Isiqondiso sokuthuthukiswa kwemakethe ye-tantalum ne-niobium

Yiziphi izinhlobo ze-ore ze-tantalum-niobium deposits?

Izidiphozi ze-Tantalum-niobium zingahlukaniswa zibe yizigaba ezinhlanu ngokuya ngohlobo lwazo: amadiphozithi we-magmatic, ama-Weijing, Amadepositi e-hydrothermal akha umhwamuko, oxhumana namadiphozithi okuzimela kanye nama-exogenous. Amaminerali e-tantalum ne-niobium anenani lezimboni ikakhulukazi afaka i-tantalite, i-niobium iron ore, i-chlore ephuzi, i-yttrium niobium ore ensundu, i-ore emnyama engavamile, i-titanium niobium calcium cerium ore, itshe le-tantalum lime lime, i-uranium tantalum niobium ore, itshe elihle, itshe lesisombululo elula, Njll. Usayizi wamadiphozithi e-tantalum-niobium akhiwe ngamadwala athwala izinhlobo ezahlukahlukene enezinhlobo zediphozi ayahluka kakhulu.

I-Tantalum (Ta) ne-niobium (Nb) yizinsimbi ezingandile ezinendawo yokuncibilika ephezulu (tantalum 2996 ℃, i-niobium 2468 ℃) nendawo yokubilisa ephezulu (tantalum 5427 ℃, niobium 5127 ℃). Ubuningi be-tantalum ngu-16.65 g / cm³; Ubuningi be-niobium ngu-8.57 g / cm³. Ukubukeka kufana nensimbi, ukhanya okumhlophe okumpunga, impuphu impunga emnyama, ene-sction, ukumelana nokugqwala, i-superconductivity, ukuqhutshwa kwe-unipolar namandla aphezulu ekushiseni okuphezulu.

Ukusika nokusetshenziswa kwe-Tantalum Plate, i-Tantalum Foil ne-Tantalum Machining Parts

Indawo yokuncibilika ye-tantalum ingu-2980 ℃, okungowesibili kuphela ku-tungsten (3380 ℃) ezinsimbi ezivamile ezikhungathekile, futhi ubuningi ngu-16.67 g / cm3. Esimweni esine-annealed, i-tantalum inepulasitiki enhle futhi izinzile kakhulu emazingeni okushisa aphezulu, yamunca futhi agcine amagesi. I-Tantalum imelana ne-asidi futhi iyinto eyi-biocompatible. I-Tantalum isetshenziswa kabanzi ezimbonini ze-elekthronikhi, zamakhemikhali, ezokwelapha nezinye izimboni. Ngasikhathi sinye, i-tantalum nayo iyinto ebalulekile yokukhiqiza i-carbide esemementedi.
