ʻO Tantalum (Tantalum) he mea metala me ka helu ʻātoma o 73, a
ʻO ka hōʻailona kemika Ta, kahi helu heheʻe o 2996 °C, kahi helu hoʻolapalapa o 5425 °C,
a me ka mānoanoa o 16.6 g/cm³.ʻO ka mea e pili ana i ka mea
metala hina hina, he kiʻekiʻe loa ka pale ʻana i ka corrosion.ʻAʻole ia
e pane i ka waika hydrochloric, ka waikona nitric concentrated a me ka wai regia no ka mea
ma lalo o ke anu a wela paha.
Aia ka Tantalum i ka tantalite a noho pū me ka niobium.ʻO Tantalum
paʻakikī a ductile, a hiki ke huki ʻia i loko o nā filament lahilahi e hana ai
nā pepa lahilahi.He liʻiliʻi kona coefficient o ka hoʻonui wela.Loaʻa iā Tantalum
nā waiwai kemika maikaʻi a kūpaʻa loa i ka corrosion.Hiki ke
hoʻohana ʻia e hana i nā moku evaporation, etc., a hiki ke hoʻohana ʻia e like me nā electrodes,
nā mea hoʻoponopono, a me nā capacitors electrolytic o nā paipu electron.ʻO ka lāʻau lapaʻau, maʻa ia
e hana i nā lau lahilahi a i ʻole nā kaula no ka hoʻoponopono ʻana i nā ʻiʻo i pohō.ʻOiai ʻo tantalum
kūpaʻa nui i ka corrosion, ʻo kona kūpaʻa ʻana ma muli o ka hoʻokumu ʻana
o kahi kiʻiʻoniʻoni pale paʻa o ka tantalum pentoxide (Ta2O5) ma ka ʻili.
