  dielectric
Because of the existence of nanopores, the dielectric constant of PI films decreased by a wide margin and was less than 2.0 at a PU mass fraction of 20%.
      
It implies that this is an effective means to reduce the dielectric constant of PI, but it also causes the decrease of tensile strength and the rise of water absorption.
      
Lead zirconium titanate (PZT) films (Zr/Ti=45:55) with a high dielectric constant are prepared successfully on the low-resistance Si substrate in sol-gel dip-coating process with PT film used as the buffer layer.
      
The dielectric and ferroelectric properties of the films as well as the relationship between crystallization and preparing condition are studied.
      
The relative dielectric constant εr and the dissipation factor tgδ of the PZT thin films were measured with an LCR meter and were found to be 158 and 0.04-0.005, respectively.

Dielectric and piezoelectric properties of pure lead titinate-zirconate piezoelectric ceramics (PZT) with compositions close to the morphotropic phase boundary have been studied within the temperature range 4.2 to 300K; It is shown that the dielectric and piezoelectric activeness are sharply peaked at the compositions very close to the morphotropic phase boundary, and there are at least two relaxation processes contributing to dielectric and piezoelectric properties. The possible mechanism of the processes is described and the anomaly occurring on T33-r curve near 150K of the 50/50 composition is discussed.

在4.2至300K的低温范围内对组分邻近于准同型相界的纯钛锆酸铅压电陶瓷(PZT)的介电性质和压电性质进行了实验研究.结果表明,组分紧靠准同型相界的PZT具有最大的介电和压电活性.结果还表明,至少有两个弛豫过程对纯PZT的介电性质和压电性质有所影响.文中指出了导致这些弛豫过程的可能机制,讨论了50/50组分在其ε_(33)~T-T曲线上于150K附近出现的拐变现象.

The key problem in ceramic sintering is the atom diffusion or mobility. Proper dopant helps promote defect forming during sintering. It is reported that for KTaO3 ceramics, in which MgO is used as a sintering aid, excellent grain growth and mi-crostructure can be obtained by conventional sintering method. Tests on the dielectric properties within the temperature range 4.2 to 540K show that they are different from those of pure KTaO3 ceramics.

陶瓷烧结的关键问题,是原子的扩散和迁移,适当的掺杂物在陶瓷烧结过程中能促进缺陷的形成.本文报导以MgO为矿化剂掺杂KTaO_3陶瓷的研究结果.用常规的烧结方法获得了良好的晶粒生长及微结构.在4.2—540K的温度范围内测量了介电系数及介电损耗,发现了一些不同于纯KTaO_3陶瓷的结果.
