Lead-Free Piezoceramics. —
<001> textured (K0.44Na0.52Li0.04)(Nb0.84Ta0.10Sb0.06)O3 polycrystals exhibit
03- 016 Highly
piezoelectric properties comparable to those of lead zirconium titanate ceramics which
are high-performance piezoelectric materials. The properties of the Pb-free piezoelectric ceramic are due to the existence of a morphotropic phase boundary in the alkaline
niobate-based perovskite solid solution. It is expected that the new material is a leading
candidate for environmentally friendly piezoelectric devices. — (SAITO, Y.; TAKAO,
