摘　　要：用二次合成法制备了 0 .2 4 Pb(Fe2 / 3W1 / 3) O3- 0 .0 6 Pb(Fe1 / 2 Nb1 / 2 ) O3- 0 .5 6 Pb(Mg1 / 3Nb2 / 3) O3- 0 .14 Pb Ti O3固溶体陶瓷 ,分别研究了预烧温度和烧结温度对其预烧粉体和陶瓷的相组成的影响 ,详细研究了烧结温度及掺锰对PMN-Pb(Fe 2/3 W 1/3 )O 3-0.06Pb(Fe 1/2 Nb 1/2 )O 3-0.56Pb(Mg 1/3 Nb 2/3 )O 3-0.14PbTiO 3 ceramics was prepared by the columbite precursor method, and the effect of calcining and sintering temperature on the phase structure of the calcined powders and sintered ceramics was investigated respectively. The effect of sintering temperature and Mn doping on the dielectric properties was also explored in detail.
