ʻO ke ʻano kemika oscandium oxide is Sc2O3, he paʻa keʻokeʻo hiki ke hoʻoheheʻe ʻia i ka wai a me ka ʻakika wela. Ma muli o ka paʻakikī o ka unuhi pololei ʻananā huahana scandiummai ka scandium i loaʻa nā minelala, ʻo ka scandium oxide ka mea i hoʻihoʻi ʻia i kēia manawa a lawe ʻia mai nā huahana o ka scandium i loaʻa nā minerale e like me ke koena ʻōpala, wai ʻōpala, uahi, a me ka ʻulaʻula.
ScandiumHe mea kemika me ka hōʻailona Sc a me ka helu ʻātoma 21. ʻO ka mea hoʻokahi he metala hoʻololi palupalu, kala-keʻokeʻo, hui pinepine megadolinium, erbium, a me nā mea ʻē aʻe, me ka liʻiliʻi loa o ka hana ʻana, a ʻo ka ʻike i loko o ka ʻōpala o ka honua ma kahi o 0.0005%. ʻO Scandium kahi huahana hoʻolālā koʻikoʻi. Ua hoʻolauna nā ʻāina i kūkulu ʻia e like me ʻEulopa a me ʻAmelika i ka paipai a me ka hoʻokaʻawale ʻana. No ka laʻana, ma ka papa inoa o nā minelala koʻikoʻi 35 i paʻi ʻia e ʻAmelika Hui Pū ʻIa, ua helu ʻia ka scandium ma ke ʻano he ʻenehana maka; ka "Alakaʻi no ka First Batch Application Demonstration of Key New Materials (2018 Edition)" i hoʻopuka ʻia e ka Ministry of Industry and Information Technology e pili ana i 3 mau mea hou e pili ana i ka scandium a me kāna mau huahana.
Scandium oxide
I kēia manawa,scandium oxideua hoʻohana nui ʻia i loko o nā alloys, nā wahie, nā mea cathode, scandium sodium halogen kukui, catalysts, activators a me nā seramika. ʻO nā alumini alumini-scandium i hana ʻia i ka scandium a me ka alumini nā mea maikaʻi o ka haʻahaʻa haʻahaʻa, ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe, ka plasticity maikaʻi, ka pale ʻana i ka corrosion a me ke kūpaʻa wela ikaika. Hoʻohana maikaʻi ʻia lākou i nā ʻāpana o nā missiles, aerospace, aviation, nā kaʻa a me nā moku. ʻO nā kukui halogen Scandium-sodium i hana ʻia mai ka scandium oxide nā mea maikaʻi o ka ʻālohilohi kiʻekiʻe, ke kala māmā maikaʻi, ka mālama mana, ke ola lōʻihi a me ka hiki ke wāwahi i ka noe. Mālama lākou i 80% ʻoi aʻe ka uila ma mua o nā kukui incandescent a me 50% ʻoi aku ka uila ma mua o nā kukui mercury. ʻO ke ola lawelawe he 5,000 a 25,000 mau hola, kahi kūpono no nā wahi o waho. Wahi a ka "2021-2026 China Scandium Oxide Industry Market In-depth Research and Development Prospects Forecast Report" i hoʻokuʻu ʻia e ka Xinshijie Industry Research Center, he kumukūʻai ka scandium oxide, ka mea e kaupalena ana i kāna noi nui. ʻO ka nui o ka mākeke honua i kēia manawa ma kahi o 400 miliona yuan.
SOFC
ʻO nā pūnaeau wahie oxide paʻa (SOFCs) he wahie i hāʻawi ʻia i waho a me ka oxidant, cathode, anode a me ka electrolyte. Ma ke ʻano he kumu ikehu maikaʻi a maʻemaʻe hoʻi, ua ʻike ʻia lākou ʻo ka ʻōmaʻomaʻo ʻōmaʻomaʻo o ke kenekulia 21. ʻO 50-70% ka hoʻololi ʻana i ka ikehu o nā pūnaewele wahie maʻamau, ʻoiai ʻo ka hoʻohana ʻana o SOFC e hoʻohana ana i ka wela a me ka ʻōnaehana mana hiki ke kiʻekiʻe e like me 80%. Hiki iā lākou ke hoʻohana ʻia e like me nā kikowaena mana paʻa i nā kahua kīwila e like me ka lako mana kikowaena nui, ka mana puʻupuʻu waena, a me ka hale liʻiliʻi i hui pū ʻia me ka wela a me ka mana. Eia kekahi, hiki ke hoʻohana ʻia e like me nā kumu mana kelepona e like me nā kumu mana moku a me nā kumu mana kaʻa kaʻa, a loaʻa nā manaʻo noi ākea.
Hiki ke hoʻohana ʻia ʻo Scandium stabilized cerium zirconium composite powder (i kapa ʻia ʻo ka pauka scandium zirconium) ma ke ʻano he mea electrolyte no nā cell fuel oxide solid (SOFC). ʻO kēia mea ka mea electrolyte i kēia manawa me ka conductivity kiʻekiʻe i hōʻike ʻia, a ua hoʻohālikelike ʻia kona conductivity ma 780 ℃ me ka YSZ ma 1000 ℃. Hiki i kēia huahana ke pani i nā mea yttria stabilized zirconia, me ka conductivity kiʻekiʻe a me ka paʻa lōʻihi, hiki ke hoʻemi i ka mahana hana o SOFC, hoʻemi i ka hoʻohana ʻana i ka ikehu, a hoʻomaikaʻi i ka hoʻololi ʻana i ka ikehu.
