High and Frequency-Insensitive Converse Piezoelectric Coefficient Obtained in AgSbO3-Modified (Li, K, Na)(Nb,Ta)O3 Lead-Free Piezoceramics

AgSbO3 was doped into KNN‐based lead‐free piezoceramics with an optimized composition of Li0.02(Na0.53K0.48)0.98Nb0.8Ta0.2O3 (abbreviated as LKNNT) to further enhance its piezoelectric property. The doping of AgSbO3 was found to be effective in reducing the grain sizes, resulting in more uniform mic...
