NIOBIUM - Chinyorwa chekuvandudza chine hukuru hwemangwana
Niobium isimbi yegrey ine chitarisiko chichena chinopenya panzvimbo yakakwenenzverwa. Iyo inoratidzwa nekunyungudika kwakakwira kwe2,477 ° C uye density ye8.58g/cm³. Niobium inogona kuumbwa nyore nyore, kunyangwe pakudziya kwakadzika. Niobium is ductile uye inoitika ne tantalum mune yakasikwa ore. Kunge tantalum, niobium zvakare inoratidzira yakasarudzika makemikari uye oxidation kuramba.

Tsanangudzo:
Chinhu chikuru cheferronobium isimbi yesimbi ye niobium uye iron. Iinewo tsvina yakaita sealuminium, silicon, kabhoni, sarufa, uye phosphorus. Zvinoenderana neiyo niobium yemukati yealloy, yakakamurwa kuita FeNb50, FeNb60 uye FeNb70. Iyo iron alloy inogadzirwa ne niobium-tantalum ore ine tantalum, inonzi niobium-tantalum iron. Ferro-niobium uye niobium-nickel alloys anoshandiswa se niobium additives muvacuum smelting ye iron-based alloys uye nickel-based alloys. Inosungirwa kuva negasi yakaderera uye yakaderera tsvina inokuvadza, yakadai sePb, Sb, Bi, Sn, As, etc. <2 × 10, saka inonzi "VQ" (vacuum quality), yakadai seVQFeNb, VQNiNb, etc.
Application:
Ferroniobium inonyanya kushandiswa kunyungudutsa tembiricha yakakwira (inodzivirira kupisa) alloy, simbi isina tsvina uye yakasimba yakaderera alloy simbi. Niobium inoumba yakagadzikana niobium carbide ine kabhoni musimbi isina tsvina uye simbi inodzivirira kupisa. Inogona kudzivirira kukura kwezviyo pakupisa kwepamusoro, kunatsa chimiro chesimbi, uye kugadzirisa simba, kuoma uye zvinokambaira zvesimbi.
