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.
Isi njirimara nke akụkụ seramiiki zirconia:
1. Mgbochi na-eyi nke ọma, dị elu 276 ugboro karịa igwe anaghị agba nchara
2. Njupụta dị elu karịa ọtụtụ ceramics teknụzụ, karịa 6 g / cm3
3. Isi ike dị elu, karịa 1300 MPa maka Vicker
4. Nwere ike idi elu okpomọkụ ruo 2400 °
5. Igwe ọkụ ọkụ dị ala, ihe na-erughị 3 W / mk na ụlọ okpomọkụ
6. Oyiri ọnụọgụ nke mgbasawanye ọkụ dị ka igwe anaghị agba nchara
7. Ike mgbawa pụrụiche ruru 8 Mpa m1/2
8. Chemical inertness, ịka nká na-eguzogide, na ọ bụghị nchara ruo mgbe ebighị ebi
9. Nguzogide ọla ndị a wụrụ awụ n'ihi ebe mgbaze pụrụiche.
