I-Scandium oxide

Incazelo emfushane:

I-Scandium(III) Oxide noma i-scandia iyinhlanganisela yezinto ezingaphili nefomula ethi Sc2O3.Ukubukeka kuyimpushana emhlophe enhle ye-cubic system.Inezinkulumo ezehlukene njenge-scandium trioxide, i-scandium(III) oxide ne-scandium sesquioxide.Izakhiwo zayo ze-physico-chemical zisondelene kakhulu namanye ama-oxides avela emhlabeni afana ne-La2O3, Y2O3 kanye ne-Lu2O3.Ingenye yama-oxide amaningana ezakhi zomhlaba ezingavamile ezinephuzu eliphezulu lokuncibilika.Ngokusekelwe kubuchwepheshe bamanje, i-Sc2O3/TREO ingaba ngu-99.999% phezulu.Iyancibilika ku-asidi eshisayo, nokho ayincibiliki emanzini.

YiniI-Scandium oxideusetshenziselwe?

I-Scandium oxide, ebizwa nangokuthi i-Scandia, ithola ukusetshenziswa okubanzi ezimbonini eziningi ngenxa yezakhiwo zayo ezikhethekile ze-physico-chemical.Kuyimpahla engasetshenzisiwe yama-alloys e-Al-Sc, asetshenziselwa izimoto, imikhumbi kanye ne-aerospace.Ifanele ingxenye yenkomba ephezulu ye-UV, AR kanye ne-bandpass coatings ngenxa yenani layo eliphezulu lenkomba, ukukhanya, kanye nokuqina kongqimba kwenza umonakalo omkhulu ubikwe ngezinhlanganisela ne-silicon dioxide noma i-magnesium fluoride ukuze isetshenziswe ku-AR.I-Scandium Oxide nayo isetshenziswa embotsheni ye-optical, i-catalyst, i-ceramics kagesi kanye nemboni ye-laser.Ibuye isetshenziswe minyaka yonke ekwenzeni amalambu akhipha amandla aphezulu.Okuqinile okumhlophe okuncibilika okuphezulu okusetshenziselwa amasistimu okushisa okuphezulu (ngokumelana kwawo nokushisa nokushaqeka okushisayo), izinto zobumba zikagesi, nokwakheka kwengilazi.
