没有人做pzt陶瓷了啊？

用铌铁矿预合成法，组分合适的时候，该赝二元体系的压电性能可以达到500-600pC/N。不需要热压工艺的。

国外最好的是0.3pzn-0.7pzt，d33为690，现在重复他的，重复不出来

能达到690应该做了掺杂或这是用热压，或者是其他新工艺。

这个体系pzn多了容易产生焦虑石，

Abstract
Solid solutions of the perovskite structure, (1  x)Pb(Zr1/2Ti1/2)O3–xPb(Zn1/3Nb2/3)O3 with x = 0.1–0.5, were synthesized via the columbite–(
wolframite) precursor method. The phase development of calcined powder precursors was analyzed by X-ray diffraction. Phasepure
perovskite of PZN–PZT ceramics was obtained over a wide compositional range. The microstructure and piezoelectric properties
were characterrized by means of scanning electron microscopy (SEM), d33 measurements and impedance analysis. It has been found that
ultra-high piezoelectric properties were observed in compositions close to a morphotropic phase boundary (MPB). The maximum value
of d33 (690 pC/N) and the highest kp (0.7) were recorded for the composition x = 0.3 located at the boundary between tetragonal and
rhombohedral ferroelectric phases. Furthermore, large values of d33 (600 pC/N) and kp (0.67) were observed at a compositions of
x = 0.5, which is the boundary between two ferroelectric rhombohedral phases.

4. Conclusions
Columbite (ZnNb2O6) and wolframite (ZrTiO4) precursors
were utilized to prepare highly pure PZN–PZT solid
solutions. Superior piezoelectric properties were obtained
in the compositions located close to the two MPBs found
in this system. The maximum value of d33 (690 pC/N)
and the highest kp (0.7) were recorded for the composition
x = 0.3. Furthermore, high values of d33 (600 pC/N) and kp
(0.67) were also observed at composition of x = 0.5，

另外奇怪的是，另一位泰国学者引用他这篇文献时却提到0.3pzn-0.7pzt的d33只有400多
