Tantalum (Tantalum) yog cov khoom siv hlau nrog tus lej atomic ntawm 73, a
Tshuaj cim Ta, lub melting point ntawm 2996 ° C, lub boiling point ntawm 5425 ° C,
thiab qhov ceev ntawm 16.6 g / cm³.Lub ntsiab sib xws rau lub caij yog
steel grey hlau, uas tsis tshua muaj siab corrosion kuj.Tsis yog
react rau hydrochloric acid, concentrated nitric acid thiab aqua regia tsis muaj teeb meem
nyob rau hauv txias los yog kub.
Tantalum feem ntau muaj nyob rau hauv tantalite thiab coexists nrog niobium.Tantalum yog
me ntsis nyuaj thiab ductile, thiab tuaj yeem kos rau hauv nyias filaments los ua
nyias foils.Nws coefficient ntawm thermal expansion yog me me.Tantalum muaj ntau heev
Cov khoom siv tshuaj lom neeg zoo thiab tsis tshua muaj resistant rau corrosion.Nws tuaj yeem yog
siv los ua cov hlab ntsha evaporation, thiab lwm yam, thiab tuaj yeem siv ua electrodes,
rectifiers, thiab electrolytic capacitors ntawm electron raj.Kev kho mob, nws yog siv rau
ua cov ntawv nyias lossis cov xov los kho cov ntaub so ntswg puas.Txawm hais tias tantalum yog
heev resistant rau corrosion, nws corrosion kuj yog vim lub tsim
ntawm qhov ruaj khov tiv thaiv zaj duab xis ntawm tantalum pentoxide (Ta2O5) ntawm qhov chaw.
