摘要: Alkaline niobate ANbO3 (A=K, Li and Na) ceramics were fabricated into the composites of K0.5Na0.5NbO3 (KNN) NaK2Li2Nb5O15 (NKLN) phases. The NKLN phase was composed completely filled tetragonal tungsten-bronze LiNbO3 structures. (1−x)KNN–(x/5)NKLN composite displayed alloy effects with changing x. expected to be solidified KNN through liquidus–solidus curve ceramics. showed ferroelectric distortions orthorhombic symmetry. We discussed dielectric properties
