Application:
Gadolinium Metal is ferromagnetic, ductile uye simbi inogoneka, uye inoshandiswa zvakanyanya kugadzira specialty alloys, MRI(magnetic Resonance Imaging), superconductive zvinhu uye magineti firiji.Gadolinium inoshandiswawo munyukireya marine propulsion systems semuchetura unopisa.Gadolinium se phosphor inoshandiswawo mune mamwe mifananidzo.Mu X-ray systems, gadolinium inowanikwa mu phosphor layer, yakamiswa mu polymer matrix pa detector.Inoshandiswa kugadzira Gadolinium Yttrium Garnet (Gd:Y3Al5O12);ine microwave application uye inoshandiswa mukugadzira akasiyana-siyana optical components uye se substrate material yemagneto-optical films.Gadolinium Gallium Garnet (GGG, Gd3Ga5O12) yakashandiswa kutevedzera madhaimani uye nekombuta bubble memory.Inogonawo kushanda se electrolyte muSolid Oxide Fuel Cells (SOFCs).
