NIOBIUM - Zopangira zatsopano zomwe zili ndi tsogolo labwino
Niobium ndi chitsulo chotuwa chopepuka komanso choyera chonyezimira pamalo opukutidwa. Amadziwika ndi kusungunuka kwakukulu kwa 2,477 ° C ndi kachulukidwe ka 8.58g/cm³. Niobium imatha kupangidwa mosavuta, ngakhale pa kutentha kochepa. Niobium ndi ductile ndipo imapezeka ndi tantalum mu miyala yachilengedwe. Monga tantalum, niobium imakhalanso ndi mankhwala apadera komanso kukana kwa okosijeni.

Kufotokozera:
Chigawo chachikulu cha ferronobium ndi aloyi yachitsulo ya niobium ndi chitsulo. Mulinso zonyansa monga aluminium, silicon, carbon, sulfure, ndi phosphorous. Malinga ndi niobium zomwe zili mu alloy, zimagawidwa mu FeNb50, FeNb60 ndi FeNb70. Chitsulo chopangidwa ndi niobium-tantalum ore chili ndi tantalum, yotchedwa niobium-tantalum iron. Ferro-niobium ndi niobium-nickel alloys amagwiritsidwa ntchito ngati zowonjezera za niobium posungunula zitsulo zopangidwa ndi chitsulo ndi nickel-based alloys. Zimafunika kukhala ndi mpweya wochepa komanso zowonongeka zowonongeka, monga Pb, Sb, Bi, Sn, As, etc. <2 × 10, choncho amatchedwa "VQ" (vacuum quality), monga VQFeNb, VQNiNb, ndi zina.
Kugwiritsa ntchito:
Ferroniobium imagwiritsidwa ntchito makamaka pakusungunula kutentha kwambiri (kukana kutentha) aloyi, chitsulo chosapanga dzimbiri komanso chitsulo champhamvu chotsika kwambiri. Niobium imapanga niobium carbide yokhazikika yokhala ndi mpweya muzitsulo zosapanga dzimbiri ndi chitsulo chosagwira kutentha. Zingalepheretse kukula kwambewu pa kutentha kwakukulu, kuyeretsa kapangidwe kachitsulo, ndikuwongolera mphamvu, kulimba ndi kukwawa kwachitsulo.
