Structure and Dielectric Tunability of Ba (Ti_1-yZr_y)O₃ Ferroelectric Ceramics

Abstract:

Barium zirconate titanate Ba(Ti1-yZry)O3 (BZT, y = 0.02, 0.07, 0.09, 0.12, 0.15) ceramics have been prepared by sol–gel process. All the BZTx ceramics exhibited perovskite phase detected by X-ray diffraction, and the diffraction peaks shift to lower angle with increasing the content of Zr. Dielectric susceptibilities are up to 15500, and tunability up to 74.9% under electric field 6.8 kV/cm at 100 Hz.
