I-Yttrium Oxide
I-Yttrium Oxide, eyaziwa nangokuthi i-Yttria, iyi-ejenti enhle kakhulu yokwakheka kwe-spinel. Iyinto eqinile emhlophe eqinile futhi eqinile emoyeni. Inezinga lokuncibilika eliphezulu (2450oC), ukuqina kwamakhemikhali, i-coefficient ephansi yokwanda kokushisa, ukukhanya okuphezulu kokubili kokukhanya okubonakalayo (70%) kanye ne-infrared (60%), amandla aphansi okunqunywa kwama-photon. Ifanele ukusetshenziswa kwengilazi, i-optic kanye ne-ceramic.
