Niobium Powder
Kufotokozera
Kutentha kwa chipinda, niobium imakhala yokhazikika mumlengalenga, ndipo imakhala yopanda okosijeni kwathunthu ikakhala yofiyira yotentha mu oxygen. Pa kutentha kwambiri, imatha kuphatikizidwa mwachindunji ndi sulfure, nayitrogeni ndi kaboni kuti apange aloyi ndi titaniyamu, zirconium, hafnium ndi tungsten.Niobium ingagwiritsidwe ntchito ngati chinthu chapamwamba kwambiri. Amagwiritsidwanso ntchito kwambiri mu superalloy, niobium alloy ndi chitsulo. Zimagwiranso ntchito yofunika kwambiri pa chithandizo chamankhwala
