Niobium yog siv rau hauv cov hlau tsis muaj hlau. Nws txhim kho lub zog ntawm cov alloys, tshwj xeeb tshaj yog nyob rau hauv qis kub. Alloys uas muaj niobium yog siv nyob rau hauv dav hlau cav thiab foob pob ua ntxaij, kab teeb thiab girders rau lub tsev thiab roj rigs, thiab roj thiab roj pipelines. Cov khoom no kuj muaj cov khoom siv superconducting.
Nyobium feem ntau pom nyob qhov twg?
Cov khoom muaj nyob hauv niobite (los yog columbite), niobite-tantalite, parochlore, thiab euxenite. Loj deposits ntawm niobium tau pom muaj txuam nrog carbonatite (carbon-silicate pob zeb), raws li ib tug constituent ntawm parochlore. Ntau cov ore reserves muaj nyob rau hauv Canada, Brazil, Nigeria, Zaire, thiab nyob rau hauv Russia
Niobium siv rau hauv Nigeria yog dab tsi?
Cov nyiaj tso nyiaj loj ntawm Niobium ore tau paub tias tshwm sim hauv Nasarawa, Gombe, Plateau thiab Kogi Xeev nrog rau Tsoom Fwv Teb Chaws Peev. … Niobium yog siv nyob rau hauv arc-welding rods rau stabilized qib ntawm stainless hlau. Nws kuj tseem siv rau hauv cov tshuab cua txias siab heev.
Vim li cas niobium hu ua Niobe?
Niobium yog lub npe rau Greek vajtswv poj niam lub kua muag, Niobe, uas yog tus ntxhais ntawm huab tais Tantalus, raws li Royal Society of Chemistry, vim lub ntsiab zoo sib xws rau tantalum (npe rau huab tais).
Puas niobium siv hauv foob pob hluav taws?
Kev siv Niobium
Raws li C-103 alloy, nws tau siv siv rau lub foob pob hluav taws thiab lub qhov tso pa tawm rau dav hlau cav thiab foob pob hluav taws vim nws lub zog siab thiab oxidation tsis kam ntawm qhov hnyav. Tsis ntev los no, nws tau txais kev pom zoo hauv nws daim ntawv ntshiab rau cov khoom siv semiconductor thiab cov khoom tiv thaiv corrosion.
