Qhov zoo ntawmtantalum rodsfeem ntau yog reflected nyob rau hauv cov nram qab no yam:
High corrosion kuj: Tantalum rods ua tau zoo nyob rau hauv ntau yam corrosive ib puag ncig thiab muaj peev xwm tiv taus corrosion los ntawm muaj zog acids thiab alkalis xws li hydrochloric acid, concentrated nitric acid thiab "aqua regia". Txawm tias nyob rau hauv qhov kub thiab txias, tantalum rods muaj peev xwm tuav tau zoo corrosion kuj, uas ua rau nws tshwj xeeb tshaj yog dav siv nyob rau hauv tshuaj lom neeg kev lag luam.
Kub kub stability: Lub melting point ntawm tantalum rods yog siab li 2996 degree, qhov thib plaub siab tshaj melting point ntawm tag nrho cov hlau. Qhov no ua rau nws ua tau zoo nyob rau hauv qhov kub thiab txias thiab feem ntau yog siv nyob rau hauv high-temperature alloy cov ntaub ntawv nyob rau hauv aerospace thiab nuclear zog industries.
Cov khoom siv zoo: Tantalum rods muaj qhov ntom ntom (16.6g / cm³), zoo plasticity thiab ductility, thiab tuaj yeem ua tiav ntau yam duab, xws li curling thiab ncab. Cov yam ntxwv no ua rau tantalum rods hloov tau yooj yim hauv kev tsim cov khoom siv.
