In this research, lead-free piezoelectric Sodium potassium niobate nanopowders (K0.5Na0.5)NbO3 were synthesized using a modified sol–gel method. Nitrate sodium, nitrate potassium, and ammonium niobate oxalate were used as starting materials. Gelatin which is natural polymer was used as polymerization agent and distilled water was used as solvent. The crystal structure of the prepared powders is...
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 determi...

Sodium potassium niobate piezoceramics are considered as lead-free piezoelectric due to their good properties. In this study, the effect of titanium dioxide and molybdenum oxide as dopant on the densification behavior, piezoelectric and dielectric properties of lithium doped sodium potassium niobate ((K0.5Na0.5)0.94Li0.06NbO3, KNNL) was investigated. For this purpose, (K0.5Na0.5)0.94Li0.06Nb0.9...
One-dimensional (1D) nanostructures of ternary complex oxides have drawn intensive interest because of their novel size-dependent properties, such as ferroelectric,1a multiferroic,1b and superconductivity.1c Various synthetic approaches, such as aqueous route by employing hydrothermal reaction2 or templates,3 molten-salt synthesis,4 and composite-hydroxide-mediated synthesis5 have been develope...
In this paper, we present a new approach to the fabrication of integrated silicon-based piezoelectric diaphragm-type biosensors by using sodium potassium niobate-silver niobate (0.82KNN-0.18AN) composite lead-free thin film as the piezoelectric layer. The piezoelectric diaphragms were designed and fabricated by micro-machining technology and chemical solution deposition. The fabricated device w...
