Zirconia ceramic (Zirconium Oxide, los yog ZrO2), tseem hu ua "ceramic steel", combines siab hardness, hnav thiab corrosion kuj, thiab ib qho ntawm cov pob txha toughness siab tshaj plaws ntawm tag nrho cov ntaub ntawv ceramic.

Zirconia qib muaj ntau yam. Wintrustek muaj ob hom Zirconias uas feem ntau thov ntawm lub khw.

Magnesia-ib nrab-Stabilized Zirconia (Mg-PSZ)

Yttria-Ib nrab-Stabilized Zirconia (Y-PSZ)

Lawv txawv ntawm ib leeg los ntawm qhov xwm txheej ntawm tus neeg sawv cev stabilizing siv. Zirconia hauv nws daim ntawv purest tsis ruaj khov. Vim lawv cov pob txha tawv tawv thiab cov txheeb ze " elasticity ", Magnesia-ib feem-stabilized zirconia (Mg-PSZ) thiab yttria-ib nrab-stabilized zirconia (Y-PSZ) nthuav tawm tshwj xeeb tsis kam rau cov neeg kho tshuab shocks thiab flexural load. Ob lub zirconias no yog cov ceramics ntawm kev xaiv rau cov ntawv thov uas yuav tsum tau muaj zog txhua yam. Lwm cov qib nyob rau hauv tag nrho stabilized muaj pes tsawg leeg muaj thiab feem ntau yog siv rau high-temperature daim ntaub ntawv.

Qib feem ntau ntawm Zirconia yog Yttria Partially Stabilized Zirconia (Y-PSZ). Vim nws cov thermal expansion thiab tshwj xeeb tsis kam rau tawg propagation, nws yog ib qho khoom zoo heev rau kev koom nrog cov hlau xws li hlau.
