Tantalum, lub cim cim Ta, yog qhov tsis tshua muaj, xiav - grey hloov pauv hlau muaj npe nrov rau nws qhov siab melting point (kwv yees li 3017 degree), zoo heev corrosion kuj, thiab zoo ductility. Feem ntau muab rho tawm los ntawm ores zoo li tantalite, nws qhov kev txwv tsis pub tsawg tsis txo qis nws lub luag haujlwm tseem ceeb hauv cov haujlwm xws li hluav taws xob thiab aerospace mus rau cov cuab yeej kho mob thiab kev tsim tshuaj.
Nkag siab Tantalum: Qhov "Precious Hlau" Ncua tseg hauv kev lag luam
Tantalum hlau muaj qhov tshwj xeeb ntawm lub cev thiab tshuaj lom neeg. Raws li cov hlau tsis tshua muaj siab melting point thiab boiling point, nws muaj ib tug ceev ntawm 16.69 g / cm³, surpassed tsuas yog ob peb hlau xws li tungsten thiab rhenium.
Nws cov yam ntxwv tseem ceeb tshaj plaws yog peb zaug: Ua ntej, tshwj xeeb corrosion kuj, muaj peev xwm tiv taus cov acids muaj zog xws li hydrochloric thiab sulfuric acid ntawm chav tsev kub. Thib ob, zoo heev thermal thiab hluav taws xob conductivity, txawm tias me ntsis qis dua tooj liab thiab nyiaj, nws ruaj khov nyob deb tshaj cov hlau zoo tib yam. Thib peb, kev ua haujlwm tau zoo, tso cai rau nws yuav tsum tau dov rau hauv cov ntawv ci tantalum nyias nyias los yog tsim rau hauv complex - zoo li cov khoom.
Electronics Kev Lag Luam: Lub luag haujlwm tseem ceeb ntawmTantalum Capacitor
- Ntawm txhua daim ntawv thov, tantalum muaj kev siv ntau tshaj plaws hauv kev siv hluav taws xob. Tshaj li 70% ntawm lub ntiaj teb tantalum ntau lawm yog siv los tsim tantalum capacitors, uas ua lub luag haujlwm tseem ceeb hauv cov khoom siv hluav taws xob rau lub zog cia, lim, thiab kev tswj hluav taws xob.
- Ntawm ib sab, ib daim duab ntom ntom thiab ruaj khov oxide tuaj yeem tsim rau ntawm qhov chaw ntawm tantalum. Zaj duab xis no ua raws li ob qho tib si rwb thaiv tsev txheej thiab dielectric, muab lub capacitor cov yam ntxwv ntawm "me me thiab loj capacitance"-rau tib lub peev xwm, tantalum capacitor tsuas yog 1/10 qhov loj ntawm txhuas electrolytic capacitor, ua rau nws zoo tagnrho rau cov khoom siv hluav taws xob me me xws li smartphones, laptops, thiab watches.
- Ntawm qhov tod tes, nws muaj kev ruaj ntseg siab heev, ua haujlwm ib txwm nyob rau hauv qhov kub thiab txias ntawm -55℃txog 125 degree, thiab boasts them ceev ceev thiab tso tawm ceev thiab lub neej ntev. Yog li ntawd, nws yog dav siv nyob rau hauv high-end teb xws li cov neeg siv khoom electronics, automotive electronics, thiab aerospace electronics.
Aerospace: Kev ua tau zoo heev nyob rau hauv siab - Ib puag ncig kub
- Lub tshav dav hlau muaj qhov xav tau heev rau cov khoom siv, yuav tsum tau tiv taus qhov kub ntawm ntau txhiab degrees Celsius thiab tiv thaiv kev yaig thiab corrosion los ntawm siab - cua nrawm thaum lub davhlau. Tantalum, nrog nws qhov siab melting point thiab siab zog, tau dhau los ua cov khoom siv zoo tshaj plaws rau daim teb no.
- Tantalum tuav, tantalum tubes, thiab lawv cov alloys (xws li Ta-10W) yog siv los tsim cov combustion chamber liners, foob pob ua ntxaij cav nozzles, siab -cov khoom kub ntawm turbine blades, heat exchangers, thiab thermal tiv thaiv txheej rau satellites, withstanding high - kub thiab corrosive ib puag ncig. Lub caij no, tantalum alloys muaj siab dua - qhov kub thiab txias dua li cov nickel-based superalloys, txhim kho lub cav thrust thiab efficiency, thiab ua kom lub foob pob hluav taws cov kev tiv thaiv thermal thaum lub sij hawm atmospheric reentry. Tantalum kuj tseem txhim khu kev ruaj ntseg ntawm cov cuab yeej txiav rau machining aerospace cov ntaub ntawv. Txawm hais tias nws tus nqi siab dua, tantalum txo cov kev xav tau ntawm kev saib xyuas thiab txhim kho kev nyab xeeb thiab kev ua haujlwm ntawm lub davhlau.
Kev Kho Mob Field: Qhov Kev Xaiv Zoo Tshaj Plaws rau Biocompatibility.
Tantalum tsis ua rau lub cev tsis muaj zog tiv thaiv kab mob hauv tib neeg lub cev, thiab nws tsis yog corroded los ntawm tib neeg cov ntaub so ntswg, ua rau nws daim ntawv thov nyob rau hauv kev kho mob ntau zuj zus, tau txais nws lub npe ntawm "biometal."
- Hauv orthopedics, tantalum feem ntau yog siv los tsim cov khoom cog xws li cov pob qij txha, pob txha taub hau, thiab pob txha daim hlau. Piv nrog rau cov tsoos titanium alloys, tantalum's elastic modulus yog ze rau ntawm tib neeg cov pob txha, thiab nws cov qauv ntxeem tau tso cai rau cov pob txha ingrowth, ua rau nws tsim nyog rau kev kho mob femoral taub hau necrosis lossis txha caj qaum fusion phais. Piv txwv li, rau cov neeg mob uas muaj pob txha loj heev, cov kws kho mob siv cov ntswj tantalum rods rau implantation los txhawb cov pob txha regeneration.
- Hauv kev kho hniav, tantalum yog siv los tsim cov hniav cog hniav. Nws corrosion-cov khoom tiv thaiv tiv thaiv kev yaig los ntawm cov qaub ncaug thiab cov khoom khib nyiab hauv lub qhov ncauj, thiab nws muaj biocompatibility zoo nrog cov pos hniav, txo qhov yuav ua rau mob.
- Tantalum kuj tseem siv los tsim cov electrode ua rau lub plawv pacemakers. Nws cov conductivity thiab biostability ua kom lub sijhawm ntev -kev ua haujlwm ruaj khov ntawm cov pacemakers, tiv thaiv kev noj qab haus huv thiab lub neej ntawm cov neeg mob plawv.
