A facile route to prepare lithium niobate (LiNbO 3 ) powders was proposed by an alternative solid-state method. Stoichiometric Li 2 C 2 O 4 and ammonium niobium oxalate were mixed with small amounts of water and then dried at room temperature. It was demonstrated that Li[NbO(C 2 O 4 ) 2 ]โขnH 2 O int

Potassium sodium niobate (KNN) piezoelectric ceramics and KNN substituted with lithium (Li + ) and antimony (Sb 5+ ) have been synthesized by the conventional solid state sintering method. This work focuses on the phase transition in the KNN system at potassium (K + ) content of approximately 0.35.
The generalized Gruneisen parameters of elastic waves propagating in different directions in lithium niobate are calculated from the measured second-and third-order elastic constants. There are a large number of longitudinal acoustic gammas that are negative. Some of the transverse elastic gammas ar
