摘      要：Barium titanate(BaTiO) is historically the first ceramic piezoelectric material and shows the high possibility to be revitalized as a popular lead-free piezoelectric *** decades,BaTiO ceramics had been known to exhibit the low piezoelectric activity with the d value only at a level of 191 pC/N or lower,being much inferior to the
