摘要

采用常规固相反应法制备了K1-xNaxNbO3 (X=0.4, 0.2, 0)陶瓷(PSN)样品。用XRD对制备的样品进行了表征。所有制备的样品在室温下均呈现正交结构。研究了PSN系统在45℃~ 245℃温度范围和1MHz频率下的介电性能和电学性能。电介质常数、损耗正切和电导率随温度升高而增大。在过渡温度附近，介电常数、损耗正切和电导率随温度的变化表现出异常行为。

Synthesis, Characterization and Dielectric Properties of K 1-x Na x NbO 3

The samples of K1-xNaxNbO3 (X=0.4, 0.2, 0) ceramics (PSN) have been prepared by the conventional solid- state reaction method and sintering process. The prepared samples have been characterized by XRD. All the prepared samples show orthorhombic structure at room temperature. Dielectric and Electrical properties of PSN system have been investigated in the temperature range 45 0 C-245 0 C, and at 1MHz frequency. It is observed that dielectric constant, loss tangent and electrical conductivity increases with increasing temperature. Near the transition temperature dielectric constant, loss tangent and electrical conductivity of these samples show anomalous behaviour with temperature.
