Abstract

The effect of lithium salts (Li₂CO₃, LiNO ₃, LiF) addition on sintering temperature and electrical properties of 0.68Pb(Mg_1/3Nb_2/3)O₃-0.32PbTiO₃ ceramics were investigated. All the samples with lithium salt additions show a typical liquid phase sintering character. The samples with LiNO₃ and LiF addition sintered at 1100°C have dense structure. The dielectric loss decreases for the samples with the Li₂CO₃ and LiNO ₃ addition, but increases for the samples with LiF addition. The sample with LiF addition sintered at 1150°C has good piezoelectric properties, which d₃₃ is 620pC/N and K_p is 64%. All these may be attributed to the anionic (F^--O^2-) substitution.
