A coprecipitation method was used for preparation of 0.95Pb[(Mg0.8,Zn0.2) 1/ 3 Nb2 /3]O3-0.05PbTiO3(PMZN-PT),dielectric ceramic powder. X-ray powder diffraction and electron probe energy dispersive, X-ray analyzer revealed that the powder calcinated at 800℃ for 2 h is the PMZN-PT with 100% single perovskite phase, and the order of magnitude of atomic proportion of Mg to Zn reaches approximately 10: 1. In addition, the influence of Zn and Ti content on the perovskite phase and pyrochlore phase formation namely : 0.95Pb[(Mg1-x Znx) 1 /3Nb,2/3]O3 -0.05PbTiO3, (1-y)Pb[(Mg0.7Zn0.3) 1 /3Nb2 /3] O3-yPbTiO3 was also analysed.
