Čisti metal se može izvući u vrlo fine žice. Na izloženoj površini formira se oksidni film otporan na koroziju. Ne otapa se u kiselinama niti u vodenim otopinama lužina, reagira jedino s fluoridnom kiselinom i rastaljenim alkalijama. Zagrijani metal se zapali na zraku. Inertan je na tjelesne tekućine, pa se rabi za izradu različitih proteza u tijelu.<br /> <br /> Tantal je [[1802.]] godine otkrio [[Anders Ekeberg]] ([[Švedska]]). Ime je dobio po [[Tantal (mitologija)|Tantalu]] iz [[Grčka mitologija|grčke mitologije]] zbog velikih teškoća kod njegovog dobivanja i odvajanja od [[niobij]]a.<br /> <br /> Slitine na bazi tantala su antikorozivne i vrlo čvrste, pa se rabe u svemirskoj tehnologiji te pri izradi kondenzatora i ispravljača.<br /> <br /> {{wječnik-stavka|tantal}}<br /> <br /> ==Izvori==<br /> {{izvori}}<br /> <br /> {{Kemijski elementi}}<br /> {{Mrva-kem-el}}<br /> <br /> [[Kategorija:Kemijski elementi]]</div> WikiSysop
