Yatrium oxide
Yatrium oxide, wanda kuma aka sani da Yttria, kyakkyawan wakili ne na ma'adinai don samuwar kashin baya. Abu ne mai tsayayye, fari mai ƙarfi. Yana da babban ma'aunin narkewa (2450oC), kwanciyar hankali na sinadarai, ƙarancin haɓakar haɓakar thermal, babban nuna gaskiya ga duka bayyane (70%) da hasken infrared (60%), ƙarancin yanke makamashi na photons. Ya dace da aikace-aikacen gilashi, gani da yumbu.
