Khoom thiab kev siv ntawm tantalum hlau

Nyob rau hauv qhov xwm txheej, tantalum ores tau tawg thiab feem ntau cuam tshuam nrog niobium, uas nyuaj rau kev sib cais. Yog li ntawd, nws tsis yog txog xyoo 1903 uas tantalum hlau tau ua kom zoo, thiab kev tsim khoom lag luam pib xyoo 1922.

Tantalum yog cov hlau grey-dawb, tawv heev, thiab kub heev. Raws li cov lus hais tias, "Qhov kub tiag tiag tsis ntshai hluav taws." Qhov tseeb, lub melting point ntawm kub tsuas yog 1063 degree C, thaum lub melting point ntawm tantalum hlau yog siab li 2996 degree C, yog li tantalum tuaj yeem hu ua "fiery vajra".

Tantalum hlau yog tus cwj pwm los ntawm kev tiv thaiv corrosion, nws tsis ntshai ntawm nitric acid, sulfuric acid, thiab txawm nyob rau hauv aqua regia tsis yaj. Tib yam uas tuaj yeem ua rau hlau tantalum corrosion yog hydrofluoric acid. Tantalum cov tshuaj stability tau dhau lub iav, ceramics, tuaj yeem piv nrog Tin, tab sis tus nqi ntawm tantalum hlau tsuas yog ib feem xya ntawm Tin. Yog li ntawd, tib neeg feem ntau siv tantalum hlau es tsis txhob uranium los ua electrodes, crucibles, evaporation lauj kaub tais diav, hlau lim ntaub, nrog rau cov tshuaj ntau lawm nrog lub reactor, cov tshuaj tiv thaiv tso tsheb hlau luam, tshuaj tiv thaiv yees thiab pipelines, li qub, thiab lwm yam., tab sis kuj siv cov tshuaj reactor. tantalum hlau los tsim cov khoom hnyav, nibs, spinnerets, watches, xob laim thiab cov hniav nyiaj hniav kub thiab lwm yam.

Tantalum hlau kuj tuaj yeem nyob ze rau tib neeg lossis tsiaj hlwb, yog li nws muaj lub koob npe nrov ntawm "pro-biotic hlau". Piv txwv li, tantalum daim hlau tuaj yeem siv los kaw cov pob txha taub hau ntawm tib neeg lub taub hau, thiab tantalum strips tuaj yeem hloov cov pob txha tawg los txhawb tib neeg lub cev. Thiab tom qab ib lub sijhawm, tib neeg cov leeg tuaj yeem loj hlob ntawm tantalum daim hlau thiab strips. Nws tau hais tias tom qab tus neeg lub pob ntseg sab nrauv puas lawm, ib daim ntawv nyias ntawm tantalum tuaj yeem siv los ua pob ntseg pob ntseg thiab tom qab ntawd cog rau ntawm daim tawv nqaij. Kho pob ntseg yuav luag zoo ib yam li pob ntseg tiag; Nws tseem tuaj yeem rub mus rau hauv cov hlau tantalum, cog rau hauv cov leeg los kho cov leeg puas thiab cov paj hlwb, thiab lwm yam.

Tantalum muaj ntau yam kev siv. Yuav kom txuag tau tus nqi ntawm tantalum, tib neeg tau sim ua kom tiav tantalum plating kev kho mob ntawm lwm yam hlau, thiab cov txiaj ntsig tau ua tsis tiav. Tsis ntev los no, xov xwm zoo tuaj hais tias cov kws tshawb fawb Lavxias tau kov yeej qhov teeb meem ntawm tantalum plating. Tantalum plating yog hais tias yuav tsum tau kub ntawm 700 degree thiab yuav tsum tau nqa tawm nyob rau hauv tsis muaj dej thiab huab cua. Peb ntseeg tias qhov kev siv tshuab no yuav ua rau muaj kev siv dav dua ntawm tantalum.
