I-Yttrium Oxide
I-Yttrium Oxide, ekwaziwa ngokuba yiYttria, sisixhobo esibalaseleyo sokwakha iiminerali ekudalweni kwe-spinel. Sisithako esimhlophe esiqinileyo esizinzileyo emoyeni. Sinendawo yokunyibilika ephezulu (2450oC), uzinzo lweekhemikhali, i-coefficient ephantsi yokwanda kobushushu, ukukhanya okuphezulu kokubonakalayo (70%) kunye ne-infrared (60%), amandla aphantsi okunqunyulwa kwee-photons. Ifanelekile kwiglasi, i-optic kunye nokusetyenziswa kwe-ceramic.
