Fabrication of [001] Textured KSr2Nb5O15 (KSN) Piezoelectric Ceramics in Fiber Form by a Combination of Novel Alginate Gelation Method and Templated Grain Growth and their Electrical Characterization
Abstract :
[001]-oriented textured KSr2Nb5O15 ceramic fibers were fabricated by a combination of novel alginate gelation method and templated grain growth. Needle like KSr2Nb5O15 template particles were used for this process. Fibers were drawn from alginate based slurries without or with 10 wt% KSN template particles. A texture fraction up to 0.95 was obtained in the case of 10 wt%. Piezocomposites with 1-3 connectivity were prepared from the KSN fibers and their electrical and electromechanical properties were investigated. Highly enhanced properties were observed with increasing texture fraction such as, piezoelectric charge coefficient of up to 75 pC/N and remnant polarization of ~20 μC/cm^2.
