Precious Metal Nb yokhala ndi makina abwino kwambiri

Niobium, yomwe nthawi zambiri imatchedwa Nb, ndi chitsulo chamtengo wapatali chomwe chimagwiritsidwa ntchito kwambiri m'madera osiyanasiyana monga chithandizo chamankhwala, ndege, ndi mafakitale a nyukiliya.Ndipamwamba kwambiri kutentha structural chuma, a m'banja la refractory zitsulo.

Mtundu umodzi wa niobium womwe umagwiritsidwa ntchito kwambiri ndi ufa wa niobium, womwe umapangidwa mwa kuchepetsa niobium oxide mu ng'anjo yotentha kwambiri.Zotsatira zake ndi ufa wabwino, wotuwa-wakuda wokhala ndi chiyero chapamwamba, zomwe zimapangitsa kuti zikhale zoyenera pa ntchito zosiyanasiyana.

Niobium ufa uli ndi zinthu zambiri zothandiza, monga mphamvu zambiri, ductility wabwino, komanso kukana dzimbiri.Nthawi zambiri amagwiritsidwa ntchito popanga zitsulo za ufa, monga kupanga ma superalloys, chifukwa cha malo ake osungunuka komanso amatha kupirira kutentha kwambiri komanso malo ovuta.

M'chipatala, ufa wa niobium umagwiritsidwa ntchito popanga implants zachipatala ndi zipangizo chifukwa cha biocompatibility yake komanso yopanda poizoni.Amagwiritsidwanso ntchito popanga ma scanner a MRI chifukwa cha kuchepa kwa maginito.

M'makampani oyendetsa ndege, ufa wa niobium umagwiritsidwa ntchito popanga zida za injini zotentha kwambiri, monga ma rocket nozzles ndi zishango za kutentha, chifukwa cha mphamvu zake zolemera kwambiri komanso mphamvu zopirira kutentha kwakukulu ndi malo owononga.

M'makampani a nyukiliya, ufa wa niobium umagwiritsidwa ntchito popanga ndodo zamafuta ndi zigawo za riyakitala chifukwa cha mphamvu yake yolimbana ndi kutentha kwakukulu ndi malo owononga.

Ponseponse, ufa wa niobium ndizinthu zosunthika komanso zamtengo wapatali zomwe zimapereka zinthu zapadera ndipo zitha kugwiritsidwa ntchito pazinthu zosiyanasiyana.
