    Yttrium oxide

    Yttrium oxide, yomwe imadziwikanso kuti Yttria, ndi mchere wabwino kwambiri wopangira msana. Ndi chinthu chosasunthika, cholimba choyera. Ili ndi malo osungunuka kwambiri (2450oC), kukhazikika kwa mankhwala, kutsika kwa mphamvu zowonjezera kutentha, kuwonetseredwa kwakukulu kwa zonse zowoneka (70%) ndi kuwala kwa infrared (60%), kutsika kochepa mphamvu ya photons. Ndizoyenera kugwiritsa ntchito magalasi, optic ndi ceramic.
