Zirconia bụ ihe nwere ike ọrụ dị elu yana mgbaji siri ike na ụlọ okpomọkụ. A na-agbakwunye zirconia anyị (ZrO2) na 3mol% Y2O3 partial stable zirconia (PSZ). N'ihi na urughuru dayameta nke PSZ ihe bụ obere, ọ nwere ike esichara na elu nkenke, na ngwa ya na nkenke machining akụkụ dị ka ebu na-agbasawanye. Tụkwasị na nke ahụ, a pụkwara iji ya maka ngwá ọrụ mmepụta ihe, akụkụ njikọ ngwa anya na ikpochapụ ngwá ọrụ. Enwere ike iji ike mgbaji dị elu nke PSZ mee isi iyi pụrụ iche, a na-ejikwa ya na mma seramiiki ụlọ, slicer na akụkụ ndị ọzọ.
