Influence of Sintering Temperature and Sintering Aid on Electrical Properties of (K, Na)NbO3-LT Ceramics
In this paper, 0.95K0.5Na0.5NbO3-0.05LiTaO3 ceramics were synthesized by conventional mixed-oxide technique. To clarify the optimal sintering condition, three kinds of different temperature conditions were used. It was found that the samples sintered near 1130 °C had the best piezoelectric properties (d33~155 pC/N). In addition, sintering aid such as K5.4C1.3Ta10O29 was investigated to confirm whether it really benefited to the sintering process and increased the piezoelectric property of ceramics.
