摘要

研究了不同工艺对压电材料PCR-62和PCR-63的微观结构特征和谐振频率温度稳定性的影响。在从热压到传统烧结的转变过程中，温度稳定性具有很高的数量级。这与陶瓷密度减小时体电荷场增大有关。

Temperature stability of resonance frequency of filter materials obtained by different techniques

The influence of the various techniques on the character of microstructure and temperature stability of resonance frequency for piezoelectric materials PCR-62 and PCR-63 has been considered. It is noted that temperature stability has high magnitudes at transition from hot pressing to traditional sintering. It is connected with an increase of field of bulk charge when the density of ceramics decreases.
