Sumo pfupi ye tantalum metal element

tungsten simbi mutengo

Tantalum (Tantalum) chinhu chesimbi chine nhamba yeatomu ye73, a

kemikari chiratidzo Ta, nzvimbo yekunyungudika ye2996 °C, nzvimbo yekuvira ye5425 °C,

uye density ye16.6 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 inogona 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.
