Scandium oxide, ndi formula ya mankhwalaChithunzi cha Sc2O3, ndi cholimba choyera chomwe chimasungunuka m'madzi ndi asidi otentha. Chifukwa chovuta kutulutsa mwachindunji zinthu za scandium kuchokera ku scandium yomwe ili ndi mchere, scandium oxide pakadali pano imapezeka makamaka ndikuchotsedwa muzinthu za scandium zomwe zimakhala ndi mchere monga zotsalira za zinyalala, madzi oyipa, utsi, ndi matope ofiira.
Zogulitsa za Strategic
Scandiumndi yofunika njira mankhwala. M'mbuyomu, Dipatimenti ya Zam'kati ku US idasindikiza mndandanda wa 35 strategic minerals (minerals yovuta) yomwe imawonedwa kuti ndi yofunika kwambiri pachuma cha US ndi chitetezo cha dziko (Final List of Critical Minerals 2018). Pafupifupi mchere wonse wachuma umaphatikizidwa, monga aluminiyumu yomwe imagwiritsidwa ntchito m'makampani, zitsulo zamagulu a platinamu zomwe zimagwiritsidwa ntchito popanga zopangira, zinthu zapadziko lapansi zomwe zimagwiritsidwa ntchito pamagetsi, malata ndi titaniyamu zomwe zimagwiritsidwa ntchito popanga aloyi, ndi zina zambiri.
Kugwiritsa ntchito Scandium oxide
Single scandium nthawi zambiri imagwiritsidwa ntchito mu alloys, ndipo scandium oxide imagwiranso ntchito yofunika kwambiri mu zida za ceramic. Mwachitsanzo, tetragonal zirconia ceramic zipangizo zimene angagwiritsidwe ntchito ngati elekitirodi zipangizo olimba okusayidi mafuta maselo ndi katundu wapadera kwambiri. Ma conductivity a electrolyte awa amawonjezeka ndi kuwonjezereka kwa kutentha ndi mpweya wa okosijeni m'chilengedwe. Komabe, mawonekedwe a kristalo a zinthu za ceramic izi sizingakhalepo mokhazikika ndipo alibe phindu la mafakitale; iyenera kupangidwa ndi zinthu zina zomwe zingathe kukonza dongosololi kuti likhalebe ndi katundu woyambirira. Kuonjezera 6-10% ya scandium oxide kuli ngati konkire, kulola kuti scandium oxide ikhazikike pamtunda wa lattice.
Scandium okusayidi itha kugwiritsidwanso ntchito ngati densifier ndi stabilizer kwa mkulu-mphamvu, mkulu-kutentha zosagwira engineering ceramic zinthu silicon nitride. Iwo akhoza kupanga refractory gawo Sc2Si2O7 m'mphepete mwa particles zabwino, potero kuchepetsa mkulu-kutentha mapindikidwe wa zomangamanga zadothi. Poyerekeza ndi kuwonjezera oxides ena, izo zikhoza kusintha mkulu-kutentha makina katundu wasilicon nitride. Kuwonjezera pang'ono Sc2O3 kuti UO2 mu mkulu-kutentha riyakitala mafuta nyukiliya angapewe kusintha lattice, kuchuluka kwa voliyumu ndi ming'alu chifukwa cha kusintha kwa UO2 kuti U3O8.
Scandium okusayidi angagwiritsidwe ntchito ngati evaporation zinthu zokutira semiconductor. Scandium okusayidi itha kugwiritsidwanso ntchito kupanga ma lasers osinthasintha-wavelength solid-state, matanthauzo apamwamba amfuti zama elekitironi pawayilesi, nyali zachitsulo za halide, ndi zina zambiri.
Kusanthula Kwamakampani
M'zaka zaposachedwa, scandium oxide yakopa chidwi chochulukirapo m'maselo amafuta olimba a oxide (SOFC) ndi nyali za scandium sodium halogen. SOFC ili ndi maubwino opangira mphamvu zamagetsi, kuphatikizika kwakukulu, kusungirako madzi, kuteteza zachilengedwe zobiriwira, kusonkhana kosavuta, komanso kusankha mafuta osiyanasiyana. Ili ndi phindu lalikulu la ntchito m'magawo ogawa magetsi, mabatire amagetsi amagetsi, mabatire osungira mphamvu, ndi zina zambiri.
