Daim ntawv thov

Sib nqus Resonance Imaging (MRI): Gadolinium yog dav siv nyob rau hauv kev kho mob, tshwj xeeb tshaj yog raws li ib tug MRI contrast agent. Gadolinium-based compounds txhim kho qhov sib txawv ntawm cov duab los ntawm kev hloov cov khoom sib nqus ntawm cov dej nyob ze, yog li qhia cov qauv sab hauv kom meej meej. Daim ntawv thov no tseem ceeb heev rau kev kuaj mob ntau yam mob, nrog rau cov qog nqaij hlav thiab cov kab mob neurological.
Neutron capture thiab nuclear applications: Gadolinium muaj lub siab neutron ntes hla ntu, ua rau nws muaj txiaj ntsig hauv nuclear reactors thiab tiv thaiv hluav taws xob. Nws feem ntau yog siv los tswj cov pas nrig los pab tswj cov txheej txheem fission thiab tswj cov reactor stability. Gadolinium-raws li cov ntaub ntawv kuj tseem siv nyob rau hauv kev tshawb nrhiav hluav taws xob thiab daim ntawv thov kev tiv thaiv los txhim kho kev nyab xeeb ntawm kev tsim hluav taws xob nuclear thiab kho hluav taws xob kho mob.
Cov khoom siv hlau nplaum: Gadolinium yog siv los tsim ntau yam khoom sib nqus, nrog rau cov hlau nplaum ruaj khov ua haujlwm siab. Nws cov khoom sib nqus tshwj xeeb ua rau nws haum rau cov ntaub ntawv khaws cia, motors, thiab sensors. Gadolinium-raws li alloys kuj tseem siv los tsim cov tshuab magnetic refrigeration, muab cov kev daws teeb meem rau kev txuag hluav taws xob.
Phosphor thiab Display Technology: Gadolinium compounds yog siv los tsim phosphor rau teeb pom kev zoo thiab kev siv tshuab. Gadolinium oxysulfide (Gd2O2S) yog ib qho khoom siv phosphor feem ntau siv hauv cathode ray hlab (CRTs) thiab lwm yam khoom siv. Daim ntawv thov no pab txhawb rau kev nce qib hauv cov teeb pom kev zoo hluav taws xob thiab txhim kho xim zoo hauv cov khoom siv hluav taws xob.
