Ko te Scandium oxide he whanui te tono - he tino pai mo te whanaketanga i roto i te mara SOFC

Te tātai matū oscandium waikura is Sc2O3, he totoka ma e memeha ana ki te wai me te waikawa wera. Na te uaua o te tango tikahua scandiummai i te scandium kei roto kohuke, ko te scandium oxide te nuinga o tenei wa ka whakahokia mai, ka tangohia mai i nga hua o te scandium kei roto kohuke penei i te toenga para, te wai para, te paowa, me te paru whero.

Scandiumhe huānga matū me te tohu Sc me te tau ngota 21. Ko te matū kotahi he whakarewa ngohe, he hiriwa-ma te whakawhiti, he maha tonu te konatunatua ki tegadolinium, erbium, me etahi atu, he iti rawa te hanga, me te mea kei roto i te kirinuku o te whenua kei te 0.0005%. Ko Scandium tetahi hua rautaki nui. Ko nga whenua whakawhanake pera i a Uropi me te United States kua whakauru mai i te akiaki me te tohatoha. Hei tauira, i roto i te rarangi o nga kohuke matua 35 i whakaputaina e te United States, kua whakarārangihia te scandium hei rauemi mata ahumahi; ko te "Aratatohu mo te Whakaaturanga Taupānga Tuatahi o nga Rawa Hou Matua (2018 Edition)" i tukuna e te Manatu Ahumahi me te Hangarau Paarongo e toru nga rauemi hou e pa ana ki te scandium me ona hua.

Scandium waikura

I tenei wa,scandium waikurakua whakamahia whānuitia i roto i te koranu, pūtau wahie, rauemi cathode, scandium konutai halogen rama, whakakōkī, activators me uku. Ko nga konumohe konumohe-scandium i hangaia mai i te scandium me te konumohe he painga o te iti kiato, te kaha teitei, te pakeke teitei, te kirihou pai, te aukati waikura me te kaha o te waiariki. He pai te whakamahi i roto i nga waahanga hanganga o nga missiles, aerospace, rererangi, motuka me nga kaipuke. Ko nga rama halogen Scandium-sodium i hangaia mai i te scandium oxide he painga o te kanapa teitei, te tae marama pai, te whakaora hiko, te roa o te ora me te kaha pakaru o te kohu. E 80 paiheneti te nui ake o te hiko ka tiakina e ratou i nga rama kanapa me te 50% te nui ake o te hiko i nga rama mercury. Ko te oranga ratonga ko te 5,000 ki te 25,000 haora, he mea tino pai mo nga waahi o waho. E ai ki te "2021-2026 China Scandium Oxide Industry Market In-depth Research and Development Prospects Forecast Report" i tukuna e te Xinshijie Industry Research Center, he utu nui te scandium oxide, e aukati ana i tana tono nui. Ko te rahi o te maakete o te ao o naianei kei te 400 miriona yuan.

SOFC

Ko nga pūtau wahie waikura totoka (SOFCs) kei roto ko te wahie me te hāora, cathode, anode me te electrolyte. Hei puna hiko pai me te ma, e mohiotia ana ko te pākahiko matomato o te rautau 21. Ko te kaha o te hurihanga kaha o nga pūtau wahie whanui ko te 50-70%, ko te kaha matawhānui o nga SOFC ma te whakamahi i te wera me te punaha hiko ka eke ki te 80%. Ka taea te whakamahi hei teihana hiko pumau i roto i nga mara a-iwi penei i te toha hiko nui-nui-a-roto, te toha hiko tohatoha reo-rahi, me te whare iti te wera me te hiko hiko. I tua atu, ka taea hoki te whakamahi hei puna hiko pūkoro penei i nga puna hiko kaipuke me nga puna hiko waka kawe, me te whai waahi nui ki te tono.

Ka taea te whakamahi i te paura hiato cerium zirconium Scandium (e kiia ana ko te paura scandium zirconium) hei rauemi electrolyte mo nga pūtau wahie waikura totoka (SOFC). Ko tenei rawa te rauemi electrolyte i tenei wa me te kaha o te kawe korero, a, ko tona kawe i te 780 ℃ he rite ki te YSZ i te 1000 ℃. Ka taea e tenei hua te whakakapi i nga taonga zirconia yttria tuku iho, me te kaha ake o te kawe me te pumau mo te wa roa, ka taea te whakaiti i te pāmahana whakahaere o te SOFC, te whakaiti i te whakapau kaha, me te whakapai ake i te kaha o te hurihanga.
