xoogga xajinta sare 99.95% siligga Niobium
Siliga Niobium waa badeecad niobium saafi ah oo nadiif ah oo leh 99.95% nadiif ah, oo badanaa loo yaqaan silig niobium. Walxaha ceeriin ee lagu sameeyo siligga niobium waa niobium nadiif ah oo sarreeya, kaas oo laga sameeyo walxo niobium ah oo loo maro hababka wax-soo-saarka caagga ah. Balaastigiisa wanaagsan ee heerkulka qolka awgeed, niobium waxa ay mari kartaa habaynta qallafsanaanta sida rogid, sawirid, leexin, iyo foorarid iyada oo aan kuleyl lahayn.

1. Soo saarista alaabta ceeriin
(Niobium inta badan waxaa laga soo saaraa macdanta pyrochlore)
2. Sifaynta
(Niobium-ka la soo saaray ayaa markaa la sifeeyaa si looga saaro wasakhda oo loo abuuro bir niobium nadiif ah oo sarreeya)
3. Dhalinta iyo tuurista
(Niobium-ka la safeeyey waa la dhalaaley waxaana lagu tuuraa jeexjeexyada ama qaabab kale oo ku habboon habayn dheeraad ah)
4. sawir silig
(Ingots niobium ayaa markaa lagu farsameeyaa iyada oo loo marayo sawirro taxane ah oo silig ah ayaa dhinta si loo yareeyo dhexroorka birta loona abuuro dhumucda siliga la rabo)
5. Annealing
(Siliga niobium ayaa markaa la tirtiraa si loo yareeyo walbahaarka oo loo hagaajiyo ductility iyo shaqeyn)
6. Daaweynta dusha sare
(nadiifinta, dahaarka, ama habab kale si kor loogu qaado hantideeda ama looga ilaaliyo daxalka)
7. Xakamaynta tayada
- Magnets-conducting-ka sare: Siliga Niobium waxa loo isticmaalaa in lagu soo saaro magnets awood sare leh oo loogu talagalay codsiyada sida mishiinnada magnetic resonance imaging (MRI), dardar-geliyayaasha walxaha, iyo tareenada maglev (magnetic levitation).
- Aerospace: Silig Niobium waxaa loo isticmaalaa warshadaha hawada hawada codsiyada sida matoorada diyaaradaha, marawaxadaha gaaska, iyo gantaalada kicinta nidaamka sababtoo ah ay awood heerkulka sare iyo caabbinta daxalka.
- Aaladaha caafimaadka: Sida ay ula jaanqaadi karaan noolaha iyo iska caabbinta daxalka ee jidhka bini'aadamka awgeed, siligga niobium waxaa loo isticmaalaa aaladaha caafimaadka sida qalab-sameeyayaasha, defibrillators la rakibo iyo qalabyada kale ee caafimaadka.
- Habka soo saarista isku dhafan: Habka soo saarista iyo sifaynta niobium waa mid adag oo u baahan qalab iyo khibrad gaar ah. Tani waxay kordhin doontaa kharashyada wax soo saarka waxayna saameynaysaa qiimaha suuqa ee niobium. Codsiyada xirfadlayaasha ah: Niobium waxaa lagu qiimeeyaa sifooyinkeeda gaarka ah, sida superconductivity, caabbinta daxalka, iyo xoogga heerkulka sare. Guryahani waxay ka dhigaan wax caan ah oo loogu talagalay codsiyada gaarka ah ee warshadaha sida hawada, caafimaadka iyo elektiroonigga, taas oo kor u qaadi karta qiimaheeda.
Niobium waa bir jilicsan oo jilicsan. Adaggeedu waxa uu la mid yahay titanium saafi ah waxana uu leeyahay adayg aad u hooseeya marka loo eego biro kale oo badan. Jilicsanaantan iyo ductility ayaa ka dhigaysa niobium si fudud in loo habeeyo, taasoo u oggolaanaysa in loo sameeyo qaabab iyo qaabab kala duwan oo ku habboon codsiyada kala duwan.
Niobium waxaa loo isticmaalaa wax soo saarka birta sababtoo ah waxay kordhisaa xoogga, adkaanta iyo qaabaynta birta. Marka lagu daro birta xaddi yar, niobium waxay samaysaa carbide oo sifaysa qaab dhismeedka hadhuudhka birta oo joojiya korriinka hadhuudhka marka birta ay qaboojiso. Wax ka beddelkaani wuxuu wanaajin karaa sifooyinka farsamada sida xoogga kordhay, adkaanta, iyo caabbinta xirashada iyo daalka. Intaa waxaa dheer, niobium waxay hagaajin kartaa alxanka iyo guryaha kuleylku saameeyay ee birta, taas oo ka dhigaysa walxo qiimo leh oo ku jira codsiyada birta ee kala duwan, oo ay ku jiraan qaybaha baabuurta, tuubooyinka, qalabka dhismaha, iyo birta hoose ee xoogga badan (HSLA). .
