Sodium niobate – NN (NaNbO 3 ) powders were synthesized by hydrothermal process to be used as template particles in the fabrication of textured lead free piezoelectric ceramics. Sodium hexaniobate–Na 8 Nb 6 O 19 ⋅13H 2 O particles with rod-like morphology were synthesized at 120°C. Particles with needle-like morphology and Na 2 (Nb 2 O 6...
In this study, random and textured potassium sodium niobate (K,Na)NbO3 ceramics were fabricated in ribbon form through a combination of alginate gelation process and template grain growth methods. Development of crystallographic texture as a result of varying sintering time and temperature was evaluated through rocking curve analysis and a texture with Lotgering factor of 0.86 was achieved. The electrical...
In this study, sodium niobate powders were prepared by hydrothermal process for further use as template particles in the texturing of piezoelectric potassium sodium niobate fibers. At the end of the study, three different structures were obtained: Sodium hexaniobate particles with rod-like morphology at 120°C, particles with partially needle- like morphology at 130°C–140°C and SOMS particles with...
