Tantalum muaj cov tshuaj zoo heev thiab tiv taus corrosion heev. Ob leeg nyob rau hauv txias thiab kub, hydrochloric acid, concentrated nitric acid thiab "aqua regia" tsis reactive. Tantalum rau hauv 200 degree sulfuric acid immersion rau ib xyoos, txheej txheej ntawm tsuas yog 0.006 hli kev puas tsuaj. tungsten phaj, molybdenum phaj, tungsten qws, molybdenum pas nrig, tungsten raj, molybdenum raj, tungsten crucible, molybdenum crucible thwmsim tau ua pov thawj tias tantalum pas nrig hauv qhov qub, alkali tov, chlorine, bromine, ntau lwm yam sulfuric acid tsis yog sulfuric acid. zoo, tsuas yog nyob rau hauv lub luag hauj lwm ntawm hydrofluoric acid thiab kub concentrated sulfuric acid cov tshuaj tiv thaiv. Xws li qhov xwm txheej no kuj tsis tshua muaj ntawm cov hlau.
Tantalum muaj ntau yam kev siv vim nws cov khoom. Hauv kev npaj ntau yam khoom siv inorganic acid, tantalum tuaj yeem siv los hloov cov hlau tsis muaj steel, lub neej ntau dua stainless hlau kaum ob zaug. Tsis tas li ntawd, hauv kev lag luam tshuaj lom neeg, hluav taws xob, hluav taws xob thiab lwm yam lag luam, tantalum tuaj yeem hloov cov dej num uas yuav tsum tau ua los ntawm cov hlau zoo nkauj platinum yav dhau los, kom tus nqi yuav tsum tau txo qis heev.
Tsis tas li ntawd, tantalum tseem refining super-muaj zog hlau, corrosion-resistant steel thiab kub-resistant steel alloys ntawm cov ntsiab lus tseem ceeb, muaj peev xwm muab kev loj hlob ntawm rockets, spaceships, dav hlau dav hlau thiab lwm qhov chaw technology tsim nyog rau cov ntaub ntawv tshwj xeeb. Cov hlau tsis sib nqus ua los ntawm tantalum thiab tungsten tau siv dav hauv kev lag luam hluav taws xob, tshwj xeeb tshaj yog tantalum carbide tsim los ntawm tantalum thiab carbon, uas muaj qhov nyuaj heev, txawm tias nyob rau hauv cov xwm txheej siab thiab auriferous hlau. tungsten phaj, molybdenum phaj, tungsten pas nrig, molybdenum pas nrig, tungsten raj, molybdenum raj, tungsten crucible, molybdenum crucible tig cov cuab yeej ua los ntawm nws tuaj yeem txiav ntau cov alloys nyuaj ntawm kev kub ceev; Txhua yam kev xyaum ua los ntawm nws tuaj yeem hloov tau rau cov alloys nyuaj tshaj plaws los yog chrysolite. Yog li ntawd, tantalum kuj tseem suav tias yog "vitamin" hauv smelting.
