Tantalum (Tantalum) ndi chinthu chachitsulo chokhala ndi nambala ya atomiki 73, a
chizindikiro cha mankhwala Ta, malo osungunuka a 2996 ° C, malo otentha a 5425 ° C,
ndi kachulukidwe 16.6 g/cm³. Chinthu chogwirizana ndi chinthucho ndi
chitsulo imvi zitsulo, amene ali mkulu kukana dzimbiri. Sizikutero
zimatani ndi hydrochloric acid, nitric acid ndi aqua regia mosasamala kanthu
pansi pa nyengo yozizira kapena yotentha.
Tantalum imapezeka makamaka mu tantalite ndipo imakhala ndi niobium. Tantalum pa
zolimba kwambiri ndi ductile, ndipo akhoza kukokedwa mu ulusi woonda kupanga
mapepala owonda. Coefficient yake ya kukula kwa kutentha ndi yaying'ono. Tantalum ali ndi zambiri
zabwino mankhwala katundu ndipo kwambiri kugonjetsedwa ndi dzimbiri. Zitha kukhala
amagwiritsidwa ntchito popanga zombo za evaporation, etc., ndipo amathanso kugwiritsidwa ntchito ngati ma electrode,
rectifiers, ndi electrolytic capacitors ma electron machubu. Mankhwala, amagwiritsidwa ntchito
pangani mapepala owonda kapena ulusi kuti mukonze minyewa yomwe yawonongeka. Ngakhale tantalum ndi
kugonjetsedwa kwambiri ndi dzimbiri, kukana kwake kwa dzimbiri ndi chifukwa cha mapangidwe
filimu yotetezeka ya tantalum pentoxide (Ta2O5) pamwamba.
