Abstract
The screen-printing multilayer grain growth (MLGG) technique is successfully applied to alkaline niobate lead-free piezoelectric ceramics. Highly textured (K 0.5Na 0.5)NbO 3 (KNN) ceramics with 〈0 0 1〉 orientation ( f = 93%) were fabricated by MLGG technique with plate-like NaNbO 3 templates. The influence of sintering temperature on grain orientation and microstructure was studied. The textured KNN ceramics showed very high piezoelectric constant d 33 = 133 pC/N, and high electromechanical coupling factor k p = 0.54. These properties were superior to those of conventional randomly oriented ceramics, and reach the level of those of textured KNN ceramic prepared by tape-casting technique. Compared with other grain orientation techniques, screen-printing is a simple, inexpensive and effective method to fabricate grain oriented lead-free piezoelectric ceramics.
