摘要：

(Bi0.5Na0.5)(0.94)Ba0.06TiO3 ceramics doped with Li2CO3 and Bi2O3 as sintering aids were manufactured, and their micro structural, dielectric and piezoelectric properties were investigated. All specimens could be well sintered at a low-temperature of 1080 degrees C. The bulk density of the specimens doped with a small amount of Li2CO3 was enhanced. The dielectric and piezoelectric properties of ceramics were investigated with different amounts of Li2CO3 substitutions. High electrical properties of d(33) = 167 pC/N, k(p) = 0.34, P-r = 40 mu C/cm(2) and E-c = 38 kV/cm were obtained from the specimen containing 0.1 mol% of Li2CO3 sintered at 1080 degrees C.
