Abstract

A comparative study has been attempted for microwave and conventional sintering of lead-free <TEX>$Bi_{0.5}Na_{0.5}TiO_3(BNT)$</TEX>-based multilayer ceramic actuators(MLAs). It was found that microwave sintering (MWS) could be successfully applied to the co-firing of piezoceramic/AgPd MLAs with a 10 times shorter firing cycle as well as <TEX>$100^{\circ}C$</TEX> lower firing temperature (<TEX>$850^{\circ}C$</TEX>) for sufficient densification than conventional furnace sintering (<TEX>$950^{\circ}C$</TEX>). Furthermore, MWS-derived specimens showed better electric field-induced strain than that of CFS-derived specimens by effectively suppressing interdiffusions between ceramic and electrode layers.
