Qhov tseem ceeb ntawm kev siv scandium

Qhov tseem ceeb ntawm kev siv scandium

Kev siv ntawmscandium(raws li cov khoom siv tseem ceeb, tsis yog rau doping) yog concentrated nyob rau hauv lub ci ntsa iab heev, thiab nws tsis yog ib qho exaggeration hu nws Leej Tub ntawm lub teeb.

1. Scandium sodium teeb

Thawj riam phom khawv koob ntawm scandium yog hu ua scandium sodium teeb, uas tuaj yeem siv los coj teeb rau ntau txhiab tsev neeg. Qhov no yog hlau halide hluav taws xob lub teeb qhov chaw: sodium iodide thiab scandium iodide raug them rau hauv lub teeb, thiab scandium thiab sodium foil ntxiv. Thaum lub sij hawm high-voltage tawm, scandium ions thiab sodium ions emit lawv cov yam ntxwv emission wavelengths ntawm lub teeb, feem. Cov kab spectral ntawm sodium yog ob lub npe daj kab, 589.0nm thiab 589.6nm, thaum lub spectral kab yog ib tug series ntawm ze ultraviolet thiab xiav lub teeb emissions los ntawm 361.3-424.7nm. Raws li lawv sib xyaw ua ke, tag nrho cov xim tsim tawm yog lub teeb dawb. Nws yog qhov tseeb vim tias scandium sodium teeb muaj cov yam ntxwv ntawm kev ua haujlwm siab luminous, lub teeb xim zoo, lub zog txuag, lub neej ua haujlwm ntev, thiab muaj zog pos huab tawg muaj peev xwm uas lawv tuaj yeem siv dav rau cov koob yees duab TV, squares, chaw ua si, thiab kev teeb pom kev zoo, thiab yog lub npe hu ua peb tiam lub teeb qhov chaw. Nyob rau hauv Suav teb, hom teeb no yog maj mam nce raws li ib tug tshiab technology, thaum nyob rau hauv qee lub teb chaws tsim, hom teeb no tau dav siv raws li thaum ntxov 1980s.

2. Hnub ci photovoltaic hlwb

Qhov thib ob khawv koob riam phom ntawm scandium yog lub hnub ci photovoltaic hlwb, uas tuaj yeem sau lub teeb tawg rau hauv av thiab tig mus rau hauv hluav taws xob los tsav tib neeg lub neej. Nyob rau hauv hlau insulator semiconductor silicon hnub ci hlwb thiab hnub ci hlwb, nws yog qhov zoo tshaj plaws barrier hlau.

3. γ Radiation qhov chaw

Qhov thib peb khawv koob riam phom ntawm scandium yog hu ua γ Ib qho hluav taws xob, qhov riam phom khawv koob no tuaj yeem ci ntsa iab ntawm nws tus kheej, tab sis lub teeb zoo li no tsis tuaj yeem txais los ntawm qhov muag liab qab, nws yog lub zog photon txaus. Peb feem ntau rho tawm 45 Sc los ntawm cov zaub mov, uas yog tib lub ntuj isotope ntawm scandium. Txhua 45 Sc nucleus muaj 21 protons thiab 24 neutrons. 46Sc, ib qho khoom siv hluav taws xob hluav taws xob isotope, tuaj yeem siv los ua γ Radiation sources lossis tracer atoms kuj tseem siv tau rau kev siv xov tooj cua ntawm cov qog nqaij hlav malignant. Kuj tseem muaj cov ntawv thov xws li scandium garnet lasers, fluorinated iav infrared optical fiber, thiab cathode ray tubes coated nrog scandium hauv TV. Nws zoo nkaus li tias scandium tau yug los nrog lub teeb.

4. Khawv koob seasoning

Cov saum toj no tau hais txog qee qhov kev siv ntawm scandium, tab sis vim nws cov nqi siab thiab cov nqi txiav txim siab, ntau cov khoom siv scandium thiab scandium tsis tshua muaj siv hauv cov khoom lag luam, siv cov txheej nyias nyias zoo li hauv lub teeb. Nyob rau hauv ntau lub teb, Hetong tebchaw yog siv los ua tej yam yees siv seasonings, xws li ntsev, qab zib, los yog monosodium glutamate nyob rau hauv tes ntawm cov kws ua zaub mov. Tsuas yog me ntsis xwb, lawv tuaj yeem ua kom tiav kov.

5. Kev cuam tshuam rau tib neeg

Tam sim no tsis paub meej tias scandium yog qhov tseem ceeb rau tib neeg. Scandium muaj nyob rau hauv cov kab mob hauv tib neeg lub cev. Suspected ntawm carcinogenicity. Scandium yog nquag tsim cov complexes nrog 8-lub teeb pawg, uas tuaj yeem siv rau kev tsom xam ntawm scandium. Neutron radiometric tsom xam tuaj yeem siv los txiav txim qhov ntau hauv qab ng / g.
