Electronic Properties of Lead-Free (Ba0.95Ca0.05)(Ti0.92Sn0.08)O3 Piezoceramic Nanofibers by Electrospinning

Lead-free (Ba 0.95 Ca 0.05 )(Ti 0.92 Sn 0.08 )O 3 , (BCTS) piezoceramic nanofibers were prepared by electrospinning acetate precursor solutions in polyvinyl pyrrolidone, followed by calcining at 1150ºC for 2 h. X-ray diffraction of calcined nanofibers confirmed the formation of the BCTS phase and en...

Beschreibung
Zusammenfassung:	Lead-free (Ba 0.95 Ca 0.05 )(Ti 0.92 Sn 0.08 )O 3 , (BCTS) piezoceramic nanofibers were prepared by electrospinning acetate precursor solutions in polyvinyl pyrrolidone, followed by calcining at 1150ºC for 2 h. X-ray diffraction of calcined nanofibers confirmed the formation of the BCTS phase and energy dispersive x-ray analysis confirmed the presence of Ca and Sn ions. The scanning electron microscope studies showed cylindrical fibers with a diameter in the range 80–275 nm. The dielectric constant and piezoelectric charge constant ( d 33 ) were 3485 at 100 Hz, RT and 398 pC/N, respectively.
