▼ [20a-P6-3] Post-annealing and quenching effect on electrical property in BaTiO3-Bi(Mg1/2Ti1/2)O3- BiFeO3 piezoelectric ceramic
キーワード：Piezoelectric materials, Bi-based ceramics
Lead-based piezoelectric materials have been widely used in various applications for their excellent
properties. However, the worldwide environmental regulations have restricted lead-based materials. Therefore, it is important to find lead-free piezoelectric ceramics. Recently, the BiFeO3 (BF)-based ceramics is being considered as replacements for lead-based piezoelectric materials. In this work, the effect of A site / B site molar ratio, post-annealing temperature and holding time, and quenching on the ferroelectric and piezoelectric properties was investigated for Mn-added 0.3BaTiO3-0.1Bix(Mg1/2Ti1/2)O3-0.6BiFeO3(BT-BxMT-BF, x=0.95, 1.00, 1.03, 1.05, 1.08) piezoelectric ceramics.
