Kev piav qhia txog khoom
Niobium ntawv ci yog siv rau hauv: kev lag luam superconducting, kub resistant, corrosion resistant kev lag luam, aerospace, tshuaj thiab tshuaj lom neeg kev lag luam, siv rau hauv kev tsim cov tib neeg implants, thiab lwm yam.
Niobium yog ib hom hlau grey ci ntsa iab uas yog paramagnetic thiab koom nrog pawg 5 ntawm lub rooj periodic. Cov hlau niobium uas muaj purity siab yog ductile ntau dua, tab sis nws tawv thaum muaj cov impurity ntau ntxiv.
*Niobium ruaj khov hauv huab cua ntawm chav tsev kub, thiab tsis oxidized tag thaum nws kub liab hauv oxygen. Nws ncaj qha sib xyaw nrog sulfur, nitrogen thiab carbon ntawm qhov kub siab, thiab tuaj yeem tsim cov alloys nrog titanium, zirconium, hafnium thiab tungsten. Nws tsis cuam tshuam nrog inorganic acids lossis bases, thiab nws tsis yaj hauv aqua regia, tab sis nws yaj hauv hydrofluoric acid. Cov xeev oxidation ntawm niobium yog -1, +2, +3, +4 thiab +5, uas +5 yog cov tshuaj ruaj khov tshaj plaws.
