Chiyero chachikulu cha Ferro Niobium m'matumba
Niobium - chinthu chazakudya zomwe zingatheke mtsogolo
Niobium ndi chitsulo chopepuka cha imvi chokhala ndi mawonekedwe oyera oyera pamanja. Amadziwika ndi malo okwanira 2,477 ° C ndi kachulukidwe wa 8.58g / cm³. Niobium ikhoza kupangidwa mosavuta, ngakhale kutentha kochepa. Niobium ndi duckile ndipo imachitika ndi tantalum mu ore. Monga Tantlum, Niobium ilinso ndi kukana kwa mankhwala ndi oxidation.

Kaonekeswe:
Gawo lalikulu la Ferroniobium ndi chitsulo cha niobium ndi chitsulo. Mulinso zodetsa monga aluminiyamu, silicon, kaboni, sulufule, ndi phosphorous. Malinga ndi Niobium zomwe zili mu AloY, zimagawidwa ku Fenb50, Fenb60 ndi Fenb70. Aloya wachitsulo chopangidwa ndi Niobium-tantalum Ore ali ndi Tantalum, yemwe amatchedwa Niobium-Timel Iron. Ferro-Niobium ndi Niobium-Nickel-Nickel-Nickel-Niobiums amagwiritsidwa ntchito ngati Niobium Zowonjezera Pa vacuum wosungunuka wa zisudzo ndi ma aldoys okhazikika. Akufunika kukhala ndi zokhumudwitsa zamagesi komanso zosafunikira zovulaza, monga pb, sb, sn, etc. vqnunb, vqninb, etc.
Karata yanchito:
Ferroniobium imagwiritsidwa ntchito makamaka yopukutira kutentha kwambiri (yotentha yotentha) iloy, chitsulo chosapanga dzimbiri komanso nyonga yayikulu kwambiri. Niobium amakongoletsa ndodo yokhazikika niobium carbide ndi kaboni mu chitsulo chosapanga dzimbiri komanso chitsulo chotenthetsera. Zimatha kuletsa kukula kwa tirigu pamtunda wambiri, kukonza kapangidwe kake, ndikusintha mphamvu, kulimba ndi kupindika katundu wa chitsulo
