Ukuhlanzeka okuphezulu kwe-Ferro Niobium esitokweni
I-Niobium - okubonakalayo kokusungulwa okunamandla amakhulu wesikhathi esizayo
I-Niobium iyinsimbi empunga ekhanyayo enokubukeka okumhlophe okukhazimulayo ezindaweni ezibunjiwe. Ibonakala iphuzu eliphakeme elincibilikayo le-2,477 ° C kanye nobude be-8.58g / cm³. I-niobium ingakhiwa kalula, ngisho nasemazingeni okushisa aphansi. I-niobium i-anclile futhi yenzeka nge-tantalum nge-ore yemvelo. NjengoTantalum, uNiobium ubuye anikeze ukumelana okuvelele kwamakhemikhali kanye noxidation.

Ukufanisa:
Ingxenye eyinhloko ye-FerronioBium yi-aroy yensimbi ye-niobium nensimbi. Futhi iqukethe ukungcola okufana ne-aluminium, i-silicon, ikhabhoni, isibabule, ne-phosphorus. Ngokusho kokuqukethwe kwe-niobium ye-alloy, ihlukaniswe nge-FENB50, FENB60 ne-FENB70. I-iron alloy ekhiqizwe nge-niobium-tantalum ore iqukethe i-tantalum, ebizwa nge-niobium-tantalum iron. I-Ferro-niobium ne-niobium-nickel alloys isetshenziswa njengezengezo ze-niobium ekunciphiseni i-vacuum kwama-alloys asuselwa kwi-iron kanye nama-alloys asuselwa ku-nickel. Kuyadingeka ukuthi kube nokuqukethwe okuphansi kwegesi nokungcola okuphansi okune-PB, njenge-PB, SB, BI, SNI, ngakho-ke ibizwa nge- "vq" (ikhwalithi ye-VQNINB), njenge-VQEnB, VQNINB, njll.
Isicelo:
I-Ferronioobium isetshenziselwa ikakhulukazi ukubhema izinga lokushisa eliphakeme (ukumelana nokushisa) i-alloy, insimbi engagqwali kanye namandla aphezulu wensimbi ephansi. I-Niobium yenza amafomu e-carbiium carbiium ezinzile ngekhabhoni ngensimbi engenasici kanye nensimbi yokuvimbela ukushisa. Kungavimbela ukukhula okusanhlamvu ekushiseni okuphezulu, Hlaziya ukwakheka kwensimbi, futhi uthuthukise amandla, ubulukhuni kanye nezindawo zokushaywa kwensimbi
