Usetyenziso lweeMveliso zeNiobium
Ukukhuselwa kwe-thermal kunye nezixhobo zesakhiwo kwimizi-mveliso ye-aviation kunye ne-aerospace, iityhubhu ze-elektroniki kunye nezinye izixhobo zombane zokucoca umbane, izinto ezixubileyo ze-superconducting, i-alloys ekwazi ukumelana nobushushu kunye ne-carbides ene-cemented, njl.
Intshayelelo yezinto zeNiobium
Amaphepha ethu e-niobium aqengqeleke ngokubanda kwaye afakwe ivacuum ngamazinga okunciphisa ubunini ukuze kuqinisekiswe isinyithi esifanelekileyo.Iphepha ngalinye lenziwa uhlolo olungqongqo lwemilinganiselo, ukugqitywa komphezulu, kunye nokucaba.
Ishiti leNiobium sesona sinyithi sikhaphukhaphu esirefractory (ubunzima 8.57 g/cc) kwaye inobushushu obuphezulu bokunyibilika (2,468ºC).Le propati ivumela i-alloys yayo ukuba ibonelele ngezisombululo zesakhiwo kumaqondo obushushu aphezulu: ngaphezulu kwe-600ºC kwii-alloys ezisekelwe kwi-nickel kunye nokuphakama njenge-1,300ºC kwi-alloys esekelwe kwi-niobium.
Iphepha leNiobium lineempawu zomzimba kunye neekhemikhali ezifana nezo ze-element tantalum.Ixhathisa i-corrosion njengoko yenza ifilimu ye-dielectric oxide.Isinyithi siqala ukukhupha ioksijini ngokukhawuleza emoyeni kwi-200 ºC.
Ngaphantsi kwe-264ºC, i-niobium ibonisa iimpawu ze-superconducting.Iqhuba ukuxinana okuphezulu kombane okhoyo ngoku ongaxhathisiyo, udala imimandla yamagnetic kunye namandla anika usetyenziso olubalulekileyo olusebenzayo kwimimandla efana noxilongo lwezonyango, uphando lwezixhobo kunye nothutho.
