摘　　要：CaCu3Ti4O1(2 CCTO)新型介电陶瓷以其高介电常数和高频率稳定性等优异性能,在高介电材料研究领域和高介电电容器领域成为关注的热点。然而,目前由于其击穿场强较小,限制了其应用范围。本文综述了最近几年国内外CCTO陶瓷击穿场强的研究进展。首先介绍了常用的CCTO陶瓷制备工艺,其次详细归纳了制备工艺和元素掺杂对其击穿场强的影响,最后总结了CCTO陶瓷击穿场强提高的规律与原因,并将其精炼为3种击穿机理。The new type CaCu3Ti4O12(CCTO)dielectric ceramic has excellent properties such as high dielectric constant and high frequency stability and becomes a hot spot in the field of high dielectric materials and high dielectric capacitors field.However,the low breakdown electric field of CCTO limits its application range.This paper summarized the research progress in breakdown field strength of CCTO ceramic inside and outside China in recent years.The common preparation process of CCTO ceramic was introduced at first,and then the effects of preparation process and element doping on its dielectric properties were summarized in detail.Finally,the law and reason for the increase of breakdown field strength of CCTO ceramics were summarized and refined into three breakdown mechanisms.
