The results indicate that the sintering temperature obviously influences the structural and electrical properties of the sample. For the 0.98NKN-0.02BZT ceramics sintered at 1,080A degrees C to 1,120A degrees C, the bulk density increased with increasing sintering temperature and showed a maximum value at a sintering temperature of 1,090A degrees C. The dielectric constant, piezoelectric constant [d (33)], electromechanical coupling coefficient [k (p)], and remnant polarization [P (r)] increased with increasing sintering temperature, which might be related to the increase in the relative density. However, the samples would be deteriorated when they are sintered above the optimum temperature. High piezoelectric properties of d (33) = 217 pC/N, k (p) = 41%, dielectric constant = 1,951, and ferroelectric properties of P (r) = 10.3 mu C/cm(2) were obtained for the 0.98NKN-0.02BZT ceramics sintered at 1,090A degrees C for 4 h.
