0.9Pb(Mg1/3Nb2/3)03-0. lPbTiO3 phase with the addition of ZnO was prepared by NaCl-KCl molten salt synthesis. Sinterability and dielectric properties of the specimens were investigated as a function of amount of ZnO. For the specimens sintered at 1100°C with 2 mol% ZnO, the pyrochlore phase of 12% present disappeared completely and the relative density reached a maximum value 97%. With further additions, the density value decreased. These results were mainly related to the microstructure changes including grain size and formation of a second phase. Dielectric properties had the same trend as the variation in density. Dielectric constant of about 23,500 was obtained for specimens sintered at a low temperature of 1100°C with 2 mol% ZnO.
