Abstract: Ceramics based on (K, Na)NbO3 (KNN) are piezoelectric materials that can replace lead zirconate titanate (PZT), which is widely used in piezoelectric electronic components. Because KNN is composed of elements that are less easily reduced than PZT, it can be co-sintered with Ni inner electrodes. In a previous study, KNN with CaZrO3 and MnO was found to be stably co-sinterable with an Ni electrode in a composition where CaZrO3 and MnO were added. The effects of increasing or decreasing the amount of ZrO2 in this system on the Curie temperature, dielectric, and piezoelectric properties of the bulk and multilayer KNN are investigated in this study.
