Tantalum (Tantalum) chinhu chesimbi chine nhamba yemaatomu makumi manomwe nematatu, a
chiratidzo chemakemikari Ta, poindi yekunyunguduka ye2996 °C, poindi yekufashaira ye5425 °C,
uye huwandu hwe16.6 g/cm³. Chinhu chinoenderana nechinhu ichi ndeche
simbi yegrey, iyo inodzivirira ngura zvakanyanya. Haiite
kuita kune hydrochloric acid, nitric acid yakanyanyisa uye aqua regia zvisinei nekuti
mumamiriro ekunze anotonhora kana kupisa.
Tantalum inonyanya kuwanikwa mutantalite uye inogara pamwe chete neniobium.
dzakaoma zvine mwero uye dzakapfava, uye dzinogona kukweverwa kuita tambo dzakatetepa kuti dzigadzirwe
mafoil matete. Kuwanda kwekuwedzera kwekupisa kwayo kudiki. Tantalum ine zvakawanda
ine hunhu hwakanaka hwemakemikari uye inodzivirira ngura zvakanyanya.
inoshandiswa kugadzira midziyo yekufema, nezvimwewo, uye inogonawo kushandiswa semaerekitirodhi,
zvinogadzirisa, uye ma electrolytic capacitors emachubhu e electron. Mukurapa, inoshandiswa
gadzira machira matete kana shinda dzekugadzirisa matishu akakuvara. Kunyangwe zvazvo tantalum iri
inodzivirira zvikuru ngura, kuramba kwayo ngura kunokonzerwa nekuumbwa kwayo
yefirimu rekudzivirira rakasimba retantalum pentoxide (Ta2O5) pamusoro.
