Raws li peb txhua tus paub, ib qho ntawm lub hom phiaj qhov tseem ceeb ntawm kev ua tau zoo yog purity. Cov kev cai purity ntawm lub hom phiaj txawv ntawm cov kev siv tau zoo.Kev siv cov khoom siv purity titanium lub hom phiaj yog kim dua thiab muaj lub qhov rais me me dua li cov kev lag luam ntshiab titanium.utilized feem ntau kom haum cov kev xav tau ntawm ob peb qhov tshwj xeeb sectors.Dab tsi ces yog Qhov tseem ceeb siv rau high-purity titanium lub hom phiaj?
High-purity titanium lub hom phiaj feem ntau yog siv rau:
1. Cov khoom siv roj ntsha
Txij li thaum titanium tsis yog hlau nplaum, lub zog hlau nplaum yuav tsis ua rau nws ua hlau nplaum. Nws ua haujlwm zoo nrog tib neeg lub cev thiab tsis muaj kev phiv tsis zoo. Nws tuaj yeem siv los tsim kev cog qoob loo rau tib neeg lub cev.Txawm li cas los xij, muab qhov kev sib cais ntawm impurities hauv titanium, purity ntawm titanium rau cog yuav tsum siab npaum li qhov ua tau zoo. Feem ntau, cov ntaub ntawv kho mob titanium tsis ncav cuag qib siab purity titanium.Biological strapping tuaj yeem ua los ntawm high-purity titanium hlau.Lub catheter-embedded titanium txhaj koob tau zoo ib yam li qib high-purity titanium.
2. Cov khoom siv kho kom zoo nkauj
High-purity titanium tuav nws cov xim qub qub txawm tias tom qab txuas ntxiv mus rau qhov chaw ua tsaug rau nws qhov kev tiv thaiv siab rau atmospheric corrosion.Vim li ntawd, cov ntaub ntawv rau kev tsim vaj tsev kuj tuaj yeem ua los ntawm high-purity titanium.Ntxiv, nyob rau hauv xyoo tas los no, titanium. tau siv los ua ntau yam khoom siv thiab cov ris tsho, nrog rau cov hlua tes, watches, thiab tsom iav tsom iav. Titanium yog siv vim nws yog resistant rau corrosion, tsis hloov xim, yuav khaws tau ib tug zoo sheen rau lub sij hawm ntev heev, thiab tsis irritate tib neeg cov tawv nqaij thaum nws los rau hauv kov nrog nws.The theem ntawm 5N purity rau lub titanium siv nyob rau hauv ib co embellishments tau tiav.
3. Cov khoom sib sau ua ke
Titanium yog ib qho tshwj xeeb reactive hlau nrog cov yam ntxwv tshuaj uas tso cai rau nws cuam tshuam nrog ntau yam ntawm cov khoom ntawm qhov kub thiab txias. Muaj zog active gas adsorption tshwm sim nyob rau saum npoo ntawm high-purity titanium, xws li O2, N2, CO, CO2, thiab dej vapor. tshaj 650 degree. Ntawm phab ntsa twj tso kua mis, Ti zaj duab xis uas evaporated tuaj yeem tsim qhov chaw nrog lub peev xwm adsorption siab. Vim yog cov yam ntxwv no, Ti tau nquag siv los ua tus getter hauv cov tshuab rau kev siv lub tshuab nqus tsev siab heev.Qhov kev ua haujlwm siab kawg ntawm lub twj tso kua mis sputtering ion tuaj yeem qis li 10-9Pa thaum siv hauv cov twj sublimation, sputtering ion twj, lwm.
4. Cov ntaub ntawv xov xwm hauv hluav taws xob
Kev siv cov purity titanium nyob rau hauv sputtering lub hom phiaj, integrated circuits, DRAMs, thiab cov vaj huam sib luag vaj huam sib luag tau nthuav dav tsis ntev los no los ntawm kev lag luam high-tech 'kev nthuav dav sai hauv cov cheeb tsam xws li semiconductor technology thiab cov ntaub ntawv thev naus laus zis. Tsiv mus rau pem hauv ntej.As diffusion barriers thiab thaiv cov ntaub ntawv rau kev tswj electrodes nyob rau hauv semiconductor VLSI kev lag luam, titanium silicon tebchaw, titanium nitrogen tebchaw, tungsten titanium tebchaw, thiab lwm yam.Cov ntaub ntawv no yog tsim los siv cov txheej txheem sputtering, uas hu rau lub hom phiaj titanium nrog siab. degree ntawm purity, tshwj xeeb tshaj yog rau radioactive thiab alkali hlau ntsiab.
Tsis ntev los no, high-purity titanium uas phim lub purity ntawm lub hom phiaj titanium siv nyob rau hauv cov txheej txheem sputtering kuj tau pib siv.Titanium purity tam sim no yuav tsum muaj tsawg kawg yog 4N5 (99.995%) lossis 5N (99.999%) rau 4 Mbit VLSI, thaum nws xav tau tsawg kawg yog 6N (99.9999%) rau 16 Mbit thib peb-tiam VLSI.
