Microstructural and piezoelectric properties of PZN substituted PMN-PZT ceramics for multilayer piezoelectric transformer

Abstract

In this paper, in order to develop the low temperature sintering ceramics for multilayer piezoelectric transformers, Pb[(Mn 1/3 ,Nb 2/3 ) 0.07 (Zn 1/3 Nb 2/3 ) a (Zr 0.48 Ti 0.52 ) 1-0.07-a O 3 ] ceramics were prepared with the variations of PZN from 2 to 14 mol% and their dielectric and piezoelectric properties were investigated. Sintering temperature was varied from 940 to 1000 • C. At 8 mol% PZN substituted specimen sintered at 970 • C, electromechanical coupling factor(kp), mechanical quality factor(Qm), dielectric constant and peizoelectric constant(d 33 ) showed the optimal values of 0.536, 1803, 1551 and 328[pC/N], respectively, for multilayer piezoelectric transformer application.
