Cov tsos mob: Sab hauv thiab sab nrauv ntawm cov hlab ntsha qhia cov xim hlau tsis sib xws, tsis muaj oxidation, hydrogenation discoloration, khawb, deformation, burrs, thiab lwm yam.
Cov yam ntxwv: Niobium (Niobium) muaj qhov ntom ntawm 8.57g / cm³, melting point ntawm 2477 degree, thiab kub taw tes ntawm 4744 degree. Nws yog xim nyiaj-grey nrog lub siab ceev thiab qhov ntom ntom.
Niobium yog cov nyiaj-grey, mos thiab ductile tsis tshua muaj siab melting point hlau thiab tam sim no yog cov khoom tseem ceeb tshaj plaws superconducting.
Niobium muaj qhov zoo ntawm qhov kub thiab txias thiab tuaj yeem ua rau txias-siab ua tiav rau hauv daim hlau, rods, xov hlau thiab lwm yam ntaub ntawv. Superconductivity yog qhov zoo tshaj plaws ntawm qhov kub thiab txias, xws li nyob ib ncig ntawm 260 degree , thaum nws tsis kam yog ze rau xoom. Niobium tsis hnov mob nrog huab cua ntawm chav tsev kub thiab tsis oxidize tag nrho thaum liab kub hauv oxygen. Niobium muaj zog ntawm qhov kub thiab txias thiab tseem muaj zog txaus, plasticity thiab thermal conductivity saum 1000 degree. Niobium tuaj yeem raug tshuaj lom neeg ncaj qha nrog sulfur, nitrogen thiab carbon ntawm qhov kub thiab txias. Niobium tsis hnov mob nrog inorganic acids lossis hauv paus, thiab yog insoluble hauv aqua regia, tab sis soluble hauv hydrofluoric acid.
Siv: Petrochemical kev lag luam tshav kub exchanger raj, pas ntsuas kub tiv thaiv tubing, corrosion-resistant high-temperature kev lag luam, aerospace cav, riam phom propulsion, foob pob ua ntxaij cuaj luaj kua ob lub cav, nuclear reactors, submersibles, roj turbines, tsheb cav, diesel xyaw, high- kub furnaces nrog cua sov daim kab xev, high-temperature pwm, high-temperature fixtures, thiab high-temperature crucible ntawm kev tsim khoom.
