Chidule chachidule cha tantalum metal element

mtengo wachitsulo wa tungsten

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.
