Effect of la 2O3 addition on electrical properties of PZN-PZT based ceramics

In this study, compositions in the 0.2Pb(Zn1/3Nb2/ 3)O3-0.8Pb(Zr1/2Ti1/2)O3 based systems will be developed based on the material engineering approach (processing vs. electrical properties). This work involves the fabrication of high purity PZN-PZT based in ceramic forms, and a study of La2O 3 addit...
