Abstract： |
A non-Pb piezoelectric bismuth sodium titanate-barium zirconate titatate ceramics, (Bi0.5Na0.5)TiO3-xBa(Ti1-yZry)O3 (BNT-BZT), is prepared by two-step sinter method. Its advantages are high density, low leakage current in polarizing procedure, and high piezoelectric and ferroelectric performance. |
