CuO가 (Pb)(La,Nd)$TiO_3$ 세라믹스에 첨가시 미세구조와 전기적 특성에 미치는 영향

Effect of CuO on the Microstructural and Electrical Properties of (Pb)(La,Nd)$TiO_3$ Ceramics

In this study, microstructural and electrical properties of (Pb)(La,Nd)TiO$_3$ ceramics were investigated as a function of CuO addition. Taking into consideration Tc of 3$25^{\circ}C$, dynamic range of 49dB( at the wafer form) and density of 7.71g/㎤, it can be concluded that the specimen S2 sintered at 120$0^{\circ}C$ is the best for the resonator application. Dynamic characteristics of energy-trapped 20MHz SMD type resonator as a function of internal dot size variation were also investigated. Dynamic range characteristics showed the highest value of 60.72dB at S2-4(dot size 1.13mm).
