Kuyera Kwambiri Ferro Niobium Kulipo

NIOBIUM - Zinthu zopangira zatsopano zomwe zili ndi kuthekera kwakukulu kwamtsogolo

Niobium ndi chitsulo chopepuka cha imvi chokhala ndi mawonekedwe oyera owala pamwamba pa zinthu zopukutidwa. Chimadziwika ndi kutentha kwambiri kwa 2,477°C komanso kuchuluka kwa 8.58g/cm³. Niobium imatha kupangidwa mosavuta, ngakhale kutentha kutakhala kochepa. Niobium ndi yofewa ndipo imapezeka ndi tantalum mu miyala yachilengedwe. Monga tantalum, niobium imakhalanso ndi kukana kwapadera kwa mankhwala ndi okosijeni.

Kufotokozera：

Gawo lalikulu la ferroniobium ndi aloyi yachitsulo ya niobium ndi chitsulo. Ilinso ndi zinthu zosafunika monga aluminiyamu, silicon, carbon, sulfure, ndi phosphorous. Malinga ndi kuchuluka kwa niobium mu aloyi, imagawidwa mu FeNb50, FeNb60 ndi FeNb70. Aloyi yachitsulo yopangidwa ndi niobium-tantalum ore ili ndi tantalum, yotchedwa niobium-tantalum iron. Ferro-niobium ndi niobium-nickel alloys zimagwiritsidwa ntchito ngati zowonjezera za niobium pakusungunula vacuum alloys zopangidwa ndi chitsulo ndi nickel alloys. Imafunika kukhala ndi mpweya wochepa komanso zinthu zosafunika kwenikweni, monga Pb, Sb, Bi, Sn, As, etc. <2×10, kotero imatchedwa "VQ" (ubwino wa vacuum), monga VQFeNb, VQNiNb, etc.

Kugwiritsa ntchito：

Ferroniobium imagwiritsidwa ntchito makamaka posungunula aloyi yotentha kwambiri (yosatentha), chitsulo chosapanga dzimbiri komanso chitsulo chopanda mphamvu kwambiri. Niobium imapanga niobium carbide yokhazikika yokhala ndi kaboni mu chitsulo chosapanga dzimbiri komanso chitsulo chopanda kutentha. Imatha kuletsa kukula kwa tirigu pa kutentha kwakukulu, kukonza kapangidwe ka chitsulo, ndikuwonjezera mphamvu, kulimba ndi mphamvu zoyenda zachitsulo.
