(Bi0.5Na0.5)0.94Ba0.06TiO3 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 °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 d33 = 167 pC/N, kp = 0.34, Pr = 40 μC/cm2 and Ec = 38 kV/cm were obtained from the specimen containing 0.1 mol% of Li2CO3 sintered at 1080 °C.
► Li2CO3 doped 0.94(Bi, Na)0.5TiO3-0.06BaTiO3 ceramics were synthesized. ► The proper amount of Li2CO3 was effectively decreased the sintering temperature from 1200 °C to 1080 °C. ► The bulk density of the ceramics was enhanced by doping a small amount of Li2CO3. ► High electrical properties of d33 = 167 pC/N, kp = 0.34 and Pr = 40 mC/cm2 were obtained for the ceramics sintered at 1080 °C.
