- 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。 - On the base of tg - dta , found the yb : kgw crystal has very good thermal stability under 1100 , which has two obvious absorption peak at 1088 and 1025 , contrast with the pure kgw crystal ( melting point at 1005 , phase transition temperature from tetragonal system to monoclinic is 1075 ) , we know the yb : kgw crystal ' s melting point is the absorption peak at 1088 , phase transition peak from tetragonal system to monoclinic is the absorption peak at 1025
利用tg - dta对所生长的yb ： kgw晶体测定说明，其在1100以下的热稳定性是很好的。 yb ： kgw晶体在1088和1025有两个明显的吸收峰，判断在1088处较宽的吸收峰是yb ： kgw晶体的熔点， 1025处的吸收峰是yb ： kgw晶体从四方晶系向单斜晶系的相转变峰。
