摘要: 氧化铈稳定的四方氧化锆多晶陶瓷(Ce-TZP)具有良好的抗低温老化性和很高的断裂韧性(KIC>20 MPa·m1/2),但是弯曲强度较低(500 MPa左右)。如何在保留Ce-TZP陶瓷的抗低温老化性和高断裂韧性的同时,提高其强度,是本领域研究人员共同关心的问题。大量研究表明,通过添加其他固溶离子(如Y3+)达到共稳定效果和引入第二相(如Al2O3)获得细晶Ce-TZP基的复相陶瓷,可以显著提高材料的断裂强度,综合改善其力学性能。本文对CeO2与其他氧化物共稳定的ZrO2陶瓷及Ce-TZP/Al2O3复相陶瓷的研究进展进行了综述,并以义齿种植和增材制造为例介绍了其应用现状。

Abstract: Ceria-stabilized tetragonal zirconia polycrystalline ceramics (Ce-TZP) have excellent low temperature degradation (LTD) resistance and high fracture toughness (KIC>20 MPa·m1/2). However, its application has been limited by the low flexual strength (~500 MPa). How to improve the strength of Ce-TZP ceramics while retaining their LTD resistance and high fracture toughness is a common concern. As revealed by large amounts of research works, by adding other solutes (such as Y3+) for co-stabilization and introducing an immiscible second phase (such as Al2O3) for grain refinement, the flexural strength of Ce-TZP ceramics can be improved significantly, and their mechanical properties can be comprehensively improved. In this paper, the research progress of ZrO2 co-stabilized by CeO2 and other oxides, and Ce-TZP/Al2O3 composite ceramics was reviewed, and their applications were introduced by taking dental implant and additive manufacturing as examples.

Key words: co-stabilized ceramic, Ce-TZP/Al2O3 composite ceramic, mechanical property, implant supported denture, additive manufacturing
