Khoom yam ntxwv
Ntshiab tantalum ntawv ci yog cov khoom siv siab -cov khoom siv refractory hlau nyias. Nws yog tsim los ntawm siab -purity tantalum hlau nrog ib tug purity ntawm 99.95% los ntawm txias dov ua. Tantalum muaj qhov ceev ntawm 16.6 g / cm³, nws cov ntsiab lus melting nce mus txog 2996 degree, uas nyob qib siab ntawm tag nrho cov hlau, thiab nws cov tshuaj inertness yog qhov ruaj khov. Thaum tantalum tau ua tiav rau hauv daim ntawv foil, nws lub cev thiab tshuaj lom neeg muaj peev xwm khaws cia thiab nthuav tawm hauv daim ntawv ntawm cov ntawv hloov pauv. Nws yog ib yam khoom tseem ceeb uas yuav tsum tau muaj nyob rau hauv ntau yam txuj ci tseem ceeb.
Los ntawm cov ntaub ntawv kev tshawb fawb pom, qhov tseem ceeb ntawm kev sib tw ntawm cov ntawv ci ntshiab tantalum los ntawm tantalum pentoxide passivation zaj duab xis spontaneously tsim ntawm nws qhov chaw. Lub thickness ntawm no oxide txheej yog hais txog 2-5 nm, nrog ib tug ntom qauv thiab tseem ceeb muaj peev xwm kho tus kheej. Thaum cov ntawv ci nto yog khawb los yog ib feem puas, tsuav yog muaj cov pa oxygen nyob rau hauv ib puag ncig, cov yeeb yaj kiab passivation tuaj yeem rov tsim dua sai thiab rov ua nws txoj haujlwm tsis zoo. Cov yam ntxwv no ua rau cov ntawv ci ntshiab tantalum tuaj yeem pom kev ruaj ntseg tsis sib haum los ntawm lwm cov ntaub ntawv hlau hauv cov xov xwm corrosive heev. Nyob rau theem electrochemical, txawm hais tias tus qauv electrode muaj peev xwm ntawm tantalum yog -0.81 V ( txheeb ze rau tus qauv hydrogen electrode), lub neej ntawm cov zaj duab xis passivation tsub kom lub peev xwm tiag tiag rau +0.5 rau +1.0 V. Cov khoom siv tag nrho yog nyob rau hauv cheeb tsam electrochemical passivation, thiab yuav luag tsis muaj anodic dissolution tshwm sim.
Qhov dav dav purity ntawm kev lag luam- qib ntshiab tantalum tuaj yeem ncav cuag 99.95%, thiab siab -purity tantalum kuj tuaj yeem ncav cuag 99.99%. Cov ntsiab lus impurity xws li oxygen, carbon, nitrogen, hlau, npib tsib xee, thiab lwm yam yog nruj me ntsis txwv rau qib qis heev. Qhov tseem ceeb ntawm kev purity siab tsis yog tsuas yog txhim kho cov kev ua tau zoo ntawm cov khoom, tab sis kuj yuav tshem tawm qhov kev pheej hmoo ntawm kev ua tsis tiav uas yuav tshwm sim los ntawm cov kab tsis huv ntawm cov khoom siv tshuaj lom neeg, piv txwv li, hauv cov tshuaj reactors, txawm tias cov hlau ions leaching tawm tuaj yeem paug cov khoom lag luam; Nyob rau hauv tib neeg implants, nag lossis daus ntawm tej yam teeb meem yuav ua rau lom rejection tshwm sim.
Tsis tas li ntawd, tantalum hlau kuj muaj ductility thiab workability. Ntshiab tantalum ntawv ci muaj qhov elongation ntawm ntau tshaj 25% nyob rau hauv lub xeev annealed thiab yuav stamped, khoov, sib sib zog nqus nqus, los yog dov rau hauv complex geometric duab yam tsis muaj cracking. Cov yam ntxwv no tso cai rau nws hloov pauv mus rau ntau yam kev xav tau ntawm kev lag luam, los ntawm ultra-thin capacitor winding mus rau hauv ob sab phlu kev tsim kho cov cuab yeej nkhaus, thiab tuaj yeem ua tiav qhov haum.

Kev tswj xyuas qhov system nruj thiab traceability
Txhua pawg ntawm cov ntawv ci ntshiab tantalum peb muab tau ua tiav cov txheej txheem tswj kev ua tau zoo, suav nrog tshuaj lom neeg muaj pes tsawg leeg spectral tsom xam, roj impurity cov ntsiab lus tshawb pom (oxygen, nitrogen, carbon, hydrogen), cov cuab yeej ntsuas thiab ntsuas qhov tseeb. Cov khoom lag luam tuaj yeem muab cov ntawv pov thawj zoo uas ua raws li ASTM B708 los yog GB / T cov qauv kom ntseeg tau cov khoom siv tau zoo, kev ua haujlwm ruaj khov, thiab zoo sib xws ntawm cov khoom siv. Rau cov ntawv thov tshwj xeeb, peb tseem tuaj yeem muab cov ntaub ntawv xeem thib peb ntawm - tog neeg kom ua tau raws li qhov yuav tsum tau muaj ntawv pov thawj nruj me ntsis hauv aerospace, kho mob cog thiab lwm yam haujlwm.
