چکیده
Comparative studies of the pyroelectric properties and structural features sodium niobate sodium-potassium ceramics obtained under different technological conditions for synthesis have been carried out. X-ray phase analysis revealed existence an additional with chemical formula NaNb 10 O 18 in ceramic samples that do not exhibit ferroelectric properties. It is shown temperature material determine nature macroscopic polarization both pure niobate. Keywords: piezoelectric ceramics, lead-free materials, polarization, effect.

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 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 کاملDielectric 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...
