Sintering 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 کاملGrowth and Characterization of Single Crystals of Potassium Sodium Niobate by Solid State Crystal Growth
Due to the toxic nature of PbO in Pb(Zr,Ti)O3 (PZT), the most common type of piezoceramic, many studies on lead-free materials are being conducted worldwide (Röedel et al., 2009). One of the most studied groups of lead-free ferroelectric materials is based on a solid solution of potassium sodium niobate, K0.5Na0.5NbO3 (KNN) (Jaffe et al., 1971; Kosec et al., 2008). However, activity in attempts...
متن کاملStudying the Effects of Nano Sintering Additives on Microstructure and Electrical Properties of Potassium-Sodium Niobate Piezoceramics
In this paper, lead free (K0.48,Na0.52)NbO3 (KNN(48-52)) piezoelectric ceramics were made by conventional solid state sintering process. Additives of nano ZnO (n-ZnO), nano CuO (n-CuO) and nano SnO2 (n-SnO2) were used in order to decrease the sintering temperature, as well as modifying the dielectric, piezoelectric and ferroelectric propert...
متن کاملPotassium Sodium Niobate-Based Lead-Free Piezoelectric Multilayer Ceramics Co-Fired with Nickel Electrodes
Although lead-free piezoelectric ceramics have been extensively studied, many problems must still be overcome before they are suitable for practical use. One of the main problems is fabricating a multilayer structure, and one solution attracting growing interest is the use of lead-free multilayer piezoelectric ceramics. The paper reviews work that has been done by the authors on lead-free alkal...
متن کاملOptimized Single-Mode Cavity for Ceramics Sintering
In this paper, we present a novel method of optimization of a single-mode cavity used for sintering ceramics. The goal of the optimization is to maximize the electric energy stored in the dielectric and minimize spatial variations of tashis field in the domain occupied by the material. Results of simulations of two configurations are discussed.
