Abstract

Lead free piezoelectric ceramics (BaTi1-xHfx)O3 with x=0.00, 0.04, 0.08 (abbreviated as BT, BHT-1 and BHT-2) were prepared by ceramic method. The structural phase formation has been investigated by using X-ray diffraction. The polarization (P) versus electric field (E) i.e. P-E hysteresis measurements confirm the ferroelectric nature with sufficiently high remanent polarization, Pr &
