- Nuclear Tshuaj: Lutetium-177 yog ib tug xov tooj cua isotope ntawm lutetium uas yog dav siv nyob rau hauv tsom radionuclide kho mob cancer. Lutetium-177 muaj txiaj ntsig zoo hauv kev kho mob qog nqaij hlav neuroendocrine thiab mob qog noj ntshav prostate los ntawm kev xa cov hluav taws xob hauv zos rau cov qog nqaij hlav cancer thaum txo qis kev puas tsuaj rau cov ntaub so ntswg noj qab haus huv. Daim ntawv thov no qhia txog qhov tseem ceeb ntawm lutetium hauv kev kho mob qog noj ntshav thiab txhim kho cov txiaj ntsig ntawm tus neeg mob.
- Catalysts hauv kev lag luam petrochemical: Lutetium tuaj yeem siv los ua ib qho catalyst rau ntau yam tshuaj tiv thaiv, tshwj xeeb tshaj yog nyob rau hauv kev lag luam petrochemical. Lutetium-based catalysts tuaj yeem txhim kho qhov ua tau zoo ntawm cov txheej txheem xws li hydrocracking thiab isomerization, yog li ua kom cov txiaj ntsig zoo ntawm hydrocarbons. Daim ntawv thov no tseem ceeb heev rau optimizing roj ntau lawm thiab refining txheej txheem.
- Phosphor thiab Display Technology: Lutetium compounds, tshwj xeeb tshaj yog lutetium oxide (Lu2O3), yog siv los tsim phosphor rau teeb pom kev zoo thiab tso saib technology. Lutetium-doped cov ntaub ntawv emit lub teeb thaum zoo siab, ua rau lawv haum rau siv nyob rau hauv LEDs thiab lwm yam zaub systems. Daim ntawv thov no pab txhawb rau kev nce qib ntawm lub zog txuag hluav taws xob thiab txhim kho xim zoo hauv cov khoom siv hluav taws xob.
- Alloying tus neeg sawv cev: Lutetium yog siv los ua tus neeg sawv cev alloying rau ntau yam hlau los txhim kho lawv cov khoom siv dag zog thiab kev tiv thaiv corrosion. Nws feem ntau ntxiv rau npib tsib xee thiab lwm yam tsis tshua muaj lub ntiaj teb alloys kom lawv lub zog thiab thermal stability. Cov lutetium-muaj alloys no yog siv nyob rau hauv aerospace, electronics, thiab lwm yam kev ua tau zoo daim ntawv thov uas muaj kev ntseeg siab thiab durability yog ib qho tseem ceeb.
