Dielectric Properties of La, Sm Ion-Doped BST-Based Ceramics
It is important to develop a new special material to meet the requirement of advanced industry. The BST (Ba0.8Sr0.2TiO3) 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 Tc of matrix material to a low temperature and making peak wider. The calcining temperature of samples was 1280 °C.
