Kub muag CAS 7440-54-2 Dy hmoov nqe Dysprosium hmoov High-Entropy Alloys

Gadolinium oxide (Gd2O3) muaj ntau yam kev siv tshuaj, tshuaj ua haujlwm, hluav taws xob, thiab iav ua. Gadolinium oxide yog siv rau hauv kev tsim cov phosphors siv hauv cov raj hauv TV nrog rau kev tsim cov gadolinium yttrium garnets siv nyob rau hauv microwaves thiab cov khoom siv los nqus cov atomic tshua. Gadolinium muaj lub ci xim hlau ci nrog lub ntsej muag daj me ntsis. Nws yog ob qho tib si ductile thiab malleable. Gadolinium yog siv rau ob qho tib si nws lub sijhawm sib nqus siab (7.94uB) thiab hauv phosphors thiab cov khoom siv scintillated. Thaum sib xyaw nrog EDTA dopants, nws yog siv los ua tus neeg sawv cev zoo sib xws rau cov neeg mob uas tau txais kev sib nqus resonance imaging. Nrog nws lub sijhawm sib nqus siab, Gadolinium tuaj yeem txo lub sijhawm so thiab yog li txhim kho lub teeb liab siv. Gadolinium kuj muaj cov khoom siv hlau txawv txawv, nrog tsawg li 1% ntawm Gadolinium txhim kho kev ua haujlwm thiab ua haujlwm ntawm Hlau, Chromium, thiab lwm yam alloys rau kub thiab oxidation. Gadolinium tebchaw kuj siv los ua ntsuab phosphors rau xim TV raj. Gadolinium yog siv los ua Gadolinium Yttrium Garnet (Gd: Y3Al5O12); Nws muaj cov ntawv thov microwave thiab siv rau hauv kev tsim ntawm ntau yam khoom siv kho qhov muag thiab ua cov khoom siv rau cov yeeb yaj kiab magneto-optical. Gadolinium Hlau yog ferromagnetic, ductile thiab malleable hlau, thiab dav siv los ua tshwj xeeb alloys, MRI (magnetic Resonance Imaging), superconductive cov ntaub ntawv thiab sib nqus tub yees. Gadolinium kuj tseem siv nyob rau hauv nuclear marine propulsion systems raws li ib tug burnable tshuaj lom. Nyob rau hauv X-ray systems, gadolinium muaj nyob rau hauv phosphor txheej, tshem tawm nyob rau hauv ib tug polymer matrix ntawm lub detector. Nws yog siv los ua Gadolinium Yttrium Garnet (Gd: Y3Al5O12); Nws muaj cov ntawv thov microwave thiab siv rau hauv kev tsim ntawm ntau yam khoom siv kho qhov muag thiab ua cov khoom siv rau cov yeeb yaj kiab magneto-optical. Gadolinium Gallium Garnet (GGG, Gd3Ga5O12) tau siv los ua cov pob zeb diamond thiab rau lub computer npuas nco. Nws kuj tseem tuaj yeem ua cov khoom siv hluav taws xob hauv Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob (SOFCs). Neutron shielding, garnets hauv microwave lim, phosphor activator, catalyst, scavenger rau oxygen hauv titanium ntau lawm Gadolinium lub ntsiab siv yog raws li nws lub peev xwm nqus neutrons, yog li ua nws zoo tagnrho li aneutron-shielding thiab neutron-absorbing hlau. Nws kuj yog siv los ua tus neeg sawv cev alloying rau steel thiab lwm yam hlau los ua kom cov hlau ua haujlwm ntau dua thiab tuaj yeem tiv taus qhov kub thiab txias.Gadolinium yog siv los ua cov khoom siv hluav taws xob thiab tuaj yeem ua ke nrog yttriumto ua garnets siv hauv microwaves. Gadolinium yog siv los ua ib qho catalyst kom ceev cov tshuaj tiv thaiv kab mob, thiab ua kom cov phosphor tebchaw hauv TV cov ntxaij vab tshaus thiab cam khwb cia filaments hauv cov khoom siv hluav taws xob. Nws kuj yog siv nyob rau hauv high-temperature furnaces. Gadolinium yog paramagnetic nyob rau hauv ib qho chaw txias (tsis muaj zog tshaj ferromagnetic) thiab ua ferromagnetic muaj zog ntawm qhov txias heev. Oxide ntawm Gadolinium ntawv ci yog siv nyob rau hauv kev tswj rods ntawm ib co nuclear reactors. Nws yog siv los ua cov khoom siv hluav taws xob tswj hluav taws xob. Neutron shielding, phosphor activator, catalyst, scavenger rau oxygen hauv titanium ntau lawm. Cov khoom siv hlau uas siv rau hauv magnetic resonance imaging (MRI) thiab lwm txoj kev imaging. Nws tau raug siv los ua gadolinium yttrium garnets, uas muaj kev siv microwave.
