Effects of CuO nanoparticles addition on properties of PMNT ceramics

This research investigates the role of CuO nanoparticles addition on properties of 0.9PMN–0.1PT (PMNT) ceramics. Phase purity, density, microstructure, dielectric and ferroelectric properties of the ceramics were investigated. The density of the ceramics reaches a maximum when 0.5 wt% of CuO is added into the ceramics while grain size of the ceramics tends to increase with the increase in CuO content. εmax of the ceramics tends to increase with increasing CuO concentration. The improvement of Pr of the ceramics is observed in the ceramic incorporated with over 0.1 wt% of CuO.
