Izazinzulu zaseYurophu zisenokuba zifumene indlela yokwenza iimagnethi zeeinjini zomoya kunye neenqwelo zombane ngaphandle kokusebenzisa iintsimbi zomhlaba ezinqabileyo.
Abaphandi baseBrithani nabase-Austrian bafumana indlela yokwenza i-tetrataenite. Ukuba inkqubo yemveliso inokwenzeka kurhwebo, amazwe asentshona aya kunciphisa kakhulu ukuxhomekeka kwawo kwiintsimbi zomhlaba ezinqabileyo zase China.
I-Tetrataenite yi-alloy yentsimbi kunye ne-nickel, kunye nesakhiwo esithile se-athomu. Ixhaphakile kwiimeteorite zentsimbi kwaye ithatha izigidi zeminyaka ukwenza ngokwendalo kwindalo iphela.
Kwiminyaka yoo-1960, izazinzulu zabetha i-iron nickel alloy kunye ne-neutrons ukulungiselela iiathom ngokwesakhiwo esithile kunye ne-tetrataenite eyenziwe ngobuchule, kodwa obu bugcisa abufanelanga imveliso enkulu.
Abaphandi abavela kwiYunivesithi yaseCambridge, i-Austrian Academy of Sciences kunye neMontanuniversität eLeoben baye bafumanisa ukuba ukongeza i-phosphorus, into eqhelekileyo, kwisixa esifanelekileyo sentsimbi kunye ne-nickel, kunye nokuthululela i-alloy kwi-mold kunokuvelisa i-tetrataenite kwinqanaba elikhulu. .
Abaphandi banethemba lokusebenzisana nomkhuluabavelisi bemagnethiukufumanisa ukuba i-tetrataenite ifanelekile naiimagnethi ezisebenza kakhulu.
Imagnethi esebenza kakhulu bubuchwephesha obubalulekileyo bokwakha uqoqosho lwe-zero carbon, iindawo eziphambili zeejeneretha kunye neenjini zombane. Okwangoku, izinto ezinqabileyo zomhlaba kufuneka zongezwe ukwenza imagnethi yokusebenza ephezulu. Iimethali zomhlaba ezinqabileyo azinqabile kuqweqwe lomhlaba, kodwa inkqubo yokusulungekiswa inzima, ekufuneka itye amandla amaninzi kwaye yonakalise indalo esingqongileyo.
Unjingalwazi uGreer weSebe lezeNzululwazi ngezinto zeNzululwazi nezeMetallurgy kwiYunivesithi yaseCambridge, owayekhokela olu phando, wathi: “Kukho iindawo ezinqabileyo zomhlaba ezibekwe kwezinye iindawo, kodwa imigodi iyingozi kakhulu: kufuneka kummbiwe inani elikhulu lentsimbi ngaphambi kokuba libe lincinane. zesinyithi zomhlaba ezinqabileyo zinokukhutshwa kuzo. Phakathi kwempembelelo yokusingqongileyo kunye nokuxhomekeka okuphezulu eTshayina, kungxamisekile ukufumana ezinye izinto ezingasebenzisi zimbiwa zomhlaba ezinqabileyo. "
Okwangoku, ngaphezu kwama-80% eentsimbi ezinqabileyo zehlabathi kunyeiimagnethi zomhlaba ezinqabileyoziveliswa eTshayina. Umongameli uBiden wase-United States ukhe wavakalisa inkxaso yokunyusa imveliso yezixhobo eziphambili, ngelixa i-EU icebise ukuba amazwe angamalungu atshintshe amakhonkco awo obonelelo kwaye aphephe ukuxhomekeka okugqithisileyo e-China nakwezinye iimarike ezizimeleyo, kubandakanya isinyithi somhlaba esinqabileyo.
