Development, 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 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...
متن کاملLEAD-FREE BNKT PIEZOELECTRIC ACTUATOR
An actuator is a device that converts input energy into mechanical energy. According to various types of input energy, various actuators have been advanced. Displacement in the electromagnetic, hydraulic and pneumatic actuators achieve by moving a piston via electromagnetic force or pressure, however the piezoelectric actuator (piezoceramic plates) displace directly. Therefore, accuracy and spe...
متن کاملGrowth and Characterization of Lead-free Piezoelectric Single Crystals
Lead-free piezoelectric materials attract more and more attention owing to the environmental toxicity of lead-containing materials. In this work, we review our first attempts of single crystal grown by the top-seeded solution growth method of BaTiO₃ substituted with zirconium and calcium (BCTZ) and (K0.5Na0.5)NbO₃ substituted with lithium, tantalum, and antimony (KNLSTN). The growth methodology...
