Dielectric Properties of BCZT-KNN Lead-free Ceramics
Abstract：Lead-free （Bao. 9z Ca0.0s ） （Tio. 95 Zr0.0s ） O3-x （Nao. 5 K0. s ） NbO3 （BCZT-xKNN） ceramics were prepared successfully using a solid-state reaction technique. The effect of KNN content on structure, grain growth and dielectric properties were studied. XRD results show that BCZT-xKNN ceramics are pure perovskite structure and no second phase are detected. The KNN content causes inhibition of grain growth and downward shift of Curie temperature （To）. The highest dielectric constant （t＇----6 330） are obtained for the samples at x----0.04.
