Textured lead-free KSr2Nb5O15 piezoelectric ceramics, fibers and piezocomposites — Processing and properties

Abstract

Textured ceramic fibers were fabricated from the tungsten-bronze type piezoelectric KSr2Nb5O15. Development of crystallographic texture was evaluated through rocking curve analysis and a texture with Lotgering factor of 0.97 was achieved. 1-3 piezocomposites were prepared from the textured fibers and their electrical properties were evaluated. Highly enhanced properties were observed with increasing texture fraction.
