Abstract: The additive is classified by electrovalency, the effect on capability of PZT dual- system piezoelectric ceramic of each sort of additives is dis cuss ed and the reason why each sort of additives can change the capability of PZT dual- system piezo- electric ceramic is analyzed. The res earch indicates that the adding quantity of each additive has a fitting range.
Keywords: piezoelectric ceramics, PZT dual—system, additive
