Tantalum Properties
Astaanta kiimikada Ta, birta cawlan ee birta ah, waxa iska leh kooxda VB ee shaxda xilliyeedka
curiyayaasha, lambarka atomiga 73, atomikada miisaanka 180.9479, kareem kuyuubik jidhka ku salaysan,
Qiimaha guud waa +5.Adkeydka tantalum waa mid hooseeya waxayna la xiriirtaa ogsijiinta
nuxurka.Engegnaanta Vickers ee tantalum caadiga ah waa 140HV oo keliya gudaha
gobolka la tirtiray.Barta dhalaalkeedu waa ilaa 2995°C, iyada oo ku jirta kaalinta shanaad
walxaha elemental ka dib carbon, tungsten, rhenium iyo osmium.Tantalum waa
malleable oo waxaa loo jiidi karaa fiilooyinka khafiifka ah si loo sameeyo foil khafiif ah.Its coefficient of
ballaarinta kulaylku waa yar yahay.Waxa kaliya oo ay ku fidaysaa 6.6 qaybood halkii milyan darajo Celsius.
Intaa waxaa dheer, adaygeedu aad buu u xoog badan yahay, xitaa ka fiican yahay naxaasta.
