Resum
Dense lead-free (K0.44Na0.52Li0.04)(Nb0.86Ta0.10Sb0.04)O3 piezoelectric ceramics are prepared by the conventional mixed oxide method. The effect of different sintering conditions (synthetic air, O2 and Ar) on some structural, dielectric and piezoelectric properties is studied. A long sintering time (16 h) promotes the formation of a secondary phase, which is assigned to K3LiNb6O17, tetragonal tungsten-bronze. High values of longitudinal piezoelectric constant are obtained when ceramics are sinte...
