Zirconia ceramic (Zirconium Oxide, kana ZrO2), inozivikanwawo se "ceramic steel", inobatanidza kuomarara kwakakwirira, kusakara nekuora, uye imwe yemhando yepamusoro-soro yekutsiga kusimba pakati pezvinhu zvese zveceramic.

Zirconia mamakisi akasiyana. Wintrustek inopa marudzi maviri eZirconias anonyanya kukumbirwa pamusika.

Magnesia-Pachikamu-Yakadzikama Zirconia (Mg-PSZ)

Yttria-Pachikamu-Yakadzikama Zirconia (Y-PSZ)

Ivo vanosiyaniswa kubva kune mumwe kune hunhu hweiyo inodzikamisa agent inoshandiswa. Zirconia mune yayo yakachena fomu haina kugadzikana. Nekuda kwekusimba kwavo kwekutyoka uye hukama " elasticity ", Magnesia-partially-stabilized zirconia (Mg-PSZ) uye yttria-partially-stabilized zirconia (Y-PSZ) inoratidzira kupikisa kunoshamisa kune mechanical shocks uye flexural load. Aya maviri zirconias ndiwo maceramics esarudzo kune maapplication anoda yakanyanyisa mechani simba. Mamwe magiredhi mune yakagadzikana zvizere kuumbwa aripo uye anonyanya kushandiswa kune yakakwirira-tembiricha maapplication.

Giredhi rakajairika reZirconia ndiYttria Partially Stabilized Zirconia (Y-PSZ). Nekuda kwekuwedzera kwayo kupisa kwemafuta uye kusarudzika kuramba kupararira, chinhu chakanakisa chekubatanidza nesimbi sesimbi.
