%X PZN-based composite ceramics were prepared at lower sintering temperature by using fluorides and borosilicate glass as sintering aids. The correlation between the coexistence of two phases in composite ceramics and sintering aids was studied. The results revealed that the crystal lattice defects caused by additives have detrimental effect on the coexistence of two phases in composites. Incorporation of LiF into PZN crystal lattice promotes the reaction between two phases due to oxygen vacancies, while PZN-based composite ceramics with MgF2 and borosilicate glass aids maintain diphasic microstructure. PZN-based diphasic ceramics with X7R character were obtained at lowe sintering temperature by using borosilicate glass as sintering aids.
