Abstract
The texture control of polycrystalline ceramics is an important and effective way to improve the piezoelectric properties of lead-free ceramics without drastically changing the composition of the ceramics. The screen-printing multilayer grain growth (MLGG) technique is now successfully applied to perovskite-structured lead-free piezoelectric ceramics. Grain oriented (Na0.5Bi0.5)0.94Ba0.06TiO3 (NBBT) ceramics with (100) orientation were fabricated. The influences of sintering time, heating rate, and pre-reaction at low temperature on grain orientation were studied. Highly textured NBBT ceramics (f ~ 92%) were obtained with a high heating rate. The interface between adjacent layers, which was formed by screen-printing, was the main mechanism for the texture development in MLGG technique. Compared with other grain orientation techniques, screen-printing is a simple and effective method to fabricate grain oriented lead-free piezoelectric ceramics.
