Dab tsi yog kev siv ntawmtantalum rods?
Tantalum yog ib tug silvery, lustrous, mos thiab ntshiab hlau. Cov hlau no yog cov hlau uas muaj zog, cov hlau uas tsis muaj zog rau cov tshuaj tua kab mob ntawm qhov kub hauv qab 150 degree lossis 302 degree F.
Tantalum yog tsim los ntawm cov minerals tantalite, columbite thiab columbite.
Cov tshuaj tantalum yog cim los ntawm Ta.
Nws belongs rau pawg 5 ntawm lub sij hawm ntawm lub ntsiab lus, nrog rau lub sij hawm tus naj npawb ntawm 6 thiab ib tug atomic tooj ntawm 73.
Vim tias tantalum muaj oxides ntawm nws qhov chaw, nws kuj yog corrosion-resistant.
Txawm hais tias tantalum tuaj yeem ua kom cov ductility, lub zog thiab melting point ntawm cov hlau, lub caij no tsis tshua siv los ua tus neeg sawv cev alloying vim tias nws rhuav tshem cov hlau uas tsis yog hlau.
