Lub cev thiab tshuaj muaj zog:
Chemical symbol Ta, steel grey metal, belongs to VB group in the periodic table, atomic number 73, atomic weight 180.9479, body-centered cubic crystal, common valence yog +5. Tantalum muaj ib tug tsawg hardness thiab muaj feem xyuam rau cov ntsiab lus oxygen. Ordinary ntshiab tantalum muaj Vickers hardness ntawm tsuas yog 140HV nyob rau hauv lub xeev annealed. Nws cov ntsiab lus melting yog siab li 2995 degree, qeb thib tsib ntawm tib yam khoom, thib ob tsuas yog carbon, tungsten, rhenium thiab osmium. Tantalum yog ductile thiab tuaj yeem kos rau hauv nyias foils. Nws thermal expansion coefficient tsawg heev. Nws tsuas yog nthuav tawm los ntawm 6.6 qhov chaw ib lab rau txhua qhov kev nce qib Celsius. Tsis tas li ntawd, nws muaj zog toughness, uas yog zoo dua tooj liab.