Cov khoom siv
Qhov no yog qhov tseem ceeb daim ntawv thov kev taw qhia ntawm ntshiab tantalum ntawv ci nrog cov kev zoo tshaj plaws. Hauv cov khoom siv tshuaj lom neeg uas yuav tsum tau ua kom muaj kev tawm tsam hnyav heev - xws li hydrochloric acid concentration towers, sulfuric acid heat exchangers, nitric acid reactors, chlor-alkali industrial equipment, etc. - siv cov ntshiab tantalum ntawv ci li hauv ob sab phlu los yog cladding yog ib qho kev daws teeb meem kom ua tiav kev ua haujlwm ntev -. Cov ntaub ntawv tshwj xeeb qhia tau hais tias nyob rau hauv cov xwm txheej ntawm hydrochloric acid nrog qhov concentration tsawg dua lossis sib npaug li 37% thiab qhov kub ntawm Less dua lossis sib npaug li 190 degree, qhov corrosion ntawm tantalum tsawg dua 0.01 hli / xyoo; Nws kuj tseem tiv taus sulfuric acid nrog qhov concentration tsawg dua lossis sib npaug li 98% thiab qhov kub thiab txias tsawg dua lossis sib npaug li 200 degree; nyob rau hauv nitric acid nyob rau hauv tag nrho cov concentration ntau (nrog rau lub xeev boiling), tantalum qhia tag nrho corrosion kuj. Tantalum tseem tuaj yeem ua haujlwm ruaj khov rau cov xov xwm corrosive heev xws li aqua regia, chlorine, thiab bromine. Tsis tas li ntawd, tantalum kuj muaj kev tiv thaiv zoo heev rau cov organic acids (xws li acetic acid, citric acid), chloride molten ntsev, thiab kua hlau. Los ntawm cov ntaub ntawv ntshiab tantalum rau ntawm cov pa roj carbon steel los yog lwm cov substrates, cov cuab yeej tuaj yeem ua kom muaj zog thiab tsis muaj tshuaj lom neeg, ua kom nws lub neej ua haujlwm ntev.
Lub melting point ntawm tantalum yog siab li 2996 degree, nyob rau hauv qeb siab ntawm tag nrho cov hlau. Nyob rau hauv siab -qhov kub thiab txias nyob rau hauv lub tshuab nqus tsev los yog inert cua, ntshiab tantalum ntawv ci yog dav siv raws li multi- txheej tshav kub shields, cua sov khoom txhawb nqa, ntim ntim (nkoj, tais) thiab raws li ib tug tiv thaiv txheej rau siab - kub sensors. Hauv cov ntawv thov no, cov ntawv ci ntshiab tantalum muaj peev xwm tiv taus rov qab thermal cycling hauv 1500℃txog 2500℃ntau yam, tswj cov khoom siv kho tshuab thiab cov duab ruaj khov. Piv txwv li, nyob rau hauv sapphire siv lead ua kev loj hlob rauv, siab - kub ceramic sintering rauv, tshwj xeeb alloy nqus smelting thiab sib nqus khoom sintering khoom, thermal rwb thaiv tsev tshuab ua los ntawm tantalum ntawv ci tuaj yeem txo qhov kub poob thiab txhim kho qhov sib xws thiab kev tswj ntawm qhov cub kub.
Tantalum yog lub npe hu ua "biophilic hlau" thiab muaj keeb kwm kev kho mob ntau tshaj 80 xyoo txij li thaum nws yog thawj zaug siv nyob rau hauv orthopedics nyob rau hauv 1940. Ntshiab tantalum foil yog siv los tsim pob txha taub hau kho meshes, orthopedic implants (pob txha daim hlau, pob txha rau tes), pacemaker casings, cardiovascular kho mob. Nws cov txiaj ntsig tseem ceeb yog: nws yog inert kiag li thiab tsis ua rau lub cev tsis muaj zog lossis ua xua; nws tuaj yeem muaj qhov zoo osseointegration nrog cov pob txha nyob; thiab nws tsis yog- sib nqus kiag li, yog li cov neeg mob implanted tuaj yeem ua qhov kev kuaj MRI yam tsis muaj khoom cuav lossis hloov chaw.
Hauv kev lag luam ntawm microelectronics, ntshiab tantalum ntawv ci yog siv los ua cov khoom siv hauv paus ntawm sputtering lub hom phiaj rau kev tso cov tantalum los yog tantalum nitride films ntawm daim tawv nqaij raws li diffusion barriers rau tooj liab interconnect xov hlau. Tsis tas li ntawd, ultra-nyias siab-purity tantalum ntawv tseem yog cov khoom tseem ceeb anode rau siab-kawg tantalum capacitors. Los ntawm kev nthuav dav thaj chaw tshwj xeeb los ntawm electrochemical etching, siab capacitance ib chav tsev ntim tuaj yeem ua tiav. Hauv cov khoom siv hluav taws xob hauv aerospace, tub rog radar thiab kev sib txuas lus, tantalum foil capacitors paub txog lawv txoj kev ntseeg siab.
