Znanstvenici u Kini otkrili su dosad nevi\u0111enu vrstu rude koja sadr\u017ei element rijetke zemlje koji je tra\u017een zbog svojih supravodljivih svojstava. Ruda, nazvana niobobaotit, napravljena je od niobija, barija, titana, \u017eeljeza i klorida, izvijestio je South China Morning Post. Niobij je taj koji izaziva uzbu\u0111enje: ovaj svijetlosivi metal trenutno se uglavnom koristi u proizvodnji \u010delika, koji oja\u010dava bez dodavanja zna\u010dajne te\u017eine. Niobij se tako\u0111er koristi u izradi drugih legura (materijala izra\u0111enih od mje\u0161avina metala) i mo\u017ee se na\u0107i u akceleratorima \u010destica i drugoj naprednoj znanstvenoj opremi jer je supravodi\u010d na niskim temperaturama, prema Kraljevskom kemijskom dru\u0161tvu.<\/p>\n\n\n\n

Le\u017ei\u0161te je prona\u0111eno u nalazi\u0161tu rude Bayan Obo u gradu Baotou u Unutra\u0161njoj Mongoliji 3. listopada. Sme\u0111e-crna ruda je 17. nova vrsta prona\u0111ena u le\u017ei\u0161tu i jedan od 150 novih minerala prona\u0111enih u regiji, prema Kineska nacionalna nuklearna korporacija (CNNC).<\/p>\n\n\n\n

\u010cemu zapravo slu\u017ei<\/strong><\/p>\n\n\n\n

Ovo otkri\u0107e bi moglo biti velika dobit za Kinu, koja trenutno uvozi 95% svog niobija.<\/p>\n\n\n\n

“Ovisno o koli\u010dini i kvaliteti ovog niobija, mogao bi Kinu u\u010diniti samodostatnom”, rekao je za novine Antonio H. Castro Neto, profesor elektrotehnike i ra\u010dunalnog in\u017eenjerstva na Nacionalnom sveu\u010dili\u0161tu u Singapuru (NUS). Brazil je najve\u0107i svjetski dobavlja\u010d metala rijetke zemlje, a Kanada je daleko druga. Prema Geolo\u0161kom institutu SAD-a, u ju\u017enoj Nebraski u tijeku je projekt otvaranja rudnika i pogona za preradu niobija. Elk Creek Critical Minerals Project bio bi jedini rudnik niobija u SAD-u.<\/p>\n\n\n\n

Metal bi tako\u0111er mogao biti u ve\u0107oj potra\u017enji u budu\u0107nosti, budu\u0107i da istra\u017eiva\u010di rade na razvoju niobij-litijskih i niobij-grafenskih baterija. Prema S&P Globalu, ove baterije mogu smanjiti rizik od po\u017eara ako se koriste zajedno s litijem. Niobij-litijeve baterije tako\u0111er se pune br\u017ee i mogu se puniti \u010de\u0161\u0107e od tradicionalnih litijevih baterija. U svibnju su istra\u017eiva\u010di u Centru za napredne 2D materijale (CA2DM) na NUS-u, koji razvija niobij-grafenske baterije, rekli da bi baterije mogle trajati oko 30 godina – 10 puta dulje od litij-ionskih baterija – i da se mogu potpuno napuniti u manje od 10 minuta.<\/p>\n\n\n\n
