CaCu3Ti4O12陶瓷的介电特性与弛豫机理OA北大核心CSCDCSTPCD
Dielectric property and relaxation mechanism of CaCu3Ti4O12 ceramic∗
本文采用Novocontrol宽频介电谱仪在−100◦C—100◦C温度范围内、0.1 Hz—10 MHz频率范围内测量了表面层打磨前后CaCu3Ti4O12陶瓷的介电特性，分析了CaCu3Ti4O12陶瓷的介电弛豫机理.首先，基于对宏观“壳-心”结构的定量分析，排除了巨介电常数起源于表面层效应的可能性；其次，基于经典Maxwell-Wagner夹层极化及其活化能物理本质的分析，排除了巨介电常数起源于经典Maxwell-Wagner极化的可能…查看全部>>
In this paper, the dielectric property of CaCu3Ti4O12 ceramic is measured by Novocontrol wide band dielectric spectrometer in a temperature range of−100–100 ◦C and frequency range of 0.1 Hz–10 MHz, and the corresponding dielectric relaxation mechanism is discussed. Firstly, on the basis of quantitative analysis of macroscopic shell-core structure, the possibility of colossal dielectric constant (CDC) originating from the surface insulated layer…查看全部>>
