三元系压电陶瓷 meaning in Chinese
ternary system piezoelectric ceramics
Examples
- The influence that the zr / ti ratios have on the ceramic crystal structure and its properties are studied through the research carried out about the relative respects of the fabricated samples . the increase of zr / ti ratio can result in the crystal structure transformation from the tetragonal to the rhombohedral , it can also induce the weakness in the stability of the ceramic crystal structure , for example , the drop in the curie temperature . in order to enhance the relative low mechanical quality factor of pzn - pzt system piezoceramics , component addition pb ( mn1 / 3sb2 / 3 ) o3 ( hereafter abbreviated as pms ) are introduced in to form a new psudo - tetragonal system ceramics
为获得具有高的机电耦合系数kp ,高的机械品质因数qm的高性能压电陶瓷,采用二次合成法制备了不同zr ti比的铌锌酸铅-锆钛酸铅基( pzn - pzt )三元系压电陶瓷材料,研究了zr ti比变化对陶瓷结构和性能的影响规律,发现zr ti比增大除了可以使陶瓷的相结构由四方相向三方相转化外,还降低了陶瓷的结构的稳定性,使tc温度下降。
