    Kugwiritsa ntchito

    1. Ndalama: Pandalama, golidi ndi siliva ndi ultrafine niobium nanopowder nthawi zina amagwiritsidwa ntchito limodzi ngati chitsulo chamtengo wapatali mu ndalamazo.

    2. Super alloys: gawo lalikulu la niobium ku mawonekedwe achitsulo oyera kapena mawonekedwe a niobium apamwamba kwambiri ndi niobium iron-nickel alloy, omwe amagwiritsidwa ntchito popanga nickel, chromium ndi iron-base super alloys world. Ma alloys awa angagwiritsidwe ntchito mu injini za jet, injini za turbine zamagesi, zida za rocket, ma turbocharger ndi kutentha kwa zida zoyaka;

    3. Chitsulo Kugwiritsa Ntchito: muzinthu zosiyanasiyana zazing'ono zachitsulo muzitsulo, zinyalala za niobium ndizothandiza kwambiri zopangira ma micro-alloying, udindo wa niobium ndi waukulu kwambiri moti maatomu achitsulo ali olemera mu atomu ya niobium, tikhoza kukwaniritsa ntchito zopititsa patsogolo Zolinga zachitsulo. Kwenikweni Zitsulo anawonjezera 0.001% -0.1% niobium, ndi zokwanira kusintha makina katundu zitsulo;
