摘要: Recently, it was reported that the alkaline niobate-based (K,Na,Li)(Nb,Ta,Sb)O3 (LF4) perovskite ceramics showed excellent piezoelectric properties and have been regarded as a new candidate of lead-free materials. However, effects additives on property LF4 not studied intensively so far. In this study, effect CuO addition to investigated. The sample tetragonal phase at room temperature also second with low melt point. With 0.05 wt% added, Cu2+ firstly incorporated into A site, while higher amounts substituted B-site ions. CuO-doping changed “hard” improvement mechanical quality factor from 26 137 but d31 constant electromechanical coupling reduced drastically same time.
