ʻOkiuma Yttrium
ʻOkiuma Yttrium, i ʻike ʻia hoʻi ʻo Yttria, he mea mineralizing maikaʻi loa no ka hoʻokumu ʻana o ka spinel. He mea paʻa keʻokeʻo paʻa i ka ea. Loaʻa iā ia kahi kiko heheʻe kiʻekiʻe (2450oC), kūpaʻa kemika, coefficient haʻahaʻa o ka hoʻonui wela, transparency kiʻekiʻe no ka ʻike ʻia (70%) a me ka infrared (60%) kukui, ikehu ʻoki haʻahaʻa o nā photons. He kūpono ia no nā noi aniani, optic a me ceramic.
