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

IEEE Trans Ultrason Ferroelectr Freq Control. 2013 Oct;60(10):2044-52. doi: 10.1109/TUFFC.2013.2795.

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 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/cm(2) and 75 pC/N, respectively.
