Khoom Description
Qhov twg yuav tsum muaj kev tiv thaiv corrosion zoo, tantalum yog qhov kev xaiv zoo. Txawm hais tias tsis yog cov hlau tsis zoo, tantalum muaj tshuaj tiv thaiv piv rau cov hlau zoo. Txawm hais tias nws lub cev-centered cubic siv lead ua daim ntawv, tantalum kuj yooj yim heev rau kev ua hauj lwm nrog kub zoo hauv qab chav tsev kub. Vim li no, nws yog ib qho khoom siv hauv ntau yam txheej txheem tshuaj. Piv txwv li, peb tsim cov khoom siv hluav taws xob sib hloov rau cov cuab yeej siv kev lag luam, riveted racks rau kev lag luam cub tawg, cog rau kev lag luam kev kho mob, thiab cov khoom siv hluav taws xob rau kev lag luam hluav taws xob siv peb cov khoom "unyielding".
Tantalum Sheet txheej txheem ntau lawm
High Purity Tantalum Sheet yog yuav luag txhua tus ua siv cov txheej txheem txias. Feem ntau, Tantalum Ingots ntawm 15 ~ 3 0cm yuav txias forged rau hauv slab ntawm 8 ~ 10m thickness, thiab ces yuav txias dov los ntawm xws li slab, compression tus nqi yuav ntau tshaj li 95 feem pua .In industrial manufacturing, ob rau plaub dov mills feem ntau yob cov slabs rau hauv 0.63 mus rau 1.2 cm tuab daim hlau nrog ib tug dav dav ntawm 51 mus rau 102 cm. Txhawm rau kom tsis txhob muaj oxides los ntawm kev txhim kho ntawm qhov chaw, cov txheej txheem dov yog nqa tawm ntawm lossis ze rau chav tsev kub. Vim yog recrystallization, uas hu rau kub dov, qhov kub yuav ncav cuag 1000 degree thiab muaj zog oxidation txheej txheem yuav tshwm sim.
Xyaum txhua daim hlau tantalum tuab yog rhuab rau hauv lub tshuab nqus tsev thaum lub sij hawm annealing txheej txheem.Vim tias tsis muaj theem hloov, tus nqi ntawm cua sov thiab cua txias tsis tseem ceeb. Ntxiv dov siv tus qauv zeb, feem ntau yog ntau yob zeb nrog plaub yob. Vim tias Tantalum hlau yog mos heev, yuav tsum tau ceev faj kom tsis txhob khawb thaum ua thiab thauj.

High Purity Tantalum Sheet nyob rau hauv ntau yam thicknesses thiab qhov ntev yog ib qho tshwj xeeb ntawm Yusheng Hlau. Rau txheej txheej thiab nyias zaj duab xis CVD thiab PVD txheej txheem, suav nrog thermal thiab electron beam (E-Beam) evaporation, tsis tshua muaj kub organic evaporation, atomic txheej deposition (ALD), thiab organometallic thiab tshuaj vapor deposition (MOCVD) rau tej kev siv xws li roj hlwb thiab hnub ci zog, feem ntau ntawm cov nplooj ntawv yog tsim los ntawm ingots. Lub thickness ntau rau tag nrho cov hlau yog 0.04" txog 0.25". Crystallization, khoom lub xeev, thiab lwm yam ultra-siab purity cov tswv yim zoo li sublimation yog siv los tsim cov ntaub ntawv.
Peb tshwj xeeb hauv kev tsim cov khoom sib xyaw tshwj xeeb rau kev lag luam thiab kev tshawb fawb kev kawm nrog rau cov cuab yeej siv thev naus laus zis. Txhua yam hlau tsis tshua muaj hauv ntiaj teb, nrog rau feem ntau ntawm lwm cov ntaub ntawv txiav, tuaj yeem tsim rau hauv cov pas nrig, tuav, lossis daim hlau los ntawm kev casting, nrog rau lwm cov txheej txheem machining, nanoparticles thiab kev daws teeb meem, thiab cov ntaub ntawv organometallic. Ntxiv mus, peb tsim tantalum nyob rau hauv daim ntawv ntawm daim hlau, pas nrig, thiab hmoov. Los ntawm kev thov, cov duab ntxiv muaj.
