Tantalum muaj ib lub siab melting ntsiab lus ntawm tag nrho cov hais rau ntiaj teb. Nws melting taw tes sits ntawm kwv yees li 5,462 degrees Fahrenheit, Uas txo nws hwj nws qab xwb tungsten thiab rhenium kom deb li deb melting ntsiab lus yog txhawj xeeb. Tsaug nws siab melting taw tes, Nws yog feem ntau siv nyob rau hauv txhua yam los ntawm capacitors thiab nqus furnaces nuclear reactors thiab qhov chaw siv los ua aircrafts. Muaj ntau lwm yam tseeb txog tantalum, ib yam nkaus thiab. Saib ob peb leeg hauv qab no.
Tantalum yog xub sab ntau tshaj 200 xyoo dhau los.
Ib Swedish chemist hu ua Anders Gustaf Ekeberg yog tus thawj neeg mus nrhiav tau tantalum. Nws nrhiav tau nws txoj kev rov qab rau hauv 1802. Tiam sis, thaum xub thawj, Nws ntseeg tau tias tantalum yog tib lub caij li niobium. Nws tsis yog mus txog rau thaum 1844 Tias ib german chemist hu ua Heinrich Rose pom tias tantalum thiab niobium tau ua tau ob lub ntsiab sib txawv. Nws tshawb pom tau backed los ntawm kev tshawb fawb ntxiv ua los ntawm Swiss chemist Jean Charles Galissard tsib Marignac ntau tshaj 20 ob peb xyoos tom qab ntawd.
Nws yog lub npe hu ua tom qab ib daim duab Greek mythological daim duab.
Tom qab Rose sab tias tantalum thiab niobium tau ob tug txawv hais, Nws tuaj nrog lub npe tantalum. Nws hu ua lub caij tom qab Tantalus, Uas yog ib daim duab Greek mythological daim duab. Tus tub zeus, Tantalus yog rau txim hauv Greek mythology los yuam sawv ntsug hauv dej li txiv hmab txiv ntoo dangled dua nws lub taub hau cia li tawm hauv nws mus txog.
Nws yuav nrhiav tau nyob rau hauv ib handful ntawm lub teb chaws thoob ntiaj teb.
Tantalum yuav tau founded lawm hauv ib mineral hu ua columbite-tantalite. Qhov mineral no feem ntau pom muaj nyob rau tej qho chaw xws li Australia, Brazil, Canada, Nigeria, Portugal, thiab ntau lwm lub teb chaws. Electrolysis yuav tsum siv los ua kev sib cais ntawm tantalum thiab niobium tom qab nws nyob.
Ib lwm nthuav tshaj plaws txog tantalum yog tias nws yog ductile, Nws txhais tau tias nws yuav tau twv tawm thiab muab rau hauv ib lub hlau zoo heev. Dav dawb hau Alloys, peb kuj tseem muaj peevxwm tantalum bars, daim ntawv, phaj, rhawv, thiab foil. Yog xav paub ntxiv txog kev muab tantalum, hu rau peb ntawm 800-237-9012 Hnub no.
