Samarium yog lub ntiaj teb tsis tshua muaj av uas yog lub suab paj nruag-dawb, mos, thiab cov hlau. Nws muaj lub ntsiab lus melting ntawm 1074 ° C (1976 ° F) thiab lub qhov cub npau npau ntawm 1794 ° C (3263 ° F). Samarium yog lub npe hu rau nws lub peev xwm los nqus neutrons thiab rau nws siv nyob rau hauv kev tsim cov ntawv thov, uas tau siv ntau cov ntawv thov, suav nrog hauv ntau lub cev thiab cov tshuab hluav taws xob.
Samarium Hlau feem ntau yog tsim los ntawm ntau txoj kev, suav nrog cov electrolysis thiab kev txo cov thermal. Nws yog feem ntau muag nyob rau hauv daim ntawv ntawm ingots, cov ntawv, lossis hmoov, thiab tseem yuav tau ua rau lwm cov ntaub ntawv los ntawm kev ua yeeb yam xws li kev ua yeeb yam lossis forging.
Samarium Hlau muaj ntau daim ntawv thov muaj peev xwm, suav nrog hauv kev tsim cov catalysts, alloys, thiab cov khoom hluav taws xob, thiab lwm cov ntaub ntawv tshwj xeeb. Nws tseem siv rau kev tsim cov roj nuclear cov roj thiab hauv kev tsim cov tsom iav tshwj xeeb thiab ceramics.

Daim ntawv thov

Cov hlau nplaum tas mus li: Ib qho ntawm cov ntawv thov tseem ceeb tshaj plaws ntawm Samarium yog cov khoom siv ntawm Samarium cobalt (SMCO) Hlau nplaum. Cov hlau nplaum tas mus li no tau paub txog lawv lub zog ua kom muaj zog thiab ua rau lawv zoo tshaj plaws rau kev siv cov kev ua haujlwm zoo xws li cov neeg tsav tsheb muaj zog, cov tshuab hluav taws xob, thiab cov ntsuas thiab sensors. SMCO cov hlau nplaum yog qhov tshwj xeeb tshaj plaws hauv Aerospace thiab kev tiv thaiv kev lag luam, qhov kev ntseeg tau thiab kev ua tau zoo.
Nuclear Reactors: Samarium yog siv los ua Neutron Absorber hauv cov tshuaj tua hluav taws xob nuclear. Nws muaj peev xwm ntes cov neutrons, yog li pab tswj cov txheej txheem kev ua haujlwm thiab tswj hwm qhov ruaj khov ntawm tus reactor. Samarium feem ntau koom rau hauv kev tswj cov pas nrig thiab lwm yam, ua haujlwm rau kev nyab xeeb thiab kev lag luam muaj txiaj ntsig ntawm cov nroj tsuag hluav taws xob nuclear.
Phosphors thiab Teeb Pom Kev Zoo: Samarium sib txuas yog siv hauv phosphors rau cov ntawv thov teeb pom kev zoo, tshwj xeeb tshaj yog cov hlua hluav taws xob (CRTS) thiab cov fluorescent teeb. Sojarium-doped cov ntaub ntawv tuaj yeem tawm lub teeb ntawm cov wavelengths, Li txhim kho cov xim zoo thiab ua tau zoo ntawm cov teeb pom kev zoo. Daim ntawv thov no yog qhov tseem ceeb rau kev txhim kho cov kev qhia thev naus laus zis thiab lub zog ua hluav taws xob kom zoo.
Alloying Tus Neeg Sawv Cev: Ntshiab samarium yog siv los ua ib qho kev ua kom zoo tshaj plaws hauv ntau cov hlau loj, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov hlau nplaum tsis tshua muaj hlau thiab lwm cov khoom siv siab. Qhov kev sib ntxiv ntawm cov khoom siv tshuab cov tshuab thiab cov corrosion tsis kam ntawm cov alloys, ua rau lawv haum rau siv cov khoom siv hluav taws xob, kev lag luam lag luam thiab aerospace.
