Txheej txheem cej luam
Niobium (Nb) Cov ntaub ntawv dav dav:
Niobium, lub cim cim: Nh, Atomic Number 41, yog VB pawg hlau. Qhov ceev ntawm 8.57 g / cm ', lub melting point ntawm 2477 ° C thiab boiling point ntawm 4744 ° C.
Niobium yog nyiaj-grey, mos thiab ductile tsawg-melting-point hlau. Tsis hnov mob nrog huab cua ntawm chav tsev kub thiab tsis yog oxidized kiag li thaum liab-kub hauv oxygen.
Niobium tuaj yeem ua ke ncaj qha nrog cov sulfur, nitrogen thiab carbon ntawm qhov kub thiab txias.Does tsis hnov mob nrog inorganic acids los yog hauv paus, thiab tsis poob rau hauv aqua regia,
tab sis yog soluble hauv hydrofluoric acid. Cov ntsiab lus ntawm niobium nyob rau hauv lub crust yog 20ppa,
thiab kev faib cov peev txheej niobium yog qhov tseem ceeb.
Niobium yog dav siv nyob rau hauv steel Superconductor kev faib tawm, aerospace thiab atomic zog vim nws zoo superconductivity, siab melting point.
corrosion kuj thiab hnav tsis kam.
