dc.description.abstract本论文采用固相法制备CaCu3Ti4O12(简写为CCTO)陶瓷,研究了添加剂含量及成型工艺对CCTO陶瓷致密度、微观结构及电气性能等方面的影响。 首先分别以Na0.5Bi0.5Cu3Ti4O12(简写为NBCTO)、Bi0.667Cu3Ti4O12(简写为BCTO)为单一添加剂,CuO-TiO2-La2O3(简写为Cu/Ti/La)为复合添加剂,采用干压成型法制备CCTO块体陶瓷。实验结果表明:当NBCTO含量为5%时,陶瓷形成具有明显立方晶粒的单一钙钛矿结构CCTO基陶瓷,此时陶瓷的电容率达到最大值ℰr=696770(1kHz),对应的介电损耗为tanδ=0.526,非线性系...
dc.description.abstractIn this thesis, Ceramics CaCu3Ti4O12, i.e., CCTO, were prepared by the conventional solid-state reaction. The effects of forming technique and amount of different dopants on chemical structure, dielectric properties and J-E response of the samples were studied. Firstly, Na0.5Bi0.5Cu3Ti4O12, i.e., NBCTO, and Bi0.667Cu3Ti4O12, i.e., BCTO, were chosen as single additives, respectively, and, CuO-TiO2...
