Yttrium Oxide
Yttrium Oxide, tseem hu ua Yttria, yog ib qho khoom siv zoo heev rau kev tsim cov spinel. Nws yog ib yam khoom khov dawb uas ruaj khov rau huab cua. Nws muaj qhov kub siab (2450oC), kev ruaj khov tshuaj lom neeg, coefficient qis ntawm kev nthuav dav thermal, pob tshab rau ob qho tib si pom (70%) thiab infrared (60%) lub teeb, lub zog txiav qis ntawm photons. Nws yog qhov tsim nyog rau kev siv iav, optic thiab ceramic.
