(Lab6 Cov KhoomTsim los ntawmWintrustek)

Lanthhanum Hexaboride (Lanthhant buride, lossis Lab66)yog cov inorganic nometallic compound ua los ntawm tsawg-valence boron thiab cov tsis tshua muaj cov hlau keeb lug. Nws yog qhov refractory tej hub uas tuaj yeem muaj sia nyob hnyav thiab nyuaj. Linthhanum Hexaboride Ceramic muaj ntau cov ntawv thov vim nws cov yam ntxwv zoo tshaj, tshuaj lom neeg thiab hluav taws xob.

Nta:

1. Raws li lub tshuab nqus tsev

2. Loj emissivities ntawm electrons

3. Hluav Taws Xob Kev Zoo Uas Zoo
4. Koj yog qhov tseeb rau cov cua sov poob siab
5. Koj ua tau zoo heev rau oxidation thiab tshuaj lom neeg

Lanthhanum Hexaboride Ceramics, nrog lawv lub cev nqaij daim tawv thiab tshuaj lom neeg tshwj xeeb, muaj cov ntawv thov tseem ceeb hauv ntau thaj teb, feem ntau suav nrog cov ntawv thov hauv qab no:

EMITTORON EMISSION DAIM NTAWV: Lanthhanum Hexaboride yog qhov zoo tshaj plaws cov khoom siv hluav taws xob ua haujlwm, cov xeeb ceem ntawm qhov hluav taws xob tsis taus, muaj kev phom sij kub, thiab tshuaj lom neeg zoo. Nws yog feem ntau siv raws li cathode hauv cov phom hluav taws xob rau cov khoom siv hluav taws xob, cov raj hluav taws xob ci, thiab ion imilanters.

Kev kub nyhiab kub thermocouple tiv thaiv cov tubes: Nws cov khoom pov thawj zoo heev kub-ua hauj thiab tshuaj tsis ruaj khov, ua haujlwm ruaj khov rau hauv kev ua haujlwm nyob ruaj khov hauv qhov kub kom txo cov cua sov. Nws tuaj yeem raug siv los ua cov raj tiv thaiv rau cov cua sov kom ntsuas kub kom ntsuas kub hauv qhov chaw kub.

Kev Lag Luam Nuclear: Lanthhanum Hexaboride muaj cov muaj zog nruab nrab lub peev xwm thiab tuaj yeem siv ua Neutron cov khoom siv hauv nuclear reactors los tswj kev siv hluav taws xob nuclear.

Lwm yam lag luam: Nws kuj tseem siv tau los tsim cov khoom tshwj xeeb tshwj xeeb, thiab lwm yam kev ua haujlwm, ua lub luag haujlwm hauv kev lag luam kev ua haujlwm siab lossis ib puag ncig tshwj xeeb.
