Effect of ZnO nano-particulates on structure and properties of PZT/ZnO ceramics

In this research, effect of ZnO nano-particles on structure, mechanical and electrical properties of PZT ceramics was investigated. X-ray diffraction result suggested that tetragonality of PZT decreased with increasing ZnO content. Density tended to increase with an addition of ZnO while grain size...
