Qhov tsawg tshaj plaws thiab muaj txiaj ntsig tshaj plaws ntawm tag nrho cov ntaub ntawv tsis yog kub lossis platinum raws li koj xav, tab sis cov hlau koj tsis tau hnov txog: tantalum. Thiab rau qhov laj thawj zoo. Tantalum yog qhov tsis tshua muaj kev ruaj khov nyob hauv peb lub hnub ci tag nrho, tsuas muaj ib qho tantalum atom rau txhua 181 billion atoms ntawm lwm cov ntsiab lus. Qhov no ua rau tantalum tsis tshua muaj ntau dua li kub lossis tej yam hlau muaj nuj nqis. Sib nrug los ntawm nws qhov tsis tshua muaj, tantalum muaj cov txiaj ntsig zoo uas tau teeb tsa saum toj no tag nrho lwm cov hlau hauv watchmaking thiab hniav nyiaj hniav kub. Tej zaum qhov tseem ceeb tshaj plaws ntawm cov no yog qhov ua tau zoo kawg ntawm tantalum nyob rau hauv nws cov ntshiab, unalloyed xeev.
Tantalum tsis xav tau qhov kev txhawb nqa metallurgical no rau cov ntsiab lus tsis muaj zog. Hauv daim ntawv ntshiab, nws khav theeb Vickers hardness ntawm 200 thiab lub zog tensile ntawm 900 MPa, ua rau nws nyuaj npaum li thiab yuav luag ob npaug li qhov zoo tshaj plaws steels. Tsis tas li ntawd, tantalum yog zoo tiv thaiv txhua yam ntawm corrosion. Txawm hais tias peb hu 316L "stainless steel", qhov no alloy yog raug rau pitting thiab crevice corrosion nyob rau hauv chlorinated dej thiab nto corrosion nyob rau hauv dej ntsev. Tantalum luag tawm ntawm qhov tsis muaj zog corrosion, vim tias cov tshuaj hnyav thiab cov kua qaub muaj zog tsis cuam tshuam rau nws. Txawm tias aqua regia, tus huab tais ntawm tag nrho cov acids (aka "aqua regia", lub npe los ntawm alchemists rau nws lub peev xwm los yaj cov khoom muaj txiaj ntsig zoo li kub) tsis tuaj yeem tua lossis ua mob rau tantalum.
