Abstract

In this paper, We have studied about the microstructure of the piezoceramics PZT that were added with some kinds of additives, such as Niobium(Nb), Iron(Fe) or Manganese(Mn). The grain size of PZT ceramics was decreased with increasing the amounts of additive of Nb or Fe, while increased with increasing Mn. The curie temperature was changed slightly for the PZT ceramics containing $Fe^{3+}$, which is not dependent on the amounts, but $Nb^{5+}$ or $Mn^{2+}$ ion added PZT was lowered. The resistivity was increased with increasing the amounts of $Nb^{5+}$ additive, while decreased for $Mn^{2+}$ additive.
