Scandium oxide, ka mokhoa oa lik'hemik'haleSc2O3, ke ntho e thata e tšoeu e qhibilihang metsing le asiti e chesang. Ka lebaka la bothata ba ho ntša lihlahisoa tsa scandium ka ho toba ho scandium e nang le liminerale, scandium oxide hajoale e fumanoa haholo-holo 'me e ntšoa lihlahisoa tsa scandium tse nang le liminerale tse kang masala a litšila, metsi a litšila, mosi le seretse se sefubelu.
Lihlahisoa tsa maano
Scandiumke sehlahisoa sa bohlokoa sa leano. Pejana, Lefapha la Litaba tsa ka Hare la United States le ile la phatlalatsa lethathamo la liminerale tse 35 tsa maano (liminerale tse bohlokoa) tse nkoang e le tsa bohlokoa moruong oa US le ts'ireletso ea naha (Lethathamo la ho Qetela la Liminerale Tse Bohlokoa 2018). Hoo e ka bang liminerale tsohle tsa moruo li kenyelelitsoe, joalo ka aluminium e sebelisoang indastering, tšepe ea sehlopha sa platinum e sebelisoang tlhahisong ea li-catalyst, likarolo tse sa tloaelehang tsa lefats'e tse sebelisoang lihlahisoa tsa elektroniki, tin le titanium tse sebelisoang tlhahiso ea alloy, jj.
Tšebeliso ea Scandium oxide
Hangata scandium e le 'ngoe e sebelisoa ka li-alloys, 'me scandium oxide e boetse e phetha karolo ea bohlokoa linthong tsa ceramic. Ka mohlala, lisebelisoa tsa ceramic tsa tetragonal zirconia tse ka sebelisoang e le lisebelisoa tsa electrode bakeng sa lisele tse matla tsa oxide li na le thepa e khethehileng haholo. The conductivity ea electrolyte ena e eketseha ka ho eketseha ha mocheso le moea oa oksijene tikolohong. Leha ho le joalo, mohaho oa kristale oa thepa ena ea ceramic ka boeona e ke ke ea e-ba teng ka mokhoa o tsitsitseng ebile ha e na boleng ba indasteri; e tlameha ho kenngoa ka lintho tse ling tse ka lokisang mohaho ona e le ho boloka thepa ea pele. Ho eketsa 6-10% ea scandium oxide ho tšoana le mohaho oa konkreite, o lumellang scandium oxide ho tsitsisoa holim'a letlapa la lisekoere.
Scandium oxide e ka boela ea sebelisoa e le densifier le stabilizer bakeng sa matla a phahameng, a phahameng a mocheso a sa keneleng mocheso oa thepa ea ceramic ea silicon nitride. E ka hlahisa karolo ea refractory Sc2Si2O7 moeling oa likaroloana tse ntle, kahoo e fokotsa ho senyeha ha mocheso o phahameng oa lirafshoa tsa boenjiniere. Ha ho bapisoa le ho eketsa li-oxide tse ling, e ka ntlafatsa boleng bo phahameng ba mocheso oa mocheso oasilicon nitride. Ho eketsa palo e nyane ea Sc2O3 ho UO2 ka har'a mafura a nyutlelie a mocheso o phahameng ho ka qoba phetoho ea lattice, keketseho ea molumo le mapetsong a bakoang ke phetoho ea UO2 ho ea ho U3O8.
Scandium oxide e ka sebelisoa e le sesebelisoa sa mouoane bakeng sa liphahlo tsa semiconductor. Scandium oxide e ka boela ea sebelisoa ho etsa li-laser tse tiileng-wavelength solid-state, lithunya tsa elektronike tsa thelevishene tse nang le tlhaloso e phahameng, mabone a tšepe halide, joalo-joalo.
Tlhahlobo ea Indasteri
Lilemong tsa morao tjena, scandium oxide e hohetse tlhokomelo e eketsehileng tšimong ea lisele tse mafura tsa oxide tsa malapeng (SOFC) le mabone a scandium sodium halogen. SOFC e na le melemo ea ts'ebetso e phahameng ea tlhahiso ea matla, ts'ebetso e phahameng ea ho kopanya, paballo ea mehloli ea metsi, ts'ireletso ea tikoloho e tala, kopano e bonolo ea modular, le mefuta e mengata ea khetho ea mafura. E na le boleng bo boholo ba ts'ebeliso libakeng tsa phepelo ea motlakase e ajoang, libeteri tsa motlakase oa likoloi, libeteri tsa polokelo ea matla, joalo-joalo.
