Ukucoceka okuphezulu kweFerro Niobium kwiStokhwe
I-NIOBIUM -Isixhobo sokwenziwa kwezinto ezintsha ezinokubakho kwixesha elizayo
I-Niobium sisinyithi esikhanyayo esingwevu kunye nenkangeleko emhlophe emenyezelayo kwindawo ekhazimlisiweyo.Ibonakala kwindawo ephezulu yokunyibilika eyi-2,477°C kunye noxinzelelo lwe-8.58g/cm³.I-Niobium inokubunjwa ngokulula, nakwiqondo lokushisa eliphantsi.I-Niobium yi-ductile kwaye yenzeka nge-tantalum kwintsimbi yendalo.Njenge-tantalum, i-niobium ikwabonisa ukuchasana kweekhemikhali kunye ne-oxidation.

Inkcazo:
Icandelo eliphambili le-ferronobium yintsimbi yensimbi ye-niobium kunye nentsimbi.Kwakhona iqulethe ukungcola okufana ne-aluminiyam, i-silicon, i-carbon, isulfure, kunye ne-phosphorus.Ngokomxholo we-niobium we-alloy, ihlulwe ibe yi-FeNb50, i-FeNb60 kunye ne-FeNb70.I-iron alloy eveliswa nge-niobium-tantalum ore iqulethe i-tantalum, ebizwa ngokuba yi-niobium-tantalum iron.I-Ferro-niobium kunye ne-niobium-nickel alloys zisetyenziswa njengezongezo ze-niobium kwi-vacuum smelting ye-iron-based alloys kunye ne-nickel-based alloys.Kudingeka ukuba ube nomxholo wegesi ophantsi kunye nokungcola okuncinci okuyingozi, njengePb, Sb, Bi, Sn, As, njl. <2 × 10, ngoko kuthiwa "VQ" (umgangatho we-vacuum), njengeVQFeNb, VQNiNb, njl.
Isicelo:
I-Ferroniobium isetyenziselwa ukunyibilikisa ubushushu obuphezulu (ubushushu obunganyangekiyo) ingxubevange, intsimbi engatyiwayo kunye namandla aphezulu entsimbi ephantsi.I-Niobium yenza i-niobium carbide ezinzileyo kunye nekhabhoni kwintsimbi engenasici kunye nentsimbi ekwazi ukumelana nobushushu.Inokuthintela ukukhula okuziinkozo kubushushu obuphezulu, icokise ubume bentsimbi, kwaye iphucule amandla, ukuqina kunye neempawu ezirhubuluzayo zentsimbi.
