Dielectric and piezoelectric properties of sodium lithium niobate Na1−xLixNbO3 lead free ferroelectric ceramics
High density sodium lithium niobate lead free ceramics near the morphtropic phase boundary [NaxLi1−xNbO3, (LNN), x=0.12] were prepared by the solid state reaction method. XRD patterns showed that the lattice structures were changed after polarization. The temperature dependence of the dielectric constant and dielectric loss, pyroelectric coefficient and DSC curves of LNN ceramics showed that th...
متن کاملDevelopment, Characterization, and Piezoelectric Fatigue Behavior of Lead- Free Perovskite Piezoelectric Ceramics
The development of lead-free perovskite piezoelectrics as environmentally compatible alternatives to lead zirconate titanate (PZT) has received significant attention recently. Two main categories of lead free perovskite piezoelectric ceramic systems were investigated as potential replacements to lead zirconate titantate (PZT) for actuator devices. First, solid solutions based on Li, Ta, and Sb ...
متن کاملFerroelectric Domain Structure and Local Piezoelectric Properties of Lead-Free (Ka0.5Na0.5)NbO3 and BiFeO3-Based Piezoelectric Ceramics
Recent advances in the development of novel methods for the local characterization of ferroelectric domains open up new opportunities not only to image, but also to control and to create desired domain configurations (domain engineering). The morphotropic and polymorphic phase boundaries that are frequently used to increase the electromechanical and dielectric performance of ferroelectric ceram...
متن کاملSintering of Lead-Free Piezoelectric Sodium Potassium Niobate Ceramics
The potassium sodium niobate, K0.5Na0.5NbO₃, solid solution (KNN) is considered as one of the most promising, environment-friendly, lead-free candidates to replace highly efficient, lead-based piezoelectrics. Since the first reports of KNN, it has been recognized that obtaining phase-pure materials with a high density and a uniform, fine-grained microstructure is a major challenge. For this rea...
متن کاملPiezoelectric Ceramics Characterization
This review explores piezoelectric ceramics analysis and characterization. The focus is on polycrystalline ceramics; therefore, single crystals, polymeric materials and organic/inorganic composites are outside the scope of this review. To thoroughly grasp the behavior of a piezoelectric polycrystalline ceramic, a basic understanding of the ceramic itself should not be overlooked. To this end, w...
