摘　　要：CaCu3Ti4O12(CCTO)介电陶瓷材料以其高介电常数、高热稳定性和强烈的非线性等优异性能,在科学研究和实际应用中成为当前介电材料领域研究的热点。本文综述了迄今为止介电常数最高的CCTO钙钛矿体系介电陶瓷材料的相关进展,介绍了几种制备方法,评述了CCTO高介电陶瓷的掺杂改性和复合的研究现状,并对其发展趋势作了展望。CaCu3Ti4O12 （CCTO） dielectric ceramic have been attracting great attention worldwide from the viewpoint of higher dielectric constant, thermal stability and nonlinear behaviours. In this paper, the high dielectric ceramic of CCTO ceramic in perovskite structure are summarized and the recent progresses of the ceramics are generally reviewed. It is pointed out that doping modification and compound of CCTO ceramics are being widely studied internationally, prepareation technique and dielectric properties analysis are also summarized. Finally, it is noted that the CCTO high dielectric ceramics are potential candidates.
