Chemical Properties ntawmNiobium
Niobium ruaj khov nyob rau hauv huab cua ntawm chav tsev kub thiab tsis oxidize kiag li thaum liab kub hauv oxygen.
Nws ncaj qha ua ke nrog sulfur, nitrogen, thiab carbon ntawm qhov kub thiab txias, thiab tuaj yeem tsim cov alloys nrog titanium, zirconium, hafnium, thiab tungsten.
Nws tsis hnov mob nrog inorganic acids lossis hauv paus, thiab tsis yog nws soluble hauv aqua regia, tab sis yog soluble hauv hydrogen acid.
Niobium hlau yog qhov ruaj khov heev hauv huab cua ntawm chav tsev kub thiab tsis cuam tshuam nrog huab cua.
Txawm hais tias nws muaj qhov siab melting point (2468 degree) nyob rau hauv nws lub xeev elemental, nws qhov ntom yog qis dua lwm cov hlau refractory.
Niobium kuj tseem tiv taus ntau hom kev xeb thiab tuaj yeem tsim cov dielectric oxide txheej.
