Usetyenziso lweeMveliso zeNiobium
Ukukhuselwa kwe-Thermal kunye nezakhiwo kwimizi-mveliso ye-aviation kunye ne-aerospace, iityhubhu ze-elektroniki kunye nezinye izixhobo zombane zokucoca umbane, izinto ze-superconducting, i-alloys ekwazi ukumelana nobushushu kunye ne-cemented carbides, 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 aphezulu 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 nemikhosi evelisa usetyenziso olubalulekileyo olusebenzayo kwimimandla efana noxilongo lwezonyango, uphando lwezixhobo kunye nothutho.
