摘要：

PMN-PT ceramics were prepared using eutectic composition NaCl-KCL. The effect of PbO or MgO on phase structure and dielectric properties of PMN-PT ceramics was investigated. The phase structure in powders and ceramics was identified by means of X-ray diffraction. It was found that the dielectric loss decreased remarkably with addition of excess MgO, but increased slightly with addition of excess PbO ceramics.
