Praseodymium feem ntau yog siv los ua tus neeg sawv cev alloying nrog magnesium los tsim cov hlau muaj zog siv hauv cov tshuab dav hlau. Nws tseem yog ib feem ntawm mischmetal, ib yam khoom uas siv los ua flints rau lighters, thiab nyob rau hauv cov pa roj carbon arc teeb, siv nyob rau hauv lub motion picture industry rau studio teeb pom kev zoo thiab projector teeb.
Vim li cas praseodymium siv?
Praseodymium yog siv hauv ntau yam alloys. Lub siab-lub zog alloy nws cov ntaub ntawv nrog magnesium yog siv nyob rau hauv aircraft engine. Mischmetal yog ib qho alloy uas muaj li ntawm 5% praseodymium thiab yog siv los ua flints rau luam yeeb lighters. Praseodymium kuj tseem siv rau hauv cov hlau nplaum ruaj khov.
Dab tsi ua rau praseodymium tshwj xeeb?
Praseodymium yog qhov txawv ntawm qhov nws yog paramagnetic ntawm txhua qhov kub siab tshaj 1 K. Lwm cov hlau tsis tshua muaj hauv ntiaj teb yog ferromagnetic lossis antiferromagnetic ntawm qhov kub thiab txias. Ntuj praseodymium muaj ib qho isotope ruaj khov, praseodymium-141.
Neodymium praseodymium siv rau dab tsi?
Ua ke nrog neodymium, praseodymium feem ntau yog siv hauv cov hlau nplaum neodymium siv hauv thaj chaw loj hlob ntawm kev siv tshuab siab. Praseodymium thiab neodymium oxides yog siv nyob rau hauv welder thiab iav blower goggleslos tiv thaiv lub qhov muag ntawm daj flare thiab UV teeb.
Puas yog txiv neej praseodymium tsim?
Hauv xyoo 1841, Mosander tshaj tawm tias nws tau txais ob lub ntsiab lus tshiab los ntawm cerite. Nws hu cov ntsiab lus nolanthanum thiab didymium. … Qhov "cov ntsiab lus" tshiab no tau muab los ua kev sib xyaw ntawm ob lub ntsiab lus tshiab, tam sim no hu ua neodymium thiab praseodymium. Tus txiv neej uas tsim qhov kev tshawb pom no yog Auer.
