Ndi chiyaniScandium oxidekugwiritsidwa ntchito?
Scandium oxideScandia, yomwe imatchedwanso Scandia, imagwiritsa ntchito kwambiri m'mafakitale ambiri chifukwa cha mawonekedwe ake apadera a physico-chemical. Ndizinthu zopangira ma alloys a Al-Sc, omwe amagwiritsa ntchito magalimoto, zombo ndi zakuthambo. Ndiwoyenera chigawo chachikulu cha UV, AR ndi zokutira za bandpass chifukwa cha mtengo wake wapamwamba, kuwonekera, ndi kuuma kosanjikiza kumapangitsa kuti pakhale kuwonongeka kwakukulu kwanenedwa kuti kuphatikizidwe ndi silicon dioxide kapena magnesium fluoride kuti igwiritsidwe ntchito mu AR. Scandium oxide imagwiritsidwanso ntchito mu zokutira zowoneka bwino, chothandizira, zida zamagetsi zamagetsi ndi mafakitale a laser. Amagwiritsidwanso ntchito chaka chilichonse popanga nyali zotulutsa mphamvu kwambiri. Cholimba choyera chosungunuka kwambiri chomwe chimagwiritsidwa ntchito m'makina otentha kwambiri (chifukwa cha kukana kutentha ndi kutenthedwa kwa kutentha), zida zamagetsi zamagetsi, ndi magalasi.
