Dielectric Properties of La, Sm Ion-Doped BZT-Based Ceramics
It is important to develop a new special material to satisfy the requirement of producing capacitor with higher property. BZT(Ba(ZrxTi1-x)O3) ceramics of La2O3 and Sm2O3 doped was fabricated by the conventional method of solid reaction. These ceramics were tested by X-ray diffraction (XRD), Impedance Tester, and LCR Tester with temperature controlling systems. The results indicate that dielectric property of BZT ceramics doped 0.05mol% La2O3, 0.2mol% Sm2O3 simultaneously and calcined in 1280°C is the best. Moreover, it was found that Sm2O3 had the functions of moving Tc of matrix material to a low temperature and making the peak wider.
