Effect of PbO Concentration on the Templated Grain Growth of PMN-32.5PT Ceramics

摘要：

　　<001> textured 0.675Pb(Mg1/3Nb2/3)O3-0.325PbTiO3 (PMN-32.5PT) ceramics were prepared by templated grain growth with micron scale BaTiO3 platelet templates.0%~7% excess PbO was added to form liquid phase.The influence of liquid phase concentration on the growth of matrix and templated grains was investigated.The growth process was controlled by a dissolution-precipitation mechanism.The templated grain growth was accelerated by the formed liquid phase and resulted in highly textured PMN-32.5PT ceramics.
