Koj paub dab tsi txog niobium? Yog tias koj zoo li cov neeg feem coob, cov lus teb tsis ntau. Tiam sis, paub qhov no: niobium siv rau txhua yam, los ntawm cov hniav nyiaj hniav kub hypoallergenic mus rau cov hlau nplaum superconducting. Koj yuav txawm pom niobium hauv qee lub cav dav hlau.
Niobium Character
Niobium yog ci ntsa iab, cov hlau dawb uas yuav tig ntxoov ntxoo ntawm xiav, ntsuab los yog daj thaum raug rau huab cua. Nrog rau lub atomic xov tooj ntawm 41 thiab lub cim Nb, niobium muaj ib tug atomic nyhav ntawm 92.906 thiab ib tug ceev ntawm 8.57 grams ib cubic centimeter. Nyob rau hauv chav tsev kub nws yog khov. Niobium lub melting point yog 4,491 degrees Fahrenheit thiab nws kub taw tes yog 8,571 degrees F.
Niobium Keeb Kwm
Niobium siv los hu ua columbium nyob rau hauv lub U.S.. rau qee qhov 100 Xyoos, whereas nws yog niobium hauv Tebchaws Europe. Nws muaj keeb kwm nyuaj, tab sis txaus nws los hais tias niobium tau zoo nkauj npaum li cas 'xam tawm' nyob rau hauv nruab nrab xyoo 1800. Ib puag ncig 1950, International Union of Pure and Applied Chemistry officially saws niobium raws li lub npe ntawm lub ntsiab lus, hauv kev txiav txim siab rau kev siv European. Uas tau hais tias, tej zaum koj tseem yuav pom qee tus uas xa mus rau nws li columbium!
Qhov twg Niobium Pom thiab Siv
Hauv xwm, niobium is almost always found with tantalum. Today it’s found and mined in Brazil and Canada, with enough to last for probably the next five centuries according to experts.
Where is niobium most utilized? That would be in the steel industry. It’s used to create high-strength, low-alloy steels. Niobium is used to increase toughness as well as corrosion resistance.
Thaum kawg, niobium is known as one of the five refractory metals, all of which have very high resistance to heat and wear.
Need niobium? You’re in luck– Eagle Alloys, an industrial metal supplier, has it for sale in a variety of forms. You can also call Eagle Alloys at 800-237-9012 for more information about niobium.
