nadiifinta sare ee niobium mashiinada qaybo superconducting niobium

Sharaxaad Gaaban:

Maaddooyinka niobium ee kor u kaca ayaa leh codsiyo kala duwan, oo ay ku jiraan magnets-conducting, dardar-geliyaha walxaha iyo mashiinnada MRI.Awoodeeda in ay ku qabato koronto heerkul hooseeya oo leh iska caabin eber ah ayaa ka dhigaysa mid ku habboon codsiyadan.

Waa maxay noocyada kala duwan ee niobium?

Niobium waxay inta badan u jirtaa laba qaab oo isotope deggan: niobium-93 iyo niobium-95.isotopes-yadani waxay ku leeyihiin nukleiyadooda tirooyin kala duwan oo neutrons ah, laakiin dhamaantood waxay muujiyaan sifooyin kiimikaad oo isku mid ah.Marka la eego qaab-dhismeedkeeda crystal, niobium waxay u jiri kartaa qaabab kala duwan, oo ay ku jiraan wejiyada alfa iyo beta, taas oo ku xidhan heerkulka iyo xaaladaha cadaadiska.

Marka lagu daro qaabka asaasiga ah, niobium waxaa laga helaa xeryahooda iyo alaabo kala duwan.Tusaale ahaan, niobium-tin (Nb3Sn) iyo niobium-titanium (Nb-Ti) ayaa caadi ahaan loo isticmaalaa si loo soo saaro silig heer sare ah oo loogu talagalay codsiyada sida mashiinnada MRI iyo dardar-geliyayaasha walxaha.Alloys-yadani waxay muujinayaan sifooyinka sare ee heerkulka hooseeya, iyaga oo ka dhigaya kuwo qiimo leh oo ku yaala goobta sare ee dabeecadda.

Intaa waxaa dheer, niobium waxaa lagu dahaadhi karaa biraha kale si kor loogu qaado hantideeda codsiyada gaarka ah.Tusaale ahaan, niobium waxaa lagu dari karaa zirconium, tantalum ama walxo kale si ay u sameeyaan alloys leh xoog la wanaajiyey, iska caabin daxalka ama sifooyinka sare.

Guud ahaan, noocyada kala duwan ee niobium waxaa ka mid ah qaabkeeda aasaasiga ah, isotopes, qaab dhismeedka crystal, iyo alloys iyo xeryahooda kala duwan, mid kasta oo leh sifooyin gaar ah iyo codsiyo.

Sidee loo soo saaraa niobium?

Niobium waxa lagu helaa habka loo yaqaan habka pyrochlore Brazil.Habka soo saaristu waxa ay ku lug leedahay dhawr marxaladood:

1. Macdanta: Talaabada koowaad waxa ay ku jirtaa in la soo saaro macdano ay ku jiraan niobium, kuwaas oo inta badan lala xidhiidhiyo macdanta kale sida tantalum, tin iyo titanium.Brazil iyo Canada ayaa ah kuwa ugu badan ee soo saara macdanta niobium.

2. Ka faa'iidaysiga macdanta: Macdanta la qoday waxa lagu farsameeyaa si loo ururiyo macdanta niobium.Tani waxay caadi ahaan ku lug leedahay burburin, shiidid iyo farsamooyin kala duwan oo kala duwan si loo kala saaro macdanta niobium ku jirta qaybaha kale ee macdanta.

3. Sifaynta: Macdanta niobium ee la ururiyey waxa ay martaa habab sifeyn dheeraad ah si meesha looga saaro wasakhda oo ay u soo saarto niobium-saar nadiif ah.Tani waxay ku lug yeelan kartaa habaynta kiimikaad, dheecaan ka saarista iyo soo saarista dareeraha si loo helo xeryahooda niobium oo la safeeyey.

4. Dhimista: Xarunta niobium ee la safeeyey ayaa markaa lagu dhimaa niobium bir ah iyada oo loo marayo hannaan heerkul sare ah, badanaa iyada oo la adeegsanayo farsamooyinka sida habka dhimista aluminiumka.Tani waxay keenaysaa soo saarista birta niobium ee qaabka budada ah.

5. Isku-dubarid: Budada niobium ayaa markaa la isugu geeyaa qaab adag iyada oo loo marayo hababka sida biraha budada ah, foornada ama farsamooyinka kale ee samaynta si loo soo saaro niobium ingots, go'yaal ama qaabab kale oo la doonayo.

Guud ahaan, wax-soo-saarka niobium waxay ku lug leedahay tillaabooyin taxane ah oo lagu soo saarayo, lagu sifaynayo laguna farsameeyo macdanta niobium ka kooban si loo helo biraha niobium-ka saafiga ah ee sarreeya si loogu isticmaalo codsiyada warshadaha kala duwan.
