Nb-based systems have been considered to be the most attractive ceramic system in the research field of lead-free piezoceramics, since excellent piezoelectric properties were reported in (Li,Na,K)NbO3-based solid solution (LNKN) systems. This article reviews the characteristic and recent research activity for several kinds of the niobate systems including LiNbO3, NaNbO3, KNbO3, tungsten-bronze niobate. The importance of material design for enhancement of piezoelectric properties and their stability in the wide temperature range is also described for LNKN system.
