ʻO Tantalum (Tantalum) kahi mea metala me ka helu atomika o 73, a
hōʻailona kemika ʻo Ta, kahi kiko heheʻe o 2996 °C, kahi kiko paila o 5425 °C,
a me ka nui o 16.6 g/cm³. ʻO ka mea e pili ana i ka mea, ʻo ia
metala hina kila, nona ke kūpaʻa kiʻekiʻe loa i ka pala. ʻAʻole ia
pane i ka waikawa hydrochloric, ka waikawa nitric i hoʻopaʻa ʻia a me ka aqua regia me ka nānā ʻole
ma lalo o nā kūlana anu a wela paha.
Loaʻa nui ʻo Tantalum i ka tantalite a noho pū me ka niobium.
paʻakikī iki a ductile, a hiki ke huki ʻia i loko o nā filaments lahilahi e hana
nā pepa kini lahilahi. He liʻiliʻi kona coefficient o ka hoʻonui wela. Loaʻa iā Tantalum
nā waiwai kemika maikaʻi a kūpaʻa loa i ka pala. Hiki ke
hoʻohana ʻia e hana i nā ipu hoʻoheheʻe, a pēlā aku, a hiki ke hoʻohana ʻia e like me nā electrodes,
nā mea hoʻoponopono, a me nā capacitors electrolytic o nā paipu electron. Ma ke ʻano lapaʻau, hoʻohana ʻia ia e
hana i nā pepa lahilahi a i ʻole nā loulou e hoʻoponopono i nā ʻiʻo i hōʻino ʻia. ʻOiai ʻo tantalum
kūpaʻa loa i ka pala, ʻo kona kūpaʻa i ka pala ma muli o ka hoʻokumu ʻia ʻana
o kahi ʻili pale paʻa o ka tantalum pentoxide (Ta2O5) ma luna o ka ʻili.
