Abstract: Zirconia (ZrO₂ ) ceramics have been widely used and concerned by many researchers because of their light texture , corrosion resistance，high temperature resistance and excellent mechanical proper-ties. In this paper，the research status of progress of phase transformation and stabilization of ZrO₂ ceramics at home and abroad in recent years is reviewed and the effect of adding stabilizers on the properties of ZrO₂ ceramics is summarized and the preparation method and technology ,doping modification，phase transformation toughening of ZrO₂，ceramics are discussed，and the future research direction of phase transformation stabilization of ZrO₂ ceramics is prospected.

Key words: ZrO₂ ceramics, martensitic transformation, phase transformation toughening, dopitng stabilization
