Masayendisiti ekuEurope anogona kunge akawana nzira yekugadzira magineti emhepo turbines uye mota dzemagetsi pasina kushandisa isingawanzo pasi simbi.
Vatsvakurudzi veBritish neAustria vakawana nzira yekugadzira tetrataenite. Kana maitiro ekugadzira achikwanisika kutengeserana, nyika dzekumadokero dzichaderedza zvakanyanya kuvimba neChina isingawanzo simbi dzepasi.
Tetrataenite ialloy yesimbi uye nickel, ine chaiyo atomu chimiro. Inowanikwa mune iron meteorites uye inotora mamiriyoni emakore kuti iumbe zvakasikwa mumatenga.
Mumakore ekuma1960, masayendisiti akarova iron nickel alloy nemanyutroni kuronga maatomu maererano nechimiro chakati uye chekugadzira tetrataenite, asi tekinoroji iyi haina kukodzera kugadzirwa kwakakura.
Vatsvakurudzi vanobva kuYunivhesiti yeCambridge, Austrian Academy of Sciences uye Montanuniversität muLeoben vakaona kuti kuwedzera phosphorus, chinhu chakajairika, kune imwe yakafanira yesimbi uye nickel, uye kudurura alloy muforoma inogona kubudisa tetrataenite pamwero mukuru. .
Vatsvakurudzi vanotarisira kushanda pamwe chete nevakurumagineti vagadzirikuona kana tetrataenite yakakodzerahigh-performance magineti.
High performance magineti tekinoroji yakakosha yekuvaka zero kabhoni hupfumi, zvikamu zvakakosha zvejenareta uye mota dzemagetsi. Parizvino, zvisingawanzo zvinhu zvepasi zvinofanirwa kuwedzerwa kugadzira magineti epamusoro. Rare earth metals haawanike mugoko repasi, asi kukwenenzvera kwakaoma, kunoda kushandisa simba rakawanda nekukuvadza nharaunda.
Purofesa Greer weDepartment of Materials Science and Metallurgy of Cambridge University, uyo akatungamirira tsvakurudzo yacho, akati: “Kune nzvimbo dzisingawanzoitiki dzevhu mune dzimwe nzvimbo, asi migodhi inoparadza zvikuru: chiverengero chikuru chesimbi chinofanira kucherwa chisati chiduku. zvemasimbi epasi asingawanzo kutorwa kubva mazviri. Pakati pekukanganisa kwezvakatipoteredza uye kuvimba kwakanyanya neChina, zvinokasira kutsvaga zvimwe zvinhu zvisingashandisi simbi dzepasi. "
Parizvino, inopfuura 80% yenyika isingawanzo simbi dzepasi uyemagineti epasi asingawanzoinogadzirwa muChina. Mutungamiri weUnited States, Biden, vakamboratidza rutsigiro rwekuwedzera kuburitswa kwezvinhu zvakakosha, ukuwo EU ichikurudzira kuti nyika dzenhengo dzisiyane macheni adzo uye dzidzivise kuvimba zvakanyanya neChina nemimwe misika imwe chete, kusanganisira isingawanzo simbi dzepasi.
