shiinaha ee birta neodymium ee boron magnets ay gaareen heerar heer caalami ah.
Neodymium magnet ku saabsan disk adag
Neodymiumwaxaa loo isticmaali karaa in lagu soo saaro dhoobada, galaas guduudan oo dhalaalaya, dhagaxyo macmal ah oo leysarka ah, iyo galaas gaar ah oo sifeyn kara fallaadhaha infrared.Si wada jir ah loo isticmaalopraseodymiumsi loo sameeyo muraayadaha muraayadaha afuufaya shaqaalaha.
Ku darida 1.5% ilaa 2.5% nanoneodymium oxideilaa magnesium ama aluminium aluminium waxay hagaajin karaan waxqabadka heerkulka sare, xajinta hawada, iyo iska caabbinta daxalka ee daawaha, waxaana si ballaaran loo isticmaalaa sida qalabka hawada.
Nanometeryttrium aluminiumgarnet lehneodymium oxidewaxa ay abuurtaa laydhka laysarka ee hirarka gaaban, kuwaas oo si weyn loogu isticmaalo warshadaha alxanka iyo jarista alaabada khafiifka ah ee dhumucdeedu ka yar tahay 10mm.

Dhaqanka caafimaadka, nanoyttrium aluminiumleysarka garnet oo leh nanoNadiifin Sare 99.9% Neodymium Oxide CAS Maya 1313-97-9 (epomaterial.com)waxaa loo isticmaalaa halkii mindiyo qalliin si meesha looga saaro nabarrada qaliinka ama jeermiska.
Neodymiumgalaaska waxaa lagu sameeyaa iyadoo lagu darayneodymium oxidesi ay dhalaaliso galaaska.Caadi ahaan, lavender ayaa soo muuqdaneodymiummuraayadda hoosteeda iftiinka qoraxda ama iftiinka iftiinka, laakiin waxay u muuqataa buluug khafiif ah oo hoos yimaada iftiinka fluorescent.Neodymiumwaxaa loo isticmaali karaa in lagu midabeeyo muraayadaha jilicsan sida violet saafi ah, burgundy, iyo cawl diiran.
Neodymiumquraarad
Iyadoo horumarinta sayniska iyo tignoolajiyada iyo ballaarinta iyo fidinta tignoolajiyada dhifka ah ee dhulka,neodymiumwaxay yeelan doontaa meel ballaadhan oo lagu isticmaalo.
