Heat Capacity and Dielectric Properties of the PNN-PT Ferroelectric Ceramics

A synergistic approach to attain high piezoelectricity in a Pb(Ni, Nb)O3–Pb(Lu, Nb)O3–PbTiO3 system

“…4,5 Recently, there has been a strong appetite in exploiting superior performance perovskite systems on the basis of the Pb(Ni, Nb)O 3 -PbTiO 3 (PNN-PT) and Pb(Mg, Nb) O 3 -PbTiO 3 (PMN-PT) piezoelectrics. [6][7][8][9][10][11][12][13][14][15][16] For instance, ultrahigh However, most binary or multiple systems still exhibit mediocre piezoelectricity and also do not exhibit significant advantage in the application of precision and sensitivity of piezoelectric devices. Therefore, the development of excellent piezoelectric ceramics is bound to better meet the increasing demand for modern electronic equipment for high-performance piezoelectrics.…”

Dielectric, Ferroelectric and Piezoelectric Properties of Pb(In1/2Nb1/2)O3-Pb(Ni1/3Nb2/3)O3-PbTiO3 Ternary Ceramics Near Morphotropic Phase Boundary

“…These systems near the morphotropic phase boundary (MPB) display outstanding piezoelectric and dielectric properties [3][4] . As a typical relaxor ferroelectrics, Pb(Ni 1/3 Nb 2/3 )O 3 -PbTiO 3 (PNN-PT) have attracted great attention due to its excellent dielectric constant (ε' > 4000) and piezoelectric coeffiecient (d 33 =450 pC/N) near MPB region [5][6] . On this basis, PNN-based binary and ternary systems, such as Pb(Ni 1/3 Nb 2/3 )O 3 -PbTiO 3 (PNN-PT) [7] ,…”

“…Fistly, the relatively low electric polarization intensity and high leakage current induced by the variable valence of Ni ions, following inferior piezoelectric coefficients [10] . Secondly, PNN-PT binary system exhibit relatively low Curie temperature near MPB region (120 ℃), which limit its application in high temperature [7][8]11] . Therefore, the addition of other compo- These ternary systems have been confirmed to have high Curie temperature and excellent piezoelectric properties [12][13][14] .…”
