Tantalum hmoov

Khoom: hmoov ntawm tantalum hlau, ntom oxide zaj duab xis generated rau saum npoo ntawm cov hmoov muaj unidirectional conductive valve hlau khoom. Cov yeeb yaj kiab anode yog cov tshuaj lom neeg ruaj khov (tshwj xeeb tshaj yog nyob rau hauv cov kua qaub electrolytes), muaj kev tiv thaiv siab (7.5 x 1010 Ω-cm), qhov loj dielectric tsis tu ncua (27.6), thiab me me to tam sim no. Nws kuj muaj qhov zoo ntawm kev ua haujlwm kub ntau (-80 txog 200 degree), kev ntseeg siab, kev poob siab, thiab kev ua haujlwm ntev. Hmoov ntau lawm los ntawm sodium thermal txo thiab hydrogen embrittlement txoj kev. Los yog tantalum hmoov yog tsim nrog molten ntsev electrolyte muaj 55 feem pua ​​KCl - 27.5 feem pua ​​KF - 17.5 feem pua ​​K2TaF7. Nws yog siv los tsim cov khoom siv hluav taws xob zoo electrolytic capacitors (nrog lub peev xwm ntau dua 5 npaug ntau dua li qhov muaj peev xwm ntawm tib qhov loj). Nws yog dav siv hauv cov khoom siv tub rog thiab hauv kev siv tshuab siab. Piv txwv li, missiles, chaw tsheb, TV, electronic computers, thiab lwm yam.

Dab tsi yog tantalum hmoov? Cov yam ntxwv ntawm tantalum

Ta hmoov yog lub xeev hmoov ntawm cov hlau tantalum. Cov cim tshuaj Ta, hlau-grey hlau, yog nyob rau hauv pawg VB nyob rau hauv lub sij hawm lub sij hawm, muaj ib tug atomic naj npawb ntawm 73 thiab ib tug atomic hnyav ntawm 180.9479, thiab yog lub cev-centered cubic crystal nrog ib tug ntau yam tshuaj valence ntawm ntxiv 5. Tantalum muaj ib tug tsawg hardness thiab muaj feem xyuam rau nws cov ntsiab lus oxygen, nrog rau cov ntshiab ntshiab tantalum muaj ib tug Vickers hardness ntawm tsuas yog 140 HV nyob rau hauv lub annealed lub xeev. Nws muaj qhov melting point ntawm 2995 degree thiab nyob rau qib tsib ntawm cov monomers tom qab carbon, tungsten, rhenium, thiab osmium. Tantalum yog ductile thiab tuaj yeem kos rau hauv nyias foils hauv daim ntawv ntawm filaments. Nws coefficient ntawm thermal expansion yog tsawg heev. Nws nthuav tawm los ntawm tsuas yog 6.6 feem ntawm ib lab rau txhua qib Celsius. Nyob rau hauv tas li ntawd, nws yog heev ductile, txawm ntau tshaj li tooj liab.

Nqe:

Tus nqi ntawm tantalum hmoov feem ntau txawv nyob rau hauv purity thiab particle loj, ntxiv rau kev lag luam sib yuav kuj cuam tshuam tus nqi ntawm Ta hmoov. Ib gram ntawm Ta hmoov ntau npaum li cas? Tag nrho raws li hnub tantalum hmoov chaw tsim tshuaj paus hais yuav yeej.

Kev siv:

Qhov ntom ntom oxide zaj duab xis tsim rau ntawm qhov chaw muaj ib txoj kev conductive valve hlau khoom. Cov yeeb yaj kiab anode tsim muaj tshuaj lom neeg ruaj khov (tshwj xeeb tshaj yog nyob rau hauv acidic electrolytes), nrog rau siab resistivity (hauv acidic electrolytes). (tshwj xeeb tshaj yog nyob rau hauv acidic electrolytes), siab resistivity (7.5 x 1010Ω?cm), loj dielectric tas li (27.6), thiab me me to tam sim no. Nws kuj muaj qhov zoo ntawm kev ua haujlwm kub ntau (-80 rau 200 degree), kev ntseeg siab, kev poob siab, kev ua haujlwm ntev, thiab lwm yam. Cov hmoov yog tsim los ntawm sodium thermal txo thiab hydrogen embrittlement txoj kev. Los yog 55 feem pua ​​KCl-27.5 feem pua ​​KF-17.5 feem pua ​​K2TaF7 raws li molten ntsev electrolyte los tsim tantalum hmoov. Nws yog siv los tsim cov khoom siv hluav taws xob zoo electrolytic capacitors (nrog lub peev xwm ntau dua 5 npaug ntau dua li qhov muaj peev xwm ntawm tib qhov loj).

Yusheng Hlau yog ib lub tuam txhab high-tech koom ua ke kev muag khoom, R & D, kev tsim khoom, thiab kev siv cov khoom siv nano. Tam sim no, peb lub Hoobkas tau tsim kev koom tes ntev nrog ntau lub koom haum tshawb fawb tshawb fawb, chav nyob hauv aerospace, thiab ntau lub tuam txhab tsim khoom. Peb cov khoom siv npog cov hmoov tsis tshua muaj hauv ntiaj teb oxide hmoov, hmoov hlau muaj txiaj ntsig, cov hmoov hlau ib leeg, cov hmoov sib xyaw, cov hmoov txhuas, thiab lwm yam. Nrog rau ntau yam khoom, peb tuaj yeem ua tau raws li qhov sib txawv ntawm tus kheej cov khoom xav tau ntawm ntau tus neeg siv khoom hauv kev tshawb fawb thiab kev tsim kho, kev sim thiab kev tsim khoom, kev siv, thiab lwm yam, thiab tau txais kev ntseeg siab ntawm peb cov neeg siv khoom ntau xyoo.
