Daim ntawv thov

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. Gadolinium ua phosphor kuj tseem siv rau hauv lwm cov duab. 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).
