Symp on Piezoresponse Force Microscopy and Nanoscale Phenomena in Polar Materials, ISAF/ECAPD/PFM -- 9 July 2012 through 13 July 2012 -- Aveiro -- 93333Lead-free potassium sodium niobate (KNN) ceramics were prepared with lithium modification. Copper oxide was also added as sintering aid. Impedance spectroscopy was used as a tool to analyze electrical behavior of ceramics as a function of frequency from 100 Hz to 10 MHz at various temperatures. © 2012 IEEE.eninfo:eu-repo/semantics/closedAccessCurie temperaturedielectric propertiesimpedance spectroscopylead-freeLi-modified KNNConference Object
