    Electrical properties and impedance spectroscopy of modified potassium sodium niobate ceramics
    (2012) Alkoy E.M.; Yavuz A.B.; Avdan D.; Alkoy S.
    Lead-free potassium sodium niobate (KNN) ceramics were prepared with lithium modification. Copper oxide was also added as sintering aid. Impedance spectroscopy was used as a tool to analyze electrical behavior of ceramics as a function of frequency from 100 Hz to 10 MHz at various temperatures. © 2012 IEEE.

    Fabrication of piezoelectric ceramic hollow fibers with low sintering temperature and their characterization
    (Institute of Electrical and Electronics Engineers Inc., 2014) Mensur-Alkoy E.; Kaya M.Y.; Avdan D.; Unver M.U.; Alkoy S.
    The main aim of this study is to fabricate hollow fibers using alginate gelation method and to characterize the electromechanical performance of these fibers with microtubular structure for the device applications that are based on hollow piezoceramic fibers working in d31 mode. However, fabrication of hollow fibers is difficult and problematic. This study originally presents a holistic solution to these problems and it is different from the currently used or investigated methods in terms of method, design, composition and application. The novel points of the study are: fabrication of the hollow fibers by alginate gelation methods, investigation and use of solid solutions of lead zirconate titanate (PZT) with lead zinc niobate (PZN) with low sintering temperatures, preparation of Ag based electrodes during the processing of piezoceramic fibers and using the co-firing process due to the difficulty of obtaining the inner electrode layer. © 2014 IEEE.
