Abstract
A coprecipitation method was used for preparation of 0.95Pb(Mg0.8Zn0.2)1/3Nb2/3O3-0.05PbTiO3(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-xZnx)1/3Nb2/3O3-0.05PbTiO3, (1-y)Pb(Mg0.7Zn0.3)1/3Nb2/3O3-yPbTiO3 was also analysed.
