I-Yttrium oxide i-zirconia ezinzileyo (i-ZrO28Y2O3) yikristale ye-zirconia efakwe kwi-zirconia crystals, enokuthi yenze i-zirconia ehlanganiswe ngokupheleleyo kwiikristale ze-cubic ezizinzileyo kunye neekristale ze-monoclinic ezingazinzanga.Inokumelana nobushushu obuphezulu, ukuxhathisa ukothuka kwe-thermal kunye neempawu zokugquma.
