Thermal properties, chemical stability of ZrO2 and their mechanisms are reviewed.The ultra-low thermal con-ducting coefficient of ZrO2 is the key for its application in thermal barrier coatings , the structure and synthesis methodology are introduced, and advantages of ZrO2 based thermal barrier coatings are described.The surface energy, acidic positions and their originations in ZrO2 , the principle, nature, preparation and application areas of ZrO2 based super-acids are ana-lyzed.The fairly good chemical stability of ZrO2 is the basic for catalytic application.ZrO2 based catalysts can be classi-fied into pure ZrO2 , loaded and composite ones.The composites-based ZrO2 has better catalytic performance and some typical catalytic reactions are also listed.Mechanisms and research progress of CeO2 -ZrO2 solid solutions as three way catalysts are also introduced.This review provides the systematic knowledge of thermal and catalytic applications of ZrO 2 , which can help understanding their mechanisms and surface properties .
