Iyo kemikari formula yescandium oxide is Sc2O3, chitsvuku chichena chinonyungudika mumvura uye asidi inopisa. Nekuda kwekuomerwa kwekuburitsa zvakanangascandium zvigadzirwakubva ku scandium ine zvicherwa, scandium oxide parizvino inonyanya kudzoserwa uye kutorwa kubva kune-zvigadzirwa zve scandium ine zvicherwa zvakaita semarara emarara, tsvina, utsi, uye madhaka matsvuku.
Scandiumchinhu chemakemikari chine chiratidzo Sc uye nhamba yeatomu 21. Chinhu chimwe chete isimbi yakapfava, yesirivha-chena, inowanzosanganiswa ne.gadolinium, erbium, zvichingodaro, nekugadzirwa kushoma, uye zviri mugoko repasi zvinenge 0.0005%. Scandium chinhu chakakosha hurongwa chigadzirwa. Nyika dzakabudirira dzakadai seEurope neUnited States dzakaunza kurudziro yakakodzera uye kuronga. Semuenzaniso, mune rondedzero yemaminerari akakosha makumi matatu neshanu akabudiswa neUnited States, scandium yakanyorwa seyakagadzirwa mumaindasitiri; iyo "Nhungamiro yeBatch Yekutanga Chikumbiro Chiratidziro cheZvinhu Zvitsva Zvitsva (2018 Edition)" yakapihwa neBazi reIndasitiri uye Ruzivo rweTekinoroji inosanganisira zvinhu zvitatu zvitsva zvinosanganisira scandium uye zvigadzirwa zvayo.
Scandium oxide
Parizvino,scandium oxideyakashandiswa zvakanyanya mu alloys, masero emafuta, cathode zvinhu, scandium sodium halogen mwenje, catalysts, activators uye ceramics. Aluminium-scandium alloys akagadzirwa nescandium nealuminium ane zvakanakira zvepasi density, kusimba kwepamusoro, kuomarara kwepamusoro, kunaka kwepurasitiki, kushorwa kwecorrosion uye kugadzikana kwakasimba kwekupisa. Iwo anoshandiswa zvakanaka muzvikamu zvezvimiro zvezvombo zvinokandwa, aerospace, ndege, mota uye ngarava. Scandium-sodium halogen marambi akagadzirwa kubva ku scandium oxide ane zvakanakira kupenya kwakanyanya, kunaka kweruvara rwechiedza, kuchengetedza simba, hupenyu hwakareba uye mhute yakasimba yekupwanya kugona. Vanochengetedza 80% mamwe magetsi kupfuura marambi e-incandescent uye 50% mamwe magetsi kupfuura marambi emercury. Upenyu hwebasa ndeye 5,000 kusvika kumaawa 25,000, iyo inonyanya kukodzera nzvimbo dzekunze. Zvinoenderana ne "2021-2026 China Scandium Oxide Indasitiri Musika In-yakadzama Tsvagiridzo uye Development Prospects Forecast Report" yakaburitswa neXinshijie Indasitiri Research Center, scandium oxide inodhura, iyo inorambidza hukuru hwekushandisa kwayo. Ikozvino musika wepasi rose saizi ingangoita 400 miriyoni yuan.
SOFC
Solid oxide fuel cell (SOFCs) ine mafuta akapihwa kunze uye oxidant, cathode, anode uye electrolyte. Sesimba rinoshanda uye rakachena, dzinozivikanwa sebhatiri rakasvibirira rezana remakore rechi21. Iko simba rekushandura simba remafuta emafuta akawanda ari 50-70%, ukuwo kunyatsoshanda kweSOFCs uchishandisa yakasanganiswa kupisa uye simba system inogona kusvika pa80%. Inogona kushandiswa sezviteshi zvemagetsi zvakagadziriswa munzvimbo dzevagari senge hombe-yakakura yepakati magetsi, yepakati-saizi yakagovaniswa magetsi, uye imba diki yakasanganiswa kupisa uye magetsi. Pamusoro pezvo, iwo anogona zvakare kushandiswa senge nharembozha sosi semagetsi engarava uye ekufambisa magetsi masosi emotokari, uye ane tarisiro yakakura yekushandisa.
Scandium yakagadzikana cerium zirconium composite poda (inonzi scandium zirconium powder) inogona kushandiswa se electrolyte zvinhu kune yakasimba oxide mafuta masero (SOFC). Ichi chinyorwa pari zvino ndicho chinhu che electrolyte chine yakanyanya kutaurwa conductivity, uye conductivity yayo pa780 ℃ inofananidzwa neyeYSZ pa1000 ℃. Ichi chigadzirwa chinogona kutsiva zvechinyakare yttria yakagadzikana zirconia zvinhu, nepamusoro conductivity uye kugadzikana kwenguva refu, izvo zvinogona kuderedza tembiricha yekushanda yeSOFC, kuderedza kushandiswa kwesimba, uye kuvandudza simba rekushandura simba.
