摘要
(1-x)(Bi1/2Na1/2)TiO3-xBiAlO(3) [BNTA100x (0 <= x <= 0.014)] ceramics were prepared by a conventional ceramic fabrication process. Single-phase perovskite structures were formed when x <= 0.08 for BNTA100x. The depolatization temperature, T-d, at which piezoelectricity disappears, decreased with increasing x. The piezoelectric constant, d(33), increased with increasing x because of the increase in free permittivity accompanied with decreasing Td. d(33) and the electromechanical coupling factor, k(33), of BNTA6 were 93 pC/N and 0.41, respectively. Normalized strain d(33)* (= S-max/E-max) at 60 kV/cm at the maximum field-induced strain was 122.2 pm/V for BNTA8. The value of d(33)* was higher than the calculated value of d(33).
