摘要
(1-x)(Bi(0.5)Na(0.5))TiO(3)-xSrTiO(3) (abbreviated as BNST100x) was prepared by a conventional ceramic fabrication process. The depolarization temperature T(d), rhombohedral-tetragonal phase transition temperature T(R-T), and the temperature T(m) of the maximum dielectric constant were determined from the temperature dependence of the dielectric and piezoelectric properties. It is revealed that BNST100x forms a morphotropic phase boundary of rhombohedral ferroelectric and pseudocubic (tetragonal) paraelectric at x=0.26-0.28 for BNST100x, and a very large strain and normalized strain d(33)* of 0.29% and 488 pm/V, respectively, were obtained at x=0.28. In addition, it was clarified that the intermediate phase between T(R-T) (>= T(d)) and T(m) shows relaxor behavior. (c) 2008 American Institute of Physics.
