mkulu wamakokedwe mphamvu 99.95% Niobium waya
Waya wa Niobium ndi chinthu choyera kwambiri cha niobium chokhala ndi chiyero cha 99.95%, chomwe chimatchedwa waya wa niobium. Zopangira zopangira waya wa niobium ndi niobium yoyera kwambiri, yomwe imapangidwa kukhala filamentous niobium zakuthupi kudzera mu njira zopangira pulasitiki. Chifukwa cha pulasitiki yake yabwino kutentha kutentha, niobium imatha kusinthika monga kugudubuza, kujambula, kupindika, ndi kupindika popanda kutentha.

1. Zopangira zopangira
(Niobium nthawi zambiri imachokera ku mineral pyrochlore)
2. Kuyenga
(Niobium yochotsedwayo imayeretsedwa kuti ichotse zonyansa ndikupanga chitsulo cha niobium choyera kwambiri)
3. Kusungunula ndi kuponya
(Niobium yoyengedwa imasungunuka ndikuponyedwa mu ingots kapena mitundu ina yoyenera kukonzedwanso)
4.Kujambula kwawaya
(Ma niobium ingots amasinthidwa kudzera muzojambula zingapo zamawaya kuti achepetse kukula kwachitsulo ndikupanga makulidwe a waya omwe mukufuna)
5. Kudziletsa
(Waya wa niobium ndiye amalumikizidwa kuti athetse kupsinjika kulikonse ndikuwongolera kukhazikika kwake komanso kugwira ntchito)
6. Chithandizo chapamwamba
(kuyeretsa, kupaka, kapena njira zina zowonjezera katundu wake kapena kuziteteza ku dzimbiri)
7. Kuwongolera khalidwe
- Maginito a Superconducting: Waya wa Niobium umagwiritsidwa ntchito kupanga maginito opangira maginito ogwiritsira ntchito monga makina a magnetic resonance imaging (MRI), particle accelerators, ndi maglev (magnetic levitation) masitima apamtunda.
- Azamlengalenga: Waya wa Niobium umagwiritsidwa ntchito m'makampani opanga ndege ngati injini zandege, makina opangira gasi, ndi makina oyendetsa ma rocket chifukwa champhamvu yake yotentha komanso kukana dzimbiri.
- Zipangizo zamankhwala: Chifukwa cha biocompatibility ndi kukana dzimbiri m'thupi la munthu, waya wa niobium amagwiritsidwa ntchito pazida zamankhwala monga ma pacemaker, implantable defibrillators ndi implants zina zamankhwala.
- Njira yovuta yochotsera niobium: Kuchotsa ndi kuyenga kwa niobium ndizovuta ndipo kumafuna zida zapadera komanso ukadaulo. Izi zidzawonjezera ndalama zopangira ndipo zidzakhudza mtengo wa msika wa niobium.Mapulogalamu aukadaulo: Niobium imayamikiridwa chifukwa cha zinthu zake zapadera, monga superconductivity, kukana kwa dzimbiri, komanso mphamvu yotentha kwambiri. Zinthuzi zimapangitsa kuti zikhale zodziwika bwino pamafakitale monga zakuthambo, zamankhwala ndi zamagetsi, zomwe zimatha kukweza mtengo wake.
Niobium ndi chitsulo chofewa komanso ductile. Kulimba kwake ndi kofanana ndi titaniyamu yoyera ndipo imakhala yolimba pang'ono poyerekeza ndi zitsulo zina zambiri. Kufewa ndi kukhazikika kumeneku kumapangitsa niobium kukhala yosavuta kuyipanga, kulola kuti ipangidwe m'mapangidwe osiyanasiyana kuti igwirizane ndi ntchito zosiyanasiyana.
Niobium imagwiritsidwa ntchito popanga zitsulo chifukwa imawonjezera mphamvu, kulimba komanso mawonekedwe achitsulo. Akawonjezeredwa kuchitsulo pang'ono, niobium imapanga ma carbides omwe amayenga kapangidwe kake kachitsulo ndikuletsa kukula kwa njere pamene chitsulo chikuzizira. Kusintha kumeneku kumatha kukonza zinthu zamakina monga kuchuluka kwa mphamvu, kuuma, komanso kukana kuvala ndi kutopa. Komanso, niobium akhoza kusintha weldability ndi kutentha anakhudzidwa zone katundu wa zitsulo, kupanga kukhala chinthu chofunika alloying zinthu zosiyanasiyana ntchito zitsulo, kuphatikizapo zigawo magalimoto, mapaipi, zomangamanga, ndi mkulu-mphamvu otsika aloyi (HSLA) zitsulo. .
