Scandium oxide
Hajoale,scandium oxidee 'nile ea sebelisoa haholo ho li-alloys, lisele tsa mafura, lisebelisoa tsa cathode, mabone a scandium sodium halogen, li-catalysts, activators le ceramics. Li-alloys tsa aluminium-scandium tse entsoeng ka scandium le aluminium li na le melemo ea ho fokotseha ho fokolang, matla a phahameng, boima bo phahameng, polasetiki e ntle, ho hanyetsa kutu le botsitso bo matla ba mocheso. Li sebelisoa hantle likarolong tsa sebopeho sa metsu, sefofane, sefofane, likoloi le likepe. Mabone a scandium-sodium halogen a entsoeng ka scandium oxide a na le melemo ea khanya e phahameng, 'mala o motle o khanyang, ho boloka matla, bophelo bo bolelele le bokhoni bo matla ba ho senya moholi. Ba boloka motlakase o fetang 80% ho feta mabone a incandescent le motlakase o fetang 50% ho feta mabone a mercury. Bophelo ba ts'ebeletso ke lihora tse 5,000 ho isa ho tse 25,000, tse loketseng haholo libaka tsa kantle. Ho ea ka "2021-2026 China Scandium Oxide Industry In-Depth Research and Development Prospects Report" e lokollotsoeng ke Xinshijie Industry Research Center, scandium oxide e theko e boima, e thibelang ts'ebeliso ea eona e kholo. Boholo ba 'maraka oa lefatše ha joale bo ka ba li-yuan tse limilione tse 400.
SOFC
Solid oxide fuel cell (SOFCs) e na le mafura a fanoeng ka ntle le oxidant, cathode, anode le electrolyte. E le mohloli oa matla o sebetsang hantle le o hloekileng, li tsejoa e le betri e tala ea lekholong la bo21 la lilemo. Matla a ho fetola matla a lisele tsa mafura ka kakaretso ke 50-70%, ha ts'ebetso e felletseng ea li-SOFC tse sebelisang mocheso o kopaneng le sistimi ea matla e ka ba holimo ho 80%. Li ka sebelisoa e le liteishene tsa motlakase tse tsitsitseng libakeng tsa sechaba joalo ka phepelo ea motlakase e bohareng, phepelo ea matla a mahareng, le mocheso o kopaneng oa malapa le phepelo ea motlakase.
