Processing and properties of textured potassium strontium niobate (KSr2Nb5O15) ceramic fibers-effect of texture on the electrical properties

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 that are 2 to 3 times higher than the random case were observed with increasing texture fraction with P_r and d₃₃ reaching 20 μC/cm² and 75 pC/N, respectively.
