Dielectric Properties of La, Sm Ion-Doped BST-Based Ceramics

Abstract:

It is important to develop a new special material to meet the requirement of advanced industry. The BST (Ba_0.8Sr_0.2TiO₃) ceramics doped La₂O₃ and Sm₂O₃ was fabricated by the conventional method, and was tested by X-ray diffraction (XRD), Complex Impedance Testing Instrument, LCR Tester with temperature controlling systems. The results indicate that dielectric property of BST-based ceramics doped 0.05 mol% La₂O₃ and 0.2 mol% Sm₂O₃ simultaneously is the best, and Sm₂O₃ had applications of removing T_c of matrix material to a low temperature and making peak wider. The calcining temperature of samples was 1280 °C.
