Tsis zoo li cov tsoos ceramics uas zoo li nyuaj thiab nkig, Zirconia muaj lub zog siab, hnav tsis kam, thiab yoog raws ntau dua li lwm cov khoom siv ceramics.Zirconia yog cov khoom siv hluav taws xob muaj zog heev nrog cov khoom zoo hauv hardness, tawg toughness, thiab corrosion kuj;tag nrho tsis muaj cov cuab yeej zoo tshaj plaws ntawm ceramics - siab brittleness.
Muaj ntau ntau qib ntawm Zirconia muaj, feem ntau ntawm cov uas yog Yttria Partially Stabilized Zirconia (Y-PSZ) thiab Magnesia Partially Stabilized Zirconia (Mg-PSZ).Ob qho ntawm cov ntaub ntawv no muaj cov khoom zoo heev, txawm li cas los xij, qhov chaw ua haujlwm thiab ib feem geometry yuav txiav txim siab seb qib twg yuav tsim nyog rau cov ntawv thov tshwj xeeb (ntxiv rau qhov no hauv qab no).Nws qhov tshwj xeeb tsis kam ua kom tawg tawm thiab kev nthuav dav thermal ua rau nws yog ib qho khoom siv zoo heev rau kev koom nrog ceramics nrog hlau xws li hlau.Vim Zirconia cov khoom tshwj xeeb nws qee zaum hu ua "ceramic steel".
General Zirconia Properties
