Tantalum (Tantalum) chinhu chesimbi chine nhamba yeatomu ye73, a
kemikari chiratidzo Ta, nzvimbo yekunyungudika ye2996 °C, nzvimbo yekuvira ye5425 °C,
uye kusimba kwe16.6 g/cm³.Chinhu chinoenderana nechinhu chacho
simbi grey simbi, iyo ine yakanyanya kusimba kusagadzikana.Hazvidaro
kuita kune hydrochloric acid, yakanyura nitric acid uye aqua regia zvisinei
pasi pekutonhora kana kupisa.
Tantalum inonyanya kuwanikwa mu tantalite uye inogarisana ne niobium.Tantalum ndiye
zvine mwero zvakaoma uye ductile, uye inogona kudhonzwa kuita matete filaments kugadzira
mapepa matete.Coefficient yayo yekuwedzera kwekushisa idiki.Tantalum ane zvakawanda
yakanaka makemikari zvivakwa uye inoshingirira zvakanyanya kune ngura.Zvinogona kudaro
inoshandiswa kugadzira evaporation midziyo, nezvimwewo, uye inogonawo kushandiswa semagetsi,
rectifiers, uye electrolytic capacitors emagetsi machubhu.Mukurapa, inoshandiswa
gadzira machira matete kana shinda kugadzirisa manyama akakuvara.Kunyange zvazvo tantalum iri
inopesana zvakanyanya nekuora, kusagadzikana kwayo kunokonzerwa nekuumbwa
yefirimu yakagadzikana yekudzivirira ye tantalum pentoxide (Ta2O5) pamusoro.
